This switch leads the new technology, which adopt the gas of SF6 as the insulator and
extinguishing medium. The contract, operation system, current transformer are all sealed
in the stainless steel case.
Adopt the principle of compressing air for extinguishing. The contract system adopt Copper tungsten alloy. It has long life electricity.
The operation mechanism is a Spring mechanism with double cam ,simple structure, high reliability ,and lead a high speed when open or close.
Whatever between outgoing and the switch or between operating mechanism
handle and mechanism, all adopt sealant to seal it. Which produced by a special rubber
called ERP series and passed the test under the temperature of -80°C.
Using inside current and potential transformer to collect the data from the network.
The body if this load switch all manufactured by the stainless steel that the
thickness exceed3mm,Skillful welding, and by rust prevention treatment.
By the effect of the desiccant inside, it could keep the internal humidity under 300ppm.
It improved the ability of anti-leakage and condensation. Free of maintenance for 30years;
