FKN12-12D series air-blast Ioad break switch and FKRN12-12D series air-blast load break switch-fuse combination apparatus are new series switchgear applies to three-phase electric distribution system of rated 12kV, acting as protecting and control apparatus for transformers, cable and overhead wiring. These series are especially applicable in rural, urban terminal substation and prefabricated substations, as well as ring network power supply. FKN12-12D can break and make Ioad current and over-current. FKRN12-12D can break and make over-current load current and short-circuit current(Iimited current fuse). This product is featured with impact structure aesthetic appearance. reliable interlock and high insulating level. In the spring storage operation mechanism, ON/OFF speed is free from the influence of the manpower. For the arc-extinguish, electric arc-extinguish inside the insulating cover, the free gas occurs at sparking do not cause descend of insulating level between phases and phase to earth. The insulation cover clapboard separates electrified part thus boost protection grade of ring main unit. The copper-tungsten contact and main contact brings along reliable conductivity and long life. This product achieves sound fame due to easy maintenance and operation as well as reliable performance. It is in compliance with IEC62271-105.

The High-Voltage AC Switch for Grounding is a vital safety device in high-voltage power systems, designed to facilitate the grounding and isolation of electrical equipment during maintenance operations. It operates effectively at voltage levels between 12kV and 40.5kV, showcasing robust short-circuit withstand capabilities and reliable mechanical functionality. With its compact design, it ensures straightforward installation and user-friendly operation, making it suitable for high-voltage switchgear and substations. Compliant with rigorous international standards, this grounding switch provides consistent safety and performance in demanding electrical conditions.

FZRN21 series Ac and HV indoor vacuum load break switch, this product has a breaking capacity, safety and reliability, long life, can operate freguent, compact structure, small size, light weight, the basic no need to maintain. FZN21-12 series high-voltage vacuum load switch is mainly composed of framer, disconnecting switch (current-limiting fuse of the combiner is in the disconnecting switch), vacuum switching tube, grounding switch, spring operating mechanism and so on. This product has compact structure, small volume, long life, strong closing and breaking capacity, and easy operation and maintenance. The vacuum switch is equipped with a spring-operated mechanism, which adopts an electric motor (another manual) spring energy storage, and there are two types of closing methods: electromagnet closing and manual splitting and closing. The disconnecting switch, vacuum switch and earthing switch are interlocked with each other (mechanical interlocking) to prevent misoperation. FZN21-12D/T630-20, FZN21-12DR/T125-31.5 type high-voltage vacuum load break switch and fuse switch are operating in three-phase AC electrical 12kV, 50Hz power distribution system, with a compact, small size, light weight, long service life, high making and breaking ability, safe and reliable, and if load switch cooperated with fuse namely fuse switch can replace those fuses with higher cost, easy and convenient operation and maintenance
