Product Description

Product introduction
XGT2(XGN)-12 Box Type Fix Type AC RMU Switchgear (side install type) (following abbreviation switch ) is used
in 10kV three-phase AC 50Hz indoor system as accepting and distributing electric energy, especially suitable in
the occasion of frequently operates. The bus system is one bus. This switch fits the requirement of national
standard GB39063~35kV's AC metal closed switch and IEC298, and possesses tightly the shutting meritability
of "five guards "This switch apparatus has been surmounted old type fixed switchgear's defects such as the
switch volume is huge and the maintenance is not convenience, etc. And has surmounted moving out type
switchgear's defects of complicated handcart organization, once connection the protection operation
organization is unreliable, etc. It is a new small model fix type seitchgearof researching and developing by self.
The main switch that this switchgear adopting is VT2A-12's mould side loading type vacuum circuit breaker
developed and designed by self.
GT7(GN)-12 series designed by self is selected as upper and down disconnecting switch.

The switch process list:
Reliable electrically connection.
Convenient examined and repaired.
Installation of once cable can be accomplished before the cupboard.
Product can be installed by the wall.
Use the isolation switch and ground connection switch operation organization and interlock device of
integrationization design, the operates and interlock is convenient and reliable.
Once component is vertial range.
The breaker room, bus room and cable room have leak pressure channel.
The frame is combined by applying aluminium zinc board,
It is the smallest volume in the fixed switch of double disconnection switch in the internal: Wide X deep X height
= 750 X1100 X2100mm.Box Type Fix AC Ring Main Unit Switchgear;
