KYNS-40.5 indoor removable metal-clad switchgear (hereinafter referred to as switchgear) is a new type of switchgear developed by our company, which absorbs the latest technology of 35kV switchgear at home and abroad. The switchgear is suitable for indoor three-phase AC 50Hz electric power system with the rated voltage of 40.5kV. It can not only receive and distribute electric power for power plants, substations, industrial and mining enterprises, but also monitor, protect and control the circuit.
The master switch adopts the latest type of VSV-40.5 series vacuum circuit breaker characterized by long service life, high breaking capacity, high protection degree, good insulation performance, safe and reliable operation and convenient maintenance and repair. The switchgear is provided with the “five-anti” function.
The switchgear conforms to GB3906 and IEC-62271-200 standards.
