INSULATOR Types of insulator Electrical Engineer
There are 5 types of insulators used in transmission lines as overhead insulation:
Pin Insulator.
Suspension Insulator.
Strain Insulator.
Stay Insulator.
Shackle Insulator.
Insulator description one by one compelete explain-https://www.electrical4u.com/types-of-electrical-insulator-overhead-insulator/
Grid sub station insulator uses and  Care
11kv,33kv,66kv,132kv,220kv,420kv
Advantage-https://electricalshouters.com/types-of-insulators/
Suspension type insulator are cheaper then pin type insulator for voltage beyond 33kv.
If anyone disc is damaged, the whole string does not became useless because the damaged disc can be replaced by the sound one..
Depending upon the working voltage, the desired number of discs can be connected in series.
