HEC400 series of products for intelligent Schneider RM6 SF6 insulated medium voltage ring main unit, the electric energy storage mechanism for electric energy storage in order to achieve open and close. The design concept has advanced techniques, processing and accurate installation without adjustment. Motor independent design, torque, long life; gear mainly imported engineering plastics and aluminum alloy, durable; controlling part adopts integrated circuit boards, wiring with plug wiring, a substantial increase in production efficiency. Product configuration of the motor unit, drives, control unit, plug wiring unit. Can be achieved:? Remote / local switching and place points, closing operation. ? Load switching, grounding switch status, fuse status indication and remote signaling in situ. ? Users simply plug connection according to Figure logo, a few minutes to complete the tedious work of secondary lines.
