The
conductors of the overhead lines are
stranded
solid
both (a) and (b)
none of the
above
both (a) and (b)
An electrical
conductor may be either a solid or a stranded type. The solid type conductor
has only one solid core or wire, the stranded are made by twisting a number of
wires together.
The most common conductor in use for transmission today is aluminium conductor in use for transmission. Also seeing much used is all-aluminium alloy conductor (AAAC).
Aluminum is
used because it has about half the weight and lower cost of a comparable
resistance copper cable.
Hence, the
correct option is (C).
