General:
XGN56-12 (XGT3-12) Cubicle Fixed AC Metal-clad Switchgear (following abbreviation switchgear) is a lastest version of high voltage electrical complete set of equipment which designed and developed by self, it fits national standard GB3906 " 3-35kV's AC metal switchgear" and power ministry requirement of DL 404 "indoor AC HV switchgear's technology requirement of order", and also satisfied requirement of international standard IEC 298 " AC metal sealed switchgear and control equipment which rated voltage is 1kV to 52kV", and possesses the ability of " five guards against" required by two ministries.
This product has absorbed the advanced technology of abroad, and design and develop by self according to the question of higher accident rate in running and large volume at present the same's switchgear of our country occurs, and it posses the merits of small volume, only 50% with ordinary switchgear volume, high reliability, good capability, "five guards against" interlocking mechanism is reliable and simple etc.
Application:
The switchgear is suitable in indoor complete set of device which 3.6~12kV three-phase AC 50Hz single-bus burst, it used as electric energy accepting and distributing and possess the merit of control and protects and monitoring to the circuit etc. It can be used in all kinds of power plant and power station industrial and mining enterprises, high-rise building, etc. And can also be used in open and close place with RMU.
