Product overview
The KYN61-40.5 armored removable AC metal enclosed switchgear is mainly characterized in that the cabinet is equipped with a ZN85-40.5 fully insulated vacuum circuit breaker and a spring operating mechanism. It can also be equipped with ABB's VD4-40.5 and HD4-40.5 cabinet body, which is assembled by spraying aluminum-zinc plate and cold-rolled steel plate, thus increasing the matching accuracy between the handcart and the cabinet body. The handcart is very easy to push and pull out and has strong interchangeability. Beautiful appearance, complete scheme, safe and reliable use.
This product is used in 35kV three-phase AC 50Hz power system, as a power plant, substation and industrial and mining enterprises in the distribution room to receive and distribute electric energy, with control, protection and monitoring functions.
This product complies with GB3906(3 ~ 35kV AC Metal-enclosed Switchgear ", GB/T | 022" Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards ", DL/T404" Technical Conditions for Ordering AC High Voltage Switchgear ", IEC60298" Rated Voltage 1kV Above 52kV and Below AC Metal-enclosed Switchgear and Control Equipment "standards.
