BQRM16-12 is a metal enclosed switchgear insulated with SF6 gas, which can be composed of modules such as load switch unit, load switch fuse combination electrical unit, vacuum circuit breaker unit, and busbar incoming unit. Adopting a series of advanced technologies and materials, it has excellent electrical and mechanical properties.
◆Product Summary
SRM□-12 Full Gas Insulated RMU is indoor cabinet type AC metal sealed switching device,with AC 10kV and 50/60Hz.It issuitable for distribution systems,ring power supply and biradial power supply system in factories,workplaces,residential high-risebuildings,it possesses functions of receiving,distribution and protection.It can also used in the prefabricated substation.
◆Environmental Conditions
1.Ambient Temperature:No more than+40℃,No less than -40℃.Average temperature no more than +35℃ within 24 hours.
2.Altitude:No more than 2000m.
3.Relative Humidity:the average daily value is no more than 95%,the average monthly value is no more than 90%.
4.Earthquake Intensity:No more than 8 degrees.
5.Vapor Pressure:the average daily value is no more than 2.2kPa,and the average monthly value is no more than 1.8kPa.
6.Installation locations without fire,explosion danger,serious pollution,chemical corrosion and violent vibration.
◆Product Features
1.Fully sealed design,all 10kV switches and busbar electrified bodies are sealed in the gas box welded by 3mm stainless steel plate,and the silicon rubber cable plug is applied to achieve the full insulation seal of the cable head,so that it is not affected by externalenvironment such as dust,humidity and small animals.
2.The switching device has a perfect five-preventions,with simple and clear operation procedures.
3.Modular design.Each unit module can be combined and extended arbitrarily,which is easy to schemes combination,with a wideapplicable range.
4.Big capacity for feeder line,small occupation,suitable for a variety of needs,wide range of applications.
5.Equipment maintenance-free,highly reliable performance.
