Medium Voltage RMU SF6 Load Break Switch 10kV 630A For Incoming Line

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, the conductive 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 the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.
4. 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.
5. Small size, light weight, maintenance-free, easy and safe to operate.

Normal working Environment

1. Altitude: ≤1000m
2. Ambient temperature at -30ºC to +40ºC, the daily average temperature should not more than 30ºC.
3. The daily average of relative humidity is less than 95%, the average monthly is less than 90%.
4. Working environment should be without steam, gas, chemical corrosive deposition, salt fog, dust, dirt and other dangerous explosive media, which will severely impact on insulation and conductivity of products.
5. Working environment should not be regular vibration or serious bumps.

PS: Products with special requirements, specifications and dimensions that need to be improved can be designed and manufactured according to user requirements.
