Description

We make continuous efforts to really improve the quality of Metal Armored Removable Switchgear, Cast Resin Dry Type Transformer, compact switchgear and effectively drive the improvement of the quality of domestic related products. With the development and enlargement of mass clients abroad, now we have set up cooperative relationships with many major brands. We know that if we want to achieve rapid development, we must actively implement the strategy of quality, brand and standardization, we rely on independent research and development and innovation, so as to achieve product diversification, superior quality, comprehensive customers and service integration. Our company has its own spot warehouse and has a large number of inventory all year round in order to meet the needs of customers. With the integration of the global economy and the rapid development of industry, competition between companies has increased.

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;


Widely used in power plants, substations, and other electrical equipment,as the protection and control of electrical facilities,especially for the place where the goods are frequently operated under rated current and the multiple breaking current.
