Introduction
The KYN550-12 is a compact and highly insulated switchgear among the current switchgears with removable centers. It is designed for use at altitudes up to 3000 meters and features APG solid insulation and silicone rubber sealing technology. The KYN550-12 modular, fully-sealed, solid-insulated, metal-armored removable switchgear (hereinafter referred to as the switchgear) is suitable for complete devices with single buses and bus sections in three-phase AC systems with a frequency of 50Hz and rated voltages ranging from 3 to 10kV. It is primarily used for power transmission from small and medium-sized generators in power plants, power distribution in industrial and mining enterprises, power transformation and transmission in secondary substations of power systems, and starting of large high-voltage motors. It serves the functions of control, protection, and monitoring.
