24kV 1250A Epoxy Resin Insulation Solid-Sealed Electronic Type Vacuum Circuit Breaker

      24kV 1250A High voltage epoxy resin solid-sealed pole vacuum interrupter embedded poles for vacuum circuit breaker

The vacuum interruptor and the circuit-breaker related conductive parts are simultaneously embedded into the solid insulating material such as epoxy resin or thermoplastic material, which is easy to solidify, to form a pole, so that the entire circuit breaker pole becomes An integral part. This type of costing resin vacuum interrupter is epoxy envelope, silicon liquid latex and Cu-Cr contact holder adoping axial magnetic field intended to install in the accordant indoor and outdoor vacuum circuit-breaker or other vacuum distribution devices. It is especially used in the electric power, mechanical, chemical and metallurgical departments as well as mines and other industrial departments where it is operated frequently. The small sized interrupter is noted for its conpact design, large switching capacity and high insulating level.

Features

• Modular design, simple structure, few detachable parts, and high reliability;
• Extremely high insulation rod capacity. It turns surface insulation into volume insulation, which reduces the impact of the environment and greatly improves the insulation strength compared to air insulation.
• It can reduce the size of the circuit breaker, which is conducive to the miniaturization of the switch cabinet.
• Compared with the traditional assembled pole, the number of parts of the solid-sealed pole is greatly reduced, the overlapping surface of the conductor is reduced from 6 groups to 3 groups, and the connecting bolts are reduced from 8 to 1~3.
• A simple structure greatly improves the reliability of the circuit breaker; because the vacuum interrupter is embedded in the solid material, no further treatment is required, and the solid-sealed pole can achieve high insulation strength; After the arc chamber is embedded in the solid material, the influence of the external environment of the pole post on the vacuum interrupter is minimized.

COMPANY OVERVIEW

    Xian Xiwuer Electronic & Info. Co., Ltd. is located in Beiguan, Xi'an city cover in an area of 4000 ㎡, with employees of 2300, and about 580 technicians, amongthem, there are 135 engineers, 21 senior engineers. The company has total assets of 315 million RMB Yuan, fixed assets of 137 million RMB Yuan, which is a large enterprise mainly engaged in producing electronic components. The company has the largest production scale of Varistor,SPD( Surge Protective Device)and HV Ceramic Capacitor in China, with the following main products :

1. Varistors & SPD

4. Thermistor

       The main production line and inspection equipment & instrument are imported from Japan, America, Belgium and Switzerland etc. The annual production capacity of the two leading products has been reached to 5 million pcs and 150 million pcs respectively, with the market holding rate in China of about 10% and 30% respectively by continually technical innovation. Varistors and SPD produced by the company enjoyed great reputation in the international market, being exported to many countries and areas such as Japan,USA, Hong Kong etc., with the customers like India and GE in USA. are already sold to LG company in Korea with large quantity, and also to Spainand India etc.

       Not only the products quality and technical capacity, but also the completeness of the models are all in the leading place in China. The main products have got CCEE, UL, VDE & TUV approval. The quality system was set up according to the requirement of ISO9000 since 1992, and has passed ISO9002 approval by DNV International Organization in July 1994, then got ISO9001 certification by British organization in 2000, by then we are both the first one who are approved by ISO9000 certification in the North-west area of China and the same occupation. We passed all the successive periodical audit and smoothly get the new certificate registered in Holland in Aug.1997; the quality system is strengthened and completed constantly. And we also got ISO18000 certificate.

      We believe we are able to supply satisfied goods and service to customers home and abroad with the most reasonable price and the shortest delivery time, on basis of our excellent quality assurance capacity, technical development capacity and rich manufacturing experiences.
