In the world of insulation material types for wire and cable, there are always fresh improvements and different sorts of alternatives, each of which allows different wiring products fulfill certain tasks.
as One of the most significant components of electrical product today, the type of insulation, also known as an electrical insulator will be described.
Before digging into the wide range of the numerous chemically formed insulations, let’s first go over the objective of electrical insulation.
As the name says it’s an insulator meaning it keeps things (electrical) within.
Wikipedia defines it as "a substance whose internal electric charges do not flow freely or have very little electric current flow through it under the action of an electric field (Wikipedia)."
There's a great number of wiring insulations, which range from practically identical chemical components to being completely distinct.
electrical cable insulation types pdf
Searching through pdf files titled electrical insulation types usually used to coat copper wire (and other) electrical conductors, we often face two classifications: first, Thermoplastic and second, Thermoset.
What’s the difference? If we have a look at our Fundamentals of Rome Wire and Cable Manual (yeah, it’s from a long time ago but yes, it’s still totally valid), we have the following descriptions: Thermoplastic: This substance is one that will soften and even melt when subjected to a sufficiently high temperature.
In other words, when the material is originally created, it becomes somewhat rigid yet malleable, much like most plastics we encounter in our daily lives.
However, if it is exposed to high temperature at some future period, it softens and melts.
The key rationale for adopting a thermoplastic material is that it is the most affordable type of insulation.
cable insulation types chart
There are numerous types of wire and cable insulation material showcased in chart type information, this typification is based on application.
Plastic, Rubber, and Fluoropolymer are the three main insulating materials.
Following is a list of wire and cable insulation materials with descriptions of their common applications, benefits, and drawbacks.
Insulation for wires and insulation for cables are essentially same.
Wire insulation is the process of isolating a single conductor, which is the definition of a wire.
When discussing cable insulation, we typically refer to a cable composed of many (wire) conductors.
Insulation of a cable can refer to the type of insulation surrounding each wire or to the insulation of the cable as a whole; the type of insulation and level of insulation for your cable will rely on the use case of your application.
copper wire insulation material
In addition to pvc which is the most prevalent insulation material.
various forms of insulation material include; polyethylene (pe) ,Polypropylene (PP) Polyurethane (PUR), Chlorinated Polyethylene (CPE), Nylon Polyethylene (PE) (PE) PE is widely utilized in coaxial and low-capacitance cables because of its exceptional electric properties.
It is widely used in these applications since it is inexpensive and may be foamed to reduce the dielectric constant to 1.50.
This makes PE a common alternative for cables requiring high-speed transmission.
Polyproylene insulation (PP) is quite similar to PE but has a larger temperature range of -30° Celsius to +105° Celsius.
It is used mostly for thin-wall primary insulations and can be foamed to increase its electrical characteristics.
wire insulation types and uses
Insulation is a crucial component of every electrical wire and cable.
Each type of insulation has unique applications; it is constructed of nonconductive material and covers the wire.
Also known as an electrical insulator.
PLASTIC INSULATION Polyvinyl chloride (PVC): PVC is resistant to moisture, fire, and abrasion and can be utilized in a variety of conditions, including those containing acids, solvents, and ozone.
In addition to lacking taste and odor, PVC-insulated wires are non-toxic.
This material can withstand temperatures ranging from -55°C to 105°C.
Semi-rigid (SR) PVC: SR-PVC has similar resistance qualities to PVC insulation, but this material is superior when high abrasion resistance is essential.
