Question

Describe the material used as conductors in cable.

Conductor As the name suggests should be able to conduct electricity with negligible resistance

The properties of such conductor should be

Very low specific resistance

Very high conductivity

Ductile – drawn into wires

Malleable .

Various metals are used for usage as conductors e.g. copper, aluminium, platinum in some case. All these have good conducting properties. Usually conductor are made of quenched standard

Copper which may be circular or shaped.

The normal usual voltage on ship is 440V and cables for use at this voltage are designated 600/1000V – 600V to earth or 1000V between conductors. Higher voltage need cables rated at 1900/3000V for earthed neutral system and 3300/3300V for insulated neutral system.
