12kV 24kV tủ phân phối vòng không khí cách điện (RMU)

Description ：

Pioneer in China's eco-friendly switchgear sector, we have specialized in R&D and manufacturing of SF₆-free switchgear for decades. With core technologies, we have established industry standards. Boasting a fully independent end-to-end production chain, we have built a product matrix of zero-emission and high-reliability eco-friendly switchgear, making us a trusted choice for power grid construction.

SM66-12/24 unit type SF6 RMU with SF6 load switch as main switch, for whole  cabinet is suitable for electric distribution automation and compact also expandable  metal close switchgear. It characters in its simple structure, flexible operation, reliable  interlocking and convenient installation etc., which can provide the satisfactory  technical projects both for different application occasions and users. With the  adoption of sensor technology and the protection relay up to date, plus the advanced  technology and flexible assembly project, SM66-12/24 unit type SF6 RMU can  completely meet the requirement of continuously variable market. It can take  self-produced RLS-12/24 load break switch; also according to user's demand can be  assembled with the internationally top-ranking RCB series vacuum circuit breaker  with permanent magnetic mechanism made by AREVA or HD4 type SF6 circuit  breaker made by AREVA or HD4 type SF6 circuit breaker made by ABB or with our  VSC-12/24 type vacuum circuit breaker with permanent magnetic mechanism.  Operational methods for the main switch inside ring main unit can be either manual or  electric power driven. And It can meet the requirement of "Four Controls" when  matched with FTU and RTU.

Q:What is the purpose of a ring main unit RMU?

A:A ring main unit (RMU) is used to distribute electrical power in a medium - voltage distribution network. It allows for sectionalizing the network, isolating faults, and enabling power transfer between different sections of the ring - shaped power network, ensuring reliable power supply.

Q:What does the RMU stand for?

A：RMU stands for Ring Main Unit. It is a type of electrical switchgear used in medium-voltage electrical distribution systems, typically for distributing power in a ring circuit configuration.
