ZFN13-40.5(Z) GIS
Inquire NowDescription
The ZFN13-40.5(Z) Indoor GIS is a cutting-edge solution developed to meet the demanding standards of GB1984, GB3906, DL404, and IEC-298. This innovative gas-insulated switchgear (GIS) operates at a rated voltage of 40.5 kV and is ideal for three-phase a.c. power systems at 50Hz frequency. It is designed to efficiently manage load currents, overloads, and fault currents, while also enabling voltage and current measurements and overvoltage protection. Perfectly suited for urban infrastructure such as subways, light rail systems, high-rise buildings, and critical subscriber installations, the ZFN13-40.5(Z) GIS is equipped with advanced features that enhance its reliability and performance.
Main Features:
- Metal-enclosed and metal-armoured design utilizing SF6 gas as an insulating medium with a longitudinal three-pole layout.
- Vacuum interrupter circuit breaker with a spring mechanism, allowing for frequent operations.
- 3-position switch functioning as a busbar disconnector and feeder earthing switch, featuring robust mechanical and electric interlocks.
- Incorporation of an intelligent module to meet modern market demands.
