The number of insulators on this transmission line is greater than 60, and its voltage level is obviously 1000 kv.
Like this, 750 kv transmission lines have more than 35 pieces of insulator.
This is a 500 kv transmission line with nearly 30 insulator plates.
And the number of insulators for the 330 kV transmission line is about 20.
For the 220 kv transmission line, the number of insulator plates is 12-14.
For a 110 kV transmission line, the number of insulator plates is approximately 7-9.
If are at high altitude, heavily polluted areas, the number of insulators will increase.
