Wires - A Guide
«
on: May 24, , 10:14:54 pm »
After searching around for guides related to types of wiring used in electronics, I've found there doesn't seem to be much. For a beginner, going over to an online retailer such as Farnell and searching for wire brings back an enormous amount of products. There is bare copper wire, tinned copper wire, pvc insulated, silicone insulated, different stranding: single strand, 19/26, 26/30, etc. etc. etc.... As a beginner it becomes a daunting task trying to figure all this out and trying to find what he or she wants/needs.
SO, I ask the question: are there any guides, or could someone give us beginners some guidance as to wiring? Different types, uses, advantages/disadvantages for each, etc.
How about it folks?

I'll try to touch on some basics, and give you an idea of what direct to at least ask smart questions about any particulars. I remember being overwhelmed myself the first time I wanted to order some hookup wire from an electronics supplier, rather than use whatever scraps I could find in my parts collection (aka "junk box").
The first basic property of cooper wire (I'm going to exclude aluminum and high resistance wires) is the diameter or gauge. The two gauge standards that I am aware of are American Wire Gauge (AWG) and (British) Standard Wire Gauge (SWG).
From this you can use reference tables to determine the length per weight/mass (i.e. ft/lbs or m/kg), the maximum current carrying capacity (continuous or intermittent duty) for a given max temperature (say 100C / 212F) and maximum ambient temperature (say 57C / 134F). This may be specified by the National Electrical Code (NEC) or other local building / electrical standards depending on application or regional requirements.
The maximum safe voltage potential if determined by the insulation type and thickness. This may 300, 600, V as common examples. Otherwise the insulation type is important for physical characteristics, such as fire/flame resistant, toxicity (directly and/or from being heated or burnt), and flexibility (tight bends).
Bare copper wire is uninsulated, and may be pre-tinned as copper easily oxidized when exposure to air and moisture. Bare wire may be used as a short jumper, where being inadvertently shorted is unlikely or impossible and not a safety hazard. The only other application I can think of bare wire is as a sensor (moisture) or electrode. Otherwise it is not worth the small cost savings of not being coated in insulation.
The pre-tinned is being coated in tin metal or alloy (e.g. tin/lead) which improves solderability and reduces oxidation when exposed to air. This oxidation acts as an thin layer of insulator or forms a very poor rectifier (diode) producing unreliable and possibly confusing results.
Cable means simply a bundle or more than a single wire.
Most wire is either a single solid strand of the specified gauge or a twisted bundle of smaller diameter wires, so as to be easier to bend, and if a couple strands break it doesn't imply the entire bundle will break creating a open in the wire.
Wires and cables can able be shielded (screened) with a outer conductive layer on top of the first layer of insulation of either fine braided mesh or foil (typically aluminum) and a second insulation layer.
For normal voltage and low to modest current and power requirements, most electronic projects use a reasonable fine gauge of insulated wire referred to as "hook-up wire" in multiple colours (red, black, green, yellow, blue, and white are probably most common due to colour coding conventions). I would first select four colours in 22 AWG of solid wire with whatever insulation. Next I would add 3 or 4 colours of stranded 24 AWG hook-up for connections that will be flexed more.
Then I would add 3 or 4 colours of solid 18 AWG hook-up wire, and possibly a red/black pair of "zip-wire" (two insulated conductors in parallel, also called lamp cord) for power hook-ups of solid or stranded 18 or 16 AWG.
Over time you will add wire & cables based on application needs, such as ribbon cable for parallel data or signal connections, coax cable for radio frequency or very high speed serial usage, and magnet wire for winding your own transformers and inductors. For high-voltage applications (e.g telsa coils) you'll likely need to purchase wire with suitable high voltage insulation, and the same for power applications like power amplifiers and power supplies.

Note:
robrenz and
ejeffrey make some very good points regarding flexibility and magnet wire
Important note about wire/cables
pricing: Since approximately [1] wire and cable prices have been quite unstable as the commodity pricing of copper (metal) was quite volatile due to (real or perceived) supply shortages. Thus pricing can appear to be nonsensical, and old catalogs are useless as a price guide.
[1] I picked this year at random, but it's based on a random possibly factual graph from Wikipedia I found on the Internet. Ref: http://en.wikipedia.org/wiki/File:Copper_Price_History_USD.png as of 30 May

As to flexibility: Solid wire is the least flexible and will break from repeated flexing very quickly. the higher the stranding for the same AWG the more flexible and longer flex life. As example 22 AWG 7/30 (7 strands of 30) is the coarsest. 19/35 is common but for high repetition flexibility 168/44 might be used. Insulation affects flexibility also with silicone or rubber being the most flexible and silicone also having a high heat tolerance. That is why quality probe leads are very high stranding silicone insulated. hookup wire does not need high strand count because it is intended for infrequent flexing (assembly/repair only).

Yeah, If ya tin the wire first then you can cut it to the correct length after it has already shrunk, then you just need to apply heat for a very short time to join it to the conductor.

One type of wire frequently mistaken for bare copper is magnet wire. This is solid copper wire with a thin transparent coating. It is primarily used for winding inductors, transformers, and motors where thicker insulation would take up too much space. Because the insulation is directly bonded to the copper you can't strip it like normal insulation, you have to scrape it, dissolve it, or burn it off. You typically only use it where it will be fixed in place and protected because repeated bending can cause the insulation to crack, and it is easily damaged by abrasion or impact.

Ok.
Now, for the purpose of learning/exemplifying:

http://pt.farnell.com/carol-cable/ca-12-03/hook-up-wire-100ft-16awg-tin-copper/dp/
The two links above show two reels of hookup wire. Both are 16awg, 300v rated, red PVC insulation, 26/30 stranding, same length reels. Pretty much both seem to be the same, except that one costs twice as much as the other. WHY?

They are both tinned.
I could not get into the data sheet at that time. I have looked it up in Newark, and strangely enough, the Alpha is $69.10usd and the Carol is $38.90usd, just the opposite. I also lookd at the data sheets and I cant find any dfferece either. So, I would suggest to the OP if he needs wire, buy one of each color of the Alpha wire at Eur17 a spool and be happy to get it so cheap. I think someone at Newark/Farnell/Element14 set the price incorrectly, take advantage at that price.

From glance I do not believe it was covered. People getting started in electronics often do not know which wire guage to get for breadboard use. Some books or tutorials may cover it, many not. 22 guage seems to be the appropriate size for general use. Jumper cables that are braided for flexibility and also having a solid male headers on each end is something to go for.

Great info for youngsters! ^^^
Another tip for breadboard wire which I have used since grade school is 25 pair wire, its cheap, easy to find and it works well. I find most of it in the junk bin, still with the 50 cond centronics connectors on it, for free. It is usually 24 awg, the same size as 1/4w resistor leads, and doesn't stretch out the breadboard connections. I will say that its a bit weak strength wise for inserting into the breadboard sometimes, but nothing a pair of small needle-nose pliers cant handle. I prefer the white w/tracers as opposed to the rainbow colored stuff, but that is just personal pref. Buy a ten pack of Sharpie markers and stripe them to your needs.
I also use that for chassis wiring, say I need forteen conductors and have only ten wire colors, just use the same colors and put a black tracer on it, simple. I buy twice as much white wire than red and black because its just so handy.
For example, I have three power sources, +-5vdc,+-15vdc, and +-48vdc. I will use red (+5) and white\red stripe (-5) with black ground for +-5vdc, orange and white\orange stripe for +-15vcd with black ground, and yellow and white\yellow stripe with black ground for +-48vdc. The possibilities are limitless!
Use white w/black and orange or yellow for high voltages, white w/green and yellow for chassis\earth ground, or say, for a buss, blue -- white\blue -- blue\black -- green -- white\green -- green\black......etc, or all white wires with tracers that follow the resistor color code blk, brn, red, orn, yel.....etc.
Hope someone finds this as useful as I have...

One can gather by everyone selling jumper wires boasting "No more stripping lines apart!"
This reminds me, I am very tempted to buy a good length (actually I've got some near my desk) and make some wires. I've a spool of white tinned solid wire that serves me well, but would rather make my own than buy many $20 spools just for different colours.

Yup, some of us dont/didnt have any money growing up and had to use what we could find.
Those pre-cut/stripped wire kits were not that cheap until recently, and still cost money.
You cant beat free.
The Sharpie marker idea works great, it takes half a second to stripe a short wire. I use that alot at work building and repairing wiring harnesses. Later on it takes the guess work out of servicing it.

Here's a tip if yqou want lots of colors wires for cabling you electronics projects: go to the local junkshop and buy old printercables with db25 and centronix connectors. Theres a whole bunch of individual multistrand wires in there, each with its own color or color cobination. Printer cables are three to 4 feet long and you easily get 20 colors of wire out of it ... And most junkshops sell these for 0.5$ to 1$.. Cant beat that !

Electrical power cables are a crucial component in various projects across different industries.
From powering heavy machinery to lighting up buildings and homes, electrical cables play a vital role in enabling a wide range of applications.
With their various types, from low to high voltage cables, armored and unarmored, sheathed and unsheathed, understanding the different types of cables and their uses is essential in selecting the suitable cable for a specific project.
Electrical power cables offer a range of benefits, including efficient distribution of electrical power, minimal power loss, and extended service life.
Properly selected power cables can provide uninterrupted power supply to critical applications and reduce downtime, boosting productivity and profitability.
Additionally, using high-quality cables can reduce the risk of electrical hazards and improve overall safety in the workplace.
Knowing the suitable types of electrical power cables for a project is crucial for efficient power distribution and avoiding costly errors.
This blog post will explore the various types of electrical power cables and their applications.
Introduction to electrical power cables in projects
Welcome to the comprehensive guide on electrical power cables in projects.
As power distribution and management in any project are paramount, it is crucial to understand the different types of electrical power cables available in the market.
In this guide, we will cover the various types of electrical power cables that are commonly used, the differences between single-core and multicore cables, the importance of insulation in power cables, choosing the right cable for your project requirements, as well as the proper installation and maintenance of power cables.
By the end of this guide, readers will know the necessary to select and maintain power cables tailored to their project-specific requirements.
Types of electrical power cables
Understanding the different types of electrical power cables is crucial for any project involving installing or maintaining electrical equipment.
Ultimately, choosing the suitable cable, proper installation, and maintenance are critical for ensuring a project’s safe and effective operation of electrical equipment.
The following factors affect your decision in ordering the cables for your project:
- Voltage designation.
- Load factor.
- Required load (ampere or MVA).
- Level of short circuit current (KA) and duration (Sec).
- Environmental conditions.
- Laying conditions.
Also, You need to specify the following information to properly order the cable/wires in your project.:
- The Operating Voltage of the cable/wire.
- The material of the conductor.
- The construction of the cable.
- The insulation of the conductor.
- Conductor construction type.
- Armouring Type.
- The sheathing.
The Operating voltage
The electrical cables can be used in low-voltage, medium-voltage, high-voltage, and extra-high-voltage applications. But in this blog post, we will consider low-voltage applications.
The operating voltage in low-voltage cables can be (up to 1.8/3 KV), as the voltage of a cable will be written in the following formula U0/U (Um).
Where:
U0: The rated r.m.s. Power frequency voltage between each conductor and screen or sheath for which cables and accessories are designed.
U: The rated r.m.s. Power frequency voltage between any two conductors for which cables and accessories are designed.
Um: The maximm r.m.s. Power frequency voltage between any two conductors for which cables and accessories are designed. The highest voltage can be sustained under normal operating conditions at any time and at any point in a system.
The material of the conductor
The material of the conductor in electrical cables will affect its electrical properties like relative conductivity and electrical resistivity.
Commonly, we use one of these two types of conductors in low-voltage applications, either copper or aluminum.
Each has its advantages and disadvantages, as shown in the table below.
So, based on the above table, you will decide the type of conductor for your cables in the project.
The construction of a cable as per no. of conductors
A cable can be a single-core or multi-core.
Single-core cable, from its name, includes one core, while multi-core cable can contain more than one core, like 2, 3, 4, 5, or more, per the customer’s application and requirement.
The insulation of the conductor
The conductors of the cables shall be insulated, whether this cable is a single-core or multi-core.
If it’s a single wire only, it can be a bare copper conductor like the one used in the earthing & lightning protection systems or will be insulated.
If it’s insulated, so we will have outer insulation on the wire, but also, in some special cases, we can also have an outer jacket like Nylon, or it can have a sheath above the conductor’s insulation.
Common types of insulation to the single wires:
- PVC: Poly Vinyl Chloride.
- XLPE: cross-linked polyethylene.
- THHN: Thermoplastic High Heat resistant Nylon coated.
- THWN: Thermoplastic High Water-resistant Nylon coated.
- TFFN: Thermoplastic Flexible Fixture wire Nylon coated.
- LSF: Low Smoke & Fume.
- LSHF: Low Smoke Halogen Free.
- LS0H: Low Smoke Zero (0) Halogen.
Plus, we need to mention in our purchase order the color of the insulation of each conductor.
For example, if we purchase a four-core cable, we need to write the color of each conductor on this cable.
Usually, the color of the conductors will be one of these colors:
A- Red, Yellow, blue, black, where Black is the color of the neutral conductor.
B- Brown, Black, Grey, Blue, where Blue is the color of the neutral.
In both cases, if we use an earthing conductor, so its color will be yellow-green.
Examples:
- 1x4mm2 Cu/PVC, it’s a single-core cable with single insulation, and its type is PVC.
- 1x4mm2 Cu/PVC/Nylon, it’s a single-core cable with single insulation (PVC), and above this insulation, there’s a nylon protection layer.
- 1x4mm2 Cu/PVC/PVC, it’s a single-core cable with double insulation, one on the conductor and one as the outer sheath of the cable. The insulation type of both conductor and sheath is PVC.
But if the cable is a multi-core cable, so we must have outer insulation for each conductor, plus we will have outer sheath insulation.
The common types of low-voltage conductor insulation can be summarized as follows:
- PVC: Poly Vinyl Chloride.
- XLPE: cross-linked polyethylene.
Conductor Construction Type
Regarding the construction of the conductor itself, there are three types of low-voltage conductors, stranded, flexible, and solid.
For more PVC Insulated Cablesinformation, please contact us. We will provide professional answers.
You can learn the difference between these types as seen in the photo below.
Armouring Type
Cables can be armoured or not. It depends on whether the cable will be under mechanical forces or not.
So, if there is a chance the cable will be under mechanical forces or stress, so the cable will be an armoured cable.
There are different types of armouring, as follows:
STA: Steel Tape Armouring
SWA: Steel Wire Armouring
ATA: Aluminum Tape Armouring
AWA: Aluminum Wire Armouring
The sheathing
The sheathing is the final outer layer of the cable. Usually, its material is made from PVC.
We will use it to protect the cable’s conductors plus to form a homogeneous circular shape for the cable to be easily rolled over cable drums and easily pulled in its ducts, trays…etc.
Last but not least, in some cables, you can find a bedding layer between the conductors and the sheath or between the
How to read the cables in Electrical Drawings?
This is the most important section of this article.
Generally, the cable description will be written from the inner side to the outer side.
This means the description will start with the number of conductors in the cable, the type of conductor’s material, and so on until you reach the cable’s outer sheath.
And if we have multiple cables installed between two locations, and they are parallel of the same cross-section area, we will add the number of parallel routes before the description of the cable.
For a better understanding, please check the following examples.
Examples of different types of cables:
Example 1:
1x70mm2 Bare Copper Conductor.
