High Voltage GIS Gas Insulated Electrical Switchgear Sf6 Insulated ,HXGT Series with 35 ~ 40.5KV
High Voltage GIS Gas Insulated Electrical Switchgear Sf6 Insulated ,HXGT Series with 35~40.5KV
Product Overview:
HXGT10 (XN65)-40.5Z Switchgear is a composite apparatus which seals all main circuit switchesabd wires in the metal enclosure and uses SF6 gas as arc-extinguishing and insulating medium. It is suitable for RMU and double radiation power supply in 40.5kV power supply circuit, which can change the original way of single radiation power supply. When circuit failure happens, it can restore the circuit feed of the transformer in time, which greatly improves the reliability and utilization factor of power supply. The product is especially suitable for industrial and commercial zones or rural area, which have high-density power supply load and use cable feed network. Meanwhile, RMU has the advantages of safe operation, no weather influence, easy installation, little maintenance and space saving, which is suitable to be installed in box-type substation and inside tower of wind turbines. RMU can be combined flexibly by the extension of busbar.
Features:
a. Equipped with load switch, load switch +fuse composite apparatus and circuit breaker function unit, its function is very complete.
b. It has multi-function common box type and external busbar extension type for choice , it can realize flexible combination of multiple scheme.
c. Small volume, low weight, minimum volume for one single is 500*1000*1750(mm). It is convenient for transportation, carry and installation.
d. It is suitable for the place which has high demand on space, such as wind generator tower.
e. Easy operation, safe using, convenient maintenance, the switchgear can service for 30 years without maintenance.
f. The switchgear is designed to be omniseal without exposed live part and can run for a long time in the severe environment.
