Product Code : KYN28-12(Z)
Brand Name : BIG PAWER ELECTRCIAL TECHNOLOGY
Product Description
High Voltage Metal Enclosed Switchgear is utilized for ensuring uninterrupted flow of power in power plants. In power substation, it is used for smooth receiving and transmitting electricity to various electrical systems that include motor under high voltage level.

It consumes 3.6~12KV voltage and its standard voltage frequency is 5oHz. This system is meant for indoor utilization purpose. The manufacturing standard of this switchgear conforms to IEC-298, DL404 and GB3906 specifications. It possesses five different safety features that include power application during earth position of earthing switch, pushing and pulling load via cart, circuit breaker malfunction detection arrangement, electrical mis-entering of compartment and closing as well as opening function of earthing switch.
