Different Types of Electrical Cables

Types of Electrical Cables:

1. VIR Cable: It stands for Vulcanised Indian Rubber. It is composed of copper or aluminium conductors inside over o layer of VIR insulation.

2. TRS Cable: It contains aluminium or tinned-copper conductors covered with tough rubber sheathed.

3. PVC Cable: It stands for Poly Vinyl Chloride. It consists of copper or aluminium conductors covered with a layer of PVC insulation.

4. MS Cable: It stands for Metal Sheathed. Vulcanised rubber insulated cable covered closely fitted sheath of lead (PB).

5. Flexible Cords: Large number of fine gauges of wires make it flexible.

6. Weather Proof Cable: It consists of 3 braids of fibrous yarn compounded with weatherproofing material.

There are five systems of internal house wiring that are generally used. These are:

i. Cleated Wiring: It is used for temporary wirings such as in a puja pandal and student’s hostel requiring electricity for a short while. It is simple, cheap and easily installed.

ii. Casing Wiring: It is sued in transport and Railway lighting for low voltage domestic installation. It may be wood casing/PVC casing/aluminium casing.

iii. Teak Wood Batten Wiring: It is widely used in residential buildings, educational institutes, and commercial and industrial lighting except in the workshop. It is moderate cost & nice to look at.

iv. Metal Sheathed Wiring: It is used in places exposed to sun rays and rain and in places of dampness.

v. Conduit Wiring: Surface conduit wiring is used in workshops for motor wiring such as Library, Auditorium, etc.

Conceal Conduit: It is used in modern residential buildings, cinema halls and auditorium halls, etc.

i. Domestic Wiring: For house wiring, I suggest teak wood batten wiring with PVC cable.

ii. Workshop Wiring: For workshop wiring surface conduit with PVC cable.
