Category Ring Main Unit

Description

HXGN-12 type fixed metal-enclosed switchgear (hereinafter referred to as ring main unit) is a 12kV rated voltage, 50Hz rated frequency AC high-voltage complete electrical equipment, mainly used for three-phase AC ring network, terminal distribution network and industrial power equipment, for receiving and distributing electric energy, etc. It is also suitable for high-voltage installation.

Overview
　　The HXGN-12 box-type fixed metal-enclosed switchgear (hereinafter referred to as ring network cabinet) is a 12kV rated voltage, 50Hz rated frequency AC high-voltage complete electrical equipment, mainly used for three-phase AC ring networks, terminal distribution networks and industrial power equipment, for receiving and distributing power. It is also suitable for high-voltage installation.
Usage Environment Conditions
　　•Uses a full-set device structure, lightweight and beautiful, can be arbitrarily combined and installed, easy to infinitely expand and extend.

　　•Can be equipped with FKN12-12 type pneumatic indicating load switch, combination electrical appliance, or FZN25-12 type vacuum load switch, combination electrical appliance, and the installation dimensions are completely consistent. Small size, maintenance-free, three-phase linkage structure, and remote control function.

　　Manual and electric operation are available, and it has a remote control function.

　　It has a complete and reliable mechanical linkage and interlocking device, fully achieving the “five-prevention” function.

　　The load switch uses a linkage protective insulating valve to shield the energized handle, ensuring personal safety.

　　The front door is equipped with an observation window, which can clearly observe the working status of the components inside the cabinet.

　　Complies with GB3906, GB11022 and other standards.
