ALPS series US3.0 gas-insulated ring network switchgear, suitable for power distribution systems below 12~24kV, provides a variety of systematic solutions for ring network power supply, double radiation power supply, cable feed network industrial and commercial areas and rural towns and other areas with large power supply load and high density in a flexible and changeable functional combination.
US3.0 indoor ring main unit adopts SF6 gas insulation, and all the high-voltage live parts of the switchgear are sealed in the SF6 gas box, which is not affected by the environment, maintenance-free, and has high safety.
Adopt compact module structure, with load switch / load switch - fuse combination electrical / isolation switch - circuit breaker and other main electrical appliances to form each sealed gas box function unit, the bus bar can be expanded in the left and right directions through the bus connector, the inlet and outlet lines adopt plug-in cables, suitable for medium voltage power distribution system, can be arranged arbitrarily according to different design schemes, to complete different power distribution tasks.
