Product Definition‌

The KYN550-12 compact metal-clad withdrawable high-voltage switchgear (hereinafter referred to as "switchgear") is a new-generation product independently designed and developed by our company, based on the absorption of advanced manufacturing technologies from both domestic and international sources. It can replace various outdated models of metal-enclosed switchgear, such as the KYN1-10, JYN2-10, GBC-10, and KYN28-12 series. Both the mid-mounted switchgear cubicle and the VR1-12 vacuum circuit breaker are manufactured in-house, enabling superior quality control.
