HXGN□-12Z
the case type( regular) exchanges the metal and seals
the ring network cupboard of vacuum( hereafter referred
to as the vacuum ring network cupboard of high pressure)
development is asked to combine our country and supply
power, The equipment of electric apparatus of new-type
high pressure that was jointly produced by our company
and Guangdong Zhu Jiang River switch Co., Ltd., Performance
reach IEC298"Exchange the metal and seal the switchgear
and control the equipment"and GB3906"3-35KV
Exchange the metal and seal the switchgear"standard.
It has filled in the domestic blank, adopts the module
to design.The volume is small（width 850mm×2000mm×1000mm）can
frequently operate, time between overhauls(TBO) is long,
install it conveniently,reach the present international
similar products level.
Suitable for the small-scale transformer
substation three times, turn on and close specifieds voltage
of three-phase, such as, wind power station, factories
and mines, housing district, skyscraper, school, park,etc.
10 KVs, In the distribution systems of 50 Hzs of frequency.It
is as accepting and it assign electric energy with,use
in supply power at terminal stations for networks for
ring . |
