Specifications
?On our nation 40.5Kv transmission line, there is
still massive adoption of various fuses. For the terminal station
especially,because of its low rated current and rated
short-circuit current,like "waste one's talent on a petty
job" , far from
economy.
?Overseas, load switch or load switch and fuse
composed electric apparatus are widely adopted for its economy, convenience ,safety, and dependability. While
for our country, so far, no SF6 load switch is available on 40.5kV voltage degree.
The only choice is using 36kV air load switch from other country, but its
insulation level doesn't meet our nation standard,it still unsuited for the running on our nation
grid.
?For the above reasons,we developed XGN65-40.5 Indoor HV
SF6 Ring main unit.
