●GB3804-2004 High-voltage Alternating-current Switches for Rated Voltage above 3.6kV and less than 40.5kV

● GB/T 11022-1999 Common Specifications for High-voltage Switchgear and Controlgear Standards

● DLT593-2006 Common Specifications for High-voltage Switchgear and Controlgear Standards

●GB16926-2009 High-voltage Alternating Current Switch-Fuse Combinations

● GB/T 1985-2004 High-voltage Alternating-current Disconnectors and Earthing Switches

● GB/T 15166-94 High-voltage Alternating-current Fuses

◆Operating conditions

● Ambient air temperature Limit +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:II.

Basic Functions And Features

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

opening,earthing.

2.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.

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

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

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