SF6 Ring Main Unit 25KV Switchgear
Our inflatable SF6 metal seal full insulation series ring network switch cabinet has passed the type test of the national occlusal electrical testing center. Widely used in 10KV/6K power distribution system, it is the preferred switch product for various users in urban and rural areas. switch cabinet is modular unit mode, which can be combined according to different purposes. By the combination of fixed units and expandable units, which substation meets the need of compact switchgear flexible use.
Description
SF6 Ring Main Unit 25KV Switchgear
The SF6 insulated switchgear is suitable for middle voltage power distribution system with a rated voltage of 11kV and 40.5kV. It could be used as RMUs in a power supply network, fault isolating switches and sectionalizing switches. If equipped with distribution automation devices (FTU/DTU) and communication devices, the SF6 insulated switchgear could communicate with the control center, measure the cable voltage, current, etc, and monitor the working status of
SF6 gas insulated ring main unit(RMU/C-GIS):
Safe ring/plus RMR type SF6 gas insulated ring main unit is integrating with SF6 infill cabinet which gather with LBS, VCB, Fuse, ES, DS, etc.
By the perfect integration of stationary type and flexible expansion, RMR type SF6 gas-insulating compact close metal switchgear(Ring main unit) with the adoption of the modular design, is suitable for end-user or network node, meanwhile meets the requirement of all kinds of switching substations cabinet-type transformer substations and cable branch cabinets. It characters on its compact structure, safety and reliability, longevity and maintenance free.
