In electrical engineering, a disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. They are only used for breaking the circuit and are often found in electrical distribution and substation, where machinery must have its source of driving power removed for adjustment or repair. Disconnectors can be manual or motor operated and may be paired with an earthing switch to ground the portion that has been isolated from the sys......
Summary
Outdoor disconnector? switch?used in 15kV,27kV and 38 KV power distribution systems, with current from 200 to 630A. And it used as switching on and switching off at the voltage with no load.
