Chennuo Electric's handcart vacuum contactor successfully passed the type test of the Soviet Academy of Sciences

VCNR handcart type vacuum contactor-fuse combination electrical appliance is an intelligent energy-saving switchgear independently developed by our company by introducing European technology and combining it with the current development of the power industry. This product utilizes a high-voltage fuse capable of interrupting a wide range of short-circuit fault currents, a vacuum contactor capable of frequent operation, and a comprehensive relay protection device. 

It can be used for frequent starting of motors or frequent switching of transformers and capacitors. VCNR products can be assembled in 650mm or 800mm wide center-mounted switch cabinets.

VCNR handcart type vacuum contactor-fuse combination electrical appliance is a new type of indoor switchgear with epoxy resin insulation (or solid sealing insulation). It is suitable for three-phase AC power systems with rated voltage 7.2KV~12KV and rated frequency 50Hz. It has the advantages of long life, frequent operation, stable operation, reasonable functions, low cost, low noise, and small floor space. The products are used in thermal power plants, metallurgy, petrochemical and other industrial and mining enterprises as switching equipment to control and protect high-voltage motors, transformers, induction furnaces and other loads.

This time, Chennuo Electric's handcart-type vacuum contactor successfully passed the type test of all projects of the National Electrical Products Supervision and Inspection Center (Suzhou Electric Power Research Institute), which marks that the quality and performance of our company's products can withstand verification, and will open up new opportunities for our company in the future. The market has laid a solid foundation.
