The KYN61-40.5 630A 35KV High Voltage Switchgear is a metal-clad, armored, withdrawable indoor switchgear designed for 35kV power systems with a rated voltage of 40.5kV and rated current of 630A. It features a vacuum circuit breaker for reliable interruption and a compact modular structure that conforms to GB3906 and IEC62271-200 standards. The switchgear incorporates mechanical interlocking to prevent operational errors, and its withdrawable design allows safe maintenance without de-energizing the busbar. Typical applications include power plants, substations, industrial facilities, and mining enterprises requiring stable and safe power distribution. The enclosure is made of high-quality steel sheet with IP4X protection, and the main busbar is copper with silver-plated contacts for low resistance and long service life.
