ZFCC5-7.2(12) Combination of High Voltage Vacuum Contactor & Fuse

ZFCC5 serial is a combination of AC High Voltage Vacuum Contactor and Fuse. It features for the industrial control system that frequency: 50Hz, rated voltage: 12kV(7.2kV), rated current: 225A Max. (for 7.2kV: 315A Max.). It can be matched with switchgear to built F-C circuit, be used together with general protection. It can control and protect high voltage motor, transformer and capacitor bank.

Products design:

1. ZFCC5 is a F-C combination of JCZ5 Vacuum Contactor and High Voltage Current Limiting Fuse by series. The control function is realized by JCZ5 Vacuum Contactor and the protection function is realized by High Voltage Current Limiting Fuse.

2. ZFCC5 use VSI (ZN63A) breaker base cart as the swing bar structure. It has the compact structure, and its dimension is matched with KYN28 high voltage gear.

Five Protection use the reliable lock structure, can be avoided the below mentioned electrical wrong operation:

1. When the contactor is opened, the cart can be moved.

2. When the cart is in operation position or break test position, the contactor can be closed.

3. The contactor is in the close position, whenever the cart is in the operation or test position, the cart can not be moved.

Main technical data:

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.
