Answer / shan

one disc can withstand 11kv so that in 11kv we are using one insulator the same if 22 kv we use 2 disc and in 33 we use 3 disc if 132 kv we use 12 disc i.e(11kv * 12 = 132kv)

Answer / kinslevel

The Disc is made in
such a way that each
Disc can withold 11kv.
So, you can only use 2
of the Disc if perhaps
you want to increase
the transmitting
voltage to about 22kv
or more.

Answer / chrisanand00

The above said all answers are correct. And the Disc designed to withstand 8KV and Impulse withstand voltage is 15KV. It is designed for phase to ground not for phase to phase.

Answer / mishra

the Disc designed to withstand 18KV so it can work without get puncher at 11Kv
the number of discs snnected by the formula
18*(KV * fluctuating voltage)
where fluctuating voltage is plus minus 6% according to IER in OH lines
