KYN61-40.5 (Z) - type suit with blocks of metal exchange closed at the beginning
KYN61-40.5 (Z) - type suit with blocks of metal exchange closed at the beginning (hereinafter referred to as opening cabinets) is the exchange of three-phase 50Hz, rated voltage of 40.5kV indoor sets distribution devices. As power plants, transformer stations and distribution of electricity and the mining industry accepted by the circuit a control, protection and monitoring, and other functions, can also be used to frequent the establishments operate the switches at the GB/T11022-1999, GB3906-1991 and DL404-1997 standards.
ZW8-12 series outdoor vacuum circuit breakers
¡¡¡¡ZW8-12 exchange 50Hz three-phase series of outdoor vacuum circuit breakers, and the outdoor 12kV high voltage power distribution equipment, as a sub, and the load current, overload and short-circuit currents current use. If the same computer system and remote data terminals and other equipment with wireless transmission lines linking China can achieve remote hours, and the switches function, urban power grids, oil, the transformation of agricultural materials grid without the best equipment KYN61-40.5 (Z) - type suit with blocks of metal exchange closed at the beginning Main features 1. Juti structure used assembled, circuit breakers used wooden landing-style structure; 2. With a new type of composite insulation vacuum circuit breakers, and there are good simple interchangeability of characteristics; 3. Wooden chassis, equipped with Sigang nut institutional, relaxed movement wooden, and to prevent damage to the structure and Wucaozuo; 4. All operations can be carried out in transparent closed; 5. The switches, wooden, switches between the chain lockers are used mandatory mechanical locking methods to meet the "5 -" function; 6. Cable ample room space, connecting more roots cables; 7. Rapid and earth switches for earthing circuit short circuit; 8. External protective levels IP3X, wooden room doors open situations, protective levels IP2X; 9. Products meet GB3906-1991, DL404-1997 and in the light of the adoption of international 1EC-298 standards. Use of environmental conditions Environmental temperature : ceiling +40 degrees and the average may not exceed 24h detect 35t, floor -10 'C, Altitude : the altitude of no more than {000m. Relative Humidity : Japan averages less than 95% on average does not exceed 90%. Seismic intensity : no more than eight degrees. Water vapour pressure : Japan averages less than 2.2kPa, on average less than 1.8kPa. No fire, explosion hazard, serious filthy, chemical corrosion and intense vibration platform.
