MV Distribution Air insulated pole mounted load break switches LBS11-15KV

Short Description:

The (H)GW series outdoor Air/Load breaker switch is a three-phase AC 50Hz /60Hz outdoor medium-voltage switchgear, which can open and close the power line and can see the obvious disconnect distance.

Application voltage levels include 12kV, 24kV and 36kV.

Application standard: IEC62271-102

General

All overhead power transmission lines require an Air Break Switch, which is primarily used to connect or disconnect (on/off switching) the power system of a specific section of overhead line and transformer from the main distribution line. This enables the user to isolate a section of the overhead wire without disrupting the remaining power transmission system.
