Which material is most preferred for wiring continuous bus bar?
Right Answer is:
A wide range of busbar systems is available and can be used for single or three-phase distribution to many types of applications ranging from lighting to heavy-duty machines in factories. This consists of copper or aluminum busbars mounted on insulators and enclosed in standard lengths of steel trunking, which are arranged to be fitted together thus forming a continuous busbar along the entire length of the distribution route. It is sometimes more economical to use busbars in place of long runs of sub-main cables.
In the case of an isolated phase bus system of continuous type, the enclosures are electrically continuous throughout the length. Aluminum is used for wiring continuous bus bars because its cost is lesser than copper.
