Product Overview
Our company can produce products with voltage classes ranging from 1kV to 40.5kV and below. The product is a complete set of power distribution devices composed of a high-voltage circuit breaker, load switch, contactor, high-voltage fuse, isolation switch, ground switch, transformer and station transformer, as well as control, measurement, protection, regulation devices, internal connectors, auxiliary shell and support parts.
The cabinet structure is assembled by bending and welding steel plates, and the protection level is IP2X. The upper part of the cabinet is the busbar room, and the instrument room is located in front of the busbar room and is separated by steel plates. The middle part of the cabinet is a switch room, and an insulating partition is arranged between the switch and other components.
