International new technology HV AC Load Breaker Switch

General:

 The load breaker switch is a collection multifunctional medium voltage switchgear of gates, sub-gate, earthing. In a fully sealed with strengthen the structure of the epoxy resin housing to filled with SF6 gas,0.05MPa, with the minimum parts to achieve the above three functions, to ensure product quality, improve reliability, maintenance-free. It can be safely run for more than 20 years in normal conditions.

Service Environment

• Ambient air temperatureLimit+40℃; Lower-25℃;

• Above sea level1000m;

• Relative humidity: daily average is less than 95%, on average less than 90%;

• Seismic intensity of not more than 8 degrees;

• No fire, explosion, chemical corrosion and severe vibration in the workplace;

• Contamination level: IL.

• Key Feature

• Load breaker switch adapts double fracture, rotary movable contact structure, with the following three kinds of operating states:Closing,opening, earthing.

• Using SF6 gas as an arc extinguishing and insulating medium, the main circuit seals by the upper and lower housing pouring epoxy resin, theconductive function is unaffected by external influences.

• Good safety performance. If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.

• Load breaker switch sets gates, opening, earthing switch three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock, compact structure, high security and reliability.

• Small size, light weight, maintenance-free, easy and safe to operate.
