If the number
of poles in an 11 kV transmission line is 80, then how many disc insulators are
required?
80
240
160
6
6
Disc
insulator will be installed at the first and
last end of the transmission line and 78 pole will be fitted with pin insulator
The number of
disc insulator each pole is 3
Hence the number of disc insulator for 2 pole = 3x2 = 6
The number of
pin insulator for 78 pole = 78x3 = 234
Hence, the
correct option is (D).
