EVS160-630A Heavy Task Low-voltage Vacuum Contactor

The series EVS 160-630 of heavy task low-voltage vacuum contactor is produced with the technology and key equipment introduced from abroad by our company. This product has met IEC, VDE technical standards. This series of vacuum contactors have such advantages as high capabilities of switch-on and switch-off, long electrical and mechanical lifetimes and high operating reliability under the bad conditions.

They are especially suitable for being used in the basic industries, metallurgical, petrol-chemical industries, mine and wharf. It is applicable to the power system with 50Hz/60Hz alternating current, rated operating voltage up to 1140V, rated operating current up to 630A to switch-on or off the circuit at a short or long-distance, to start frequently and control alternating motor under the heavy task and to form electro-magnet starter with other kinds of protective devices.

Founded in 1958, Guoguang Electric Co., Ltd. Chengdu. is one of the Soviet Union's aids 156 key projects during the 1^st Five-Year plan, and also a comprehensive factory dedicated in manufacturing of microwave electron. In October of 2000, the factory is reorganized into a share-holding corporation that set foot in science research, manufacturing and trading. The headquarter and the manufacturing base are situated in the state-level economic and technological development zone of Longquanyi District, Chengdu city. The manufacturing base area is 133,340m² and the total area of structure is 80,000m². The total asset of the company is nearly 900 million RMB and net asset is 600 million RMB. Over 1100 staff members have been employed and over 30% of them are medium and high ranking technicians.

The main business scope of the company is: Research and production for all kinds of microwave electron vacuum parts, solid microwave devices and microwave encapsulation, vacuum contactor and breaker, vacuum chamber, switch gear, aircraft kitchen appliance(including train meal-trolley) , exhaust carts, all kinds of non-standard machinery and electrical equipment, vacuum gauge, vacuum measurement instruments, appliance of microwave energy, microwave source, medical laser appliances, etc. The products have been sold as far as overseas market and achieved great contributions for the national defense and scientific research work.

The company has been attaching much importance to the development of technology and equipment renewal since its establishment. To guarantee the production, the company has introduced much advanced equipment from U.S., France, Austria, Italy, Germany, etc. Our company has a complete internal matching capacity, besides the developing and researching of components, devices and overall unit, we can do raw material analysis, precision component processing, ceramic manufacturing and sealing, cathode manufacturing, surface treating, reliability and environment test.
