Description

'Focus on future development, and constantly innovate services' is our company's unremitting corporate spirit, and we have gradually developed into one of the major SF6 RMU Switchgear, Pole Mounted distribution transformer, switching station suppliers. We take 'excellent quality, accurate delivery, and considerate service' as our promise, and look forward to sincere cooperation with you! We uphold the concept of customer first and serve customers attentively, and customize personalized services for customers.

The side mounted indoor vacuum circuit breaker is suitable for 12kV voltage, as a protection and control unit of power equipment, industrial and mining enterprises, it can be used for switching loads of various kinds and frequent operation, repeatedly breaking short-circuit current situation. The product adopts new type of circuit breaker, a VSG part can adopt the international brand of embedded pole, the vacuum interrupter and the main circuit part is fixedly sealed into a whole, protect the interrupter from collision, dust and gel image, strong ability to adapt to the environment, greatly reduces the cost of operation and maintenance. The real implementation of the product part of a maintenance free, low maintenance operation mechanism;
