Pin insulators can be divided into porcelain pin insulators and composite pin insulators in accordance with insulator materials. Pin insulator shall be manufactured, tested and designed in accordance with IS: 731/1971 and IEC: 61109 / 92-93.
porcelain Pin insulators
The porcelain pin insulators shall generally conform to IS: 731/ 1971 and any amendments up to the same.
Pin insulators main technical parameters:
Nominal system voltage | kV | 11 | 22 | 33 |
Corresponding highest system voltage | kV | |||
Frequency | 50Hz with 3% tolerance | |||
Neutral earthing | Effectively ground | |||
Min. impulse withstand voltage | kV | 75 | 125 | 170 |
We also produced ANSI and IEC pin insulators or manufactured by clients’ requirements.
