Single-phase switch disconnector is a single-phase hookstick operated switch, used for isolating from *2kV overhead transmission line. It is widely used to combine with circuit breaker or load switch to provide safe visible isolating distance for circuit. The switch can realize switch on-off operation in the state of non-load.
The product conforms with the standard as follows:
|
IEC ********2 |
3.6KV**0.5KV high voltage alternating isolated switch and earthing switch |
|
GB/T ****2 |
