Product Description:

HXGN-12 AC Metal Enclosed Switchgear (referred to as Ring Main Unit) is a new type of high-voltage switchgear produced for the renovation and construction of urban power grids. In the power supply system Used for breaking load current and short-circuit circuit, as well as making short-circuit current.This ring network cabinet is equipped with a vacuum load switch,and the operating mechanism is a spring operated mechanism.

This mechanism can be operated manually or electrically. Manual combination of grounding switchand isolating switch The operating mechanism of this ring network cabinet is strong in completeness, small in size, without combustion and explosion hazards,and has reliable "five prevention" functions.


Structure features:

◆ Adopting a fully assembled structure, it is lightweight and beautiful and can be installed in any combination,making it easy for unlimited expansion and extension.

◆ It can be equipped with FN12-10 type compressed air load switch and combination appliance,as well as FZN25-12 type vacuum load switch and combination appliance, and the installation dimensions are completely consistent. Volume Small, maintenance free,three-phase linkage structure, with obvious isolation fractures.Equipped with FN12-10 type compressed air load switch and combination electrical appliance, the installation method is flexible and can be installed on both sides,front or back.

◆ It can be operated manually and electrically, and has remote control function.Equipped with complete and reliable mechanical linkage and interlocking devices, it fully achieves the "five prevention" function.

◆Adopting a linked protective insulated valve to block live contacts and ensure personal safety.

◆ Adopting positive operation and maintenance, reliable wall installation.The front door is equipped with an observation window,which can clearly observe the working condition of the components inside the cabinet.

◆ Complies with GB3906 standard.


Ordering instruction:
