Electrical switchgear
Type ZF10-126/T2500-31.5 small gas-insulated metal-enclosed switchgear is designed to meet the demand for upgrading power grid of urban and rural area during the Ninth Five-year plan period after 1997. After absorbing the advanced GIS and GCS technology from home and abroad, it has accomplished the optimization design. In 1999, Dazheng completed the full set of type tests,In 2001, Dazheng won"Leading New Product Certificate" which was awarded by State Economic and Trade Commission, In 2002, Dazheng obtained 2ndTechnology Prize of State Machinery Industry, In 2003, Dazheng won the 2nd price for scientific and technological progress of Shaanxi province.

Technical Characteristics
1,Compact Size, Light Weight
   Compact design, the minimum clearance is 1.2M, occupy a small space
   The outer shell adopts aluminum alloy material which is anti-corrosion and light in weight. The standard interval weight is less than 3t.
2,Low operating power, Excellent breaking capability
Adopting the principle of self-energized arc extinction, the short circuiter has excellent breaking capability, the breaking frequency under full capacity can reach to 20 times.
   The self-energized arc extinguishing breaking operation costs only one quarter of compressed air circuit breaker, low operating power and high reliability.
3, Low inflation pressure; High insulation level
  Split phase structure, uniform electric field, accurate electric field analysis and calculation to internal conductor and insulator, the overall insulation level has surpassed the regulations of state standard and IEC standard.
4, Modularization of element design
The modularization of element design is applicable to the layout of various substations, it also has greatly diminished the cycle of design and construction.
5, Complete partition transport, short installation cycle
Tests have been conducted to those transportation units in the factory, so as to ensure the on-site product quality and diminish the on-site maintenance period as well.
6, Light weight, Convenient for transportation
Note,Reverse polarity pressurization
