Box Type Fixed Metal Clad AC Medium Voltage Cabinet Ring Main Unit Switchgear
Products Overview
HXGT8 series RMU are new product in order to upgrade the projects of for the urban and rural power grids by virtue of benefiting from the advantages of other RMU and overcome its disadvantage. The bus room is jointed in FT8-12 vacuum load switch h +fuse composite electric apparatus. The load switch room and bus room is separated by metal boards. This structure has the advantage of being free of insulating plates and the interlock devices over other RMU. The fixed RMU, which is fitted in VT2A type vacuum breaker is used to protect the circuit, it is a supplement of primary wiring scheme of RMU.
Features
a. Busbar room of RMU and cable room are divided into two rooms with the metal chassis of load switch. it’s no need to insert one insulating barrier in isolating distance.
b. Vacuum arc-extinguishing chamber is located in the insulation bushing to prevent dust accumulating on the surface and arc-extinguishing chamber from damage of unexpected external force.
c. Live parts of load switch on each phase is supported by single insulation bushing, therefore the structure is simple and compact.
d. The interlock is reliable and it is convenient to operate.
e. Possess manual and motor-driven operation and small operating force.
f. Operate disconnector and earthing switch through the same hole.
g. Multiple schemes for choice, convenient for RMU extension and combination, income and outgoing line cabinet can be circuit breaker cabinet with protection function.
h.RMU can be mounted against wall.
i. The RMU frame is assembled by zinc plate coated with aluminum, the volume is 600*1750* 900.
