Load break switch(LBS) is broadly utilized in the medium voltage and high voltage industry for switching and security purposes. They are well known in the market for isolating electric current vision in a compact structure that makes contributions to area saving installation and operational convenience.
Vacuum circuit breakers are also used with switching on and off the electric supply. The selection between the two relies on the client, but commonly, a load break switch partnered with a vacuum circuit breaker is a more reliable selection.
In general, load break switch has two types, the SF6 load break switch and air load break switch. In the air blast type, the interrupter heads, the same as those used for isolation purposes in air-blast circuit breakers, are employed for making and breaking currents. In SF6 type LBS, the gas serves as an insulating and arc quenching medium.
