Non-Metallic Sheathed Cable- These are also known as non-metallic building wire or NM cables. The main feature of these type of cables is- they have a plastic jacket that covers two or more wires. These are commonly used for the underground or outdoor usage.

Underground Feeder Cable- These cables are quite similar to Non-Metallic sheathed cable, but in underground feeder cables, all the wires are grouped and wrapped in a flexible material. These are available in different varieties. They are often used for outdoor lighting and in-ground applications. They have high water-resistance that makes them ideal for moist areas like gardens as well as open-to-air lamps, pumps, etc.

Metallic Sheathed Cable- These types of wires are often used to supply electricity from the main manufacturing unit to the industries. Basically, they are required to run large appliances. This type of wire consist of three wires. One is for current, one is for the grounding wire and third one os a neutral wire. They are covered with the PVC sheathing and also known as PVC wires. They are used for outdoor applications and high-stress installations.


Coaxial wires- A coaxial cable has a tubular insulating layer which protects an inner conductor. In this the two inner shields share the same geometric axis, these cables are normally used for carrying television signals and connecting video equipment.

Ribbon Cable- They are often used in computers and peripherals, with various conducting wires that run parallel to each other on a flat plane, leading to a visual resemblance to flat ribbons. Ribbon Cables are quite flexible and can control applications that require low voltage.

No material can stand strong the in the wiring industry without a good thermal coefficient in terms of expansion, in this case being 80 x 10-6

Apart from the above mentioned physical attribute PVC has a high max cont use temp of 60 degrees with  an impressive density of 1.38 g/cm3. However, the positive qualities do not end here. On a scale of 1-4 where 1 being poor and 4 being very good PVC has the following implications in chemical resistance.

Dilute Acids– Score of 4- Verdict: Very Good
Dilute Alkalis– Score of 4- Verdict: Very Good
Greases and Oils– Score of 3- Verdict: Good
Alcohols– Score of 3- Verdict: Good

When talking about hydrocarbons PVC has very resistance to aliphatic hydrocarbons while it works fairly for aromatic and halogenated hydrocarbons. Hence, due to its unmatched physical and chemical attributes PVC is considered as one of the best materials to be used in the wiring industry and it is advisable to use it in any new projects or while replacement in the old ones.

What Are The Advantages Of Using PVC Wires?

After polyethylene and polypropylene, polyvinyl chloride (PVC) is the third mass produced synthetic plastic polymer.  There are two basic forms of PVC, rigid and flexible. While rigid form is prominently used in the production of pipes, bottles, packaging and cards, insulated electrical cables, signage, imitation leather and inflatable products are produced from PVC mixed with plasticizers.
PVC WirePVC cables are versatile, high in tensile strength, flexible, good conductors and easy to joint. Due its dynamic properties these wires are commonly used for home appliances, wiring of circuits, house wiring, power supply solutions, instruments, submarines, mining operations, ship wiring etc.
