KYN61-40.5 Indoor Metal-Clad Removable Type Switchgear

Product Description:
The KYN61-40.5 indoor metal-clad removable type switchgear is independently developed by our company, incorporating advanced 35kV switchgear technologies from both domestic and international sources. It is suitable for indoor three-phase AC 50Hz power systems with a rated voltage of 40.5kV. It is used in power distribution rooms of power plants, substations, and industrial enterprises for receiving and distributing electrical energy, while providing monitoring, protection, and control of circuits.

The main switch uses the ZN85-40.5 series vacuum circuit breaker, which features long service life, high breaking capacity, high enclosure protection, excellent insulation, safe and reliable operation, and convenient maintenance. The switchgear also incorporates a “five-proof” design.

The product complies with GB 3906 and IEC 62271-200 standards.
