Introduction:
HXGT6-12 SF6 Ring Main Unit Switchgear (following abbreviation RMU) is my corporation designs and
developed by self according to our country power supply requirement. Being suitable in our country city power
network need of transformation and construction, it is a new generation indoor 10kV piezoelectricity ware
product, this product is through type test and the operating examination, and the performance index achieves
IEC298 of AC metal closed switch standard and others of country standard. It possesses the merits of small
volume, gently quality, simple operates, use safety, high reliability, not influent by environment and climate and
exempts maintenance, etc.
The RMU is a combined electrical equipment with all the main return circuit switch seals up in a metal envelope
aspect and SF6 gas regard to extinguish arc and insulation dielectric, it is suitable not only in ring power supply
and the double radiation power supply of 10kV medium pressure power supply network, but also can be used
by terminal power supply. Owing to use ring net power supply, the reliability of power supply is greatly raised, so
the product is especially suitable in factories and mines, residence area, school and park, etc. As distribution
and control of electric energy. Moreover, owing to the fact that its convenient wiring and small volume and
convenient installation, it can also be fit for combined power station as side HV equipment of the station.
General
The GIS is suitable for power plant, substation, combined substation and electric power system, which is three
phase indoor AC single busbar and sectioning single busbar with 50Hz, 35kV rated voltage, used to control,
accept and distribute electric power.

Functional design
1. Reliable: Each compartment is monitored individually & has its own pressure relief device.
2. Safety: The primary side components are hermetically enclosed, gas filled compartment and thus insensitive
to atmosphere, dirt &dust.
3. Space saving: Smaller foot prints All operations on the switchgear front.
4. Economically efficient:Reduced space & surface area requirement. Long service life Maintenance free Gas
compartment.
