Air break switch are three-phase disconnector with air break, for pole top horizontal and vertical installation, usually also called load break switch,it used as switching on and switching off in 11kV-33kV Distribution line.and it with capability for breaking small magnetizing transformer currents and small currents on overhead lines.It suitable for all types of networks, especially those requiring frequent maneuvering under severe climatic conditions,likes saline humidity, sand, snow, high altitude, industrial pol......
We have two types air break switch:
– RH-B-F1 Air break switch equipped with an air cutoff device consisting of high-speed stainless steel whips for a breaking capacity of 50A.
– RH-B-F2 Air break switch with arc quenching chambers that can provide breaking capacity up to 100A.
They are equipped with a manual operator for closing and opening.
