  • Company Profile

●Brief Description   ZFN13-40.5(Z) Indoor GIS, which is the new type product researched and developed independently by us, fills the domestic gap of 40.5kV GIS and meets the standards of GB1984, GB3906, DL404 and IEC-298 etc. This type applies to the indoor power system of three-phase a.c rated frequency 50Hz and rated voltage 40.5kV, and is used for switching off the load current, overload current and fault current; transforming and isolating line; measuring the voltage and current; protecting overvoltage etc. ZFN13-40.5(Z) GIS is especially fit for the places such as city subway, light rail, high-rise building and key subscriber.

 ●Main Features

  1 ZFN13-40.5(Z) GIS is metal-enclosed and metal-armoured , with SF6 gas as the insulating medium. The three-pole layout is longitudinal.

  2 The circuit breaker adopts the vacuum interrupter with spring mechanism, which is suitable for frequent operation.

  3 Using the 3 -position switch as busbar disconnector and feeder earthing switch connected with circuit breaker through reliable mechanical and electric interlocks.

  4 Application of intelligent module meets the requirements of market.
