Technical parameters:

Dandong Power Equipment Co.,LTD was established in 1988, which is a professional factory to produce the high-voltage productions in Liaoning province. State Economic and Trade Commission recommended it as the factory that provides to projects for upgrading urban and rural power grids. It also earned the bidding of electricity in the 2008 Beijing Olympics. Factory has passed the ISO9001 Quality Management System Certification in 1999, and also finished the 2000 concert in 2002.
The factory is located in Dandong---the biggest border city, the floor space of 12000 square meters. The area of structures cover about 5000 square meters. Total assets are almost 4.5million dollars. The workers' educational background in it is greater than the 60% graduated from college and technical secondary school with high qualified title. Our factory is good at mechanical, advanced training facilities and management. And the mainly products are circuit breaker, fuse and switch.
Factory contributes on preparing for the high-tech products to suitable power system. We have developed about 12 series, hundreds of type of high-voltage products. ZW16-12 Type and ZW32-12 Type are outdoor vacuum circuit breaker. LW3-12 Type sulfur hexafluoride circuit breaker is based on the analyzing way of exterior structural feature, and then based on analyzing the Congeneric Products of inland. Utilising the operating mechanism and turnkey design of ourselves that allow us to exploit, which leads this field in China. GW39-12 Type outdoor switches disconnecting use the horizontal turning and the supporting insulator produced from insulating material of silicone rubber. BRW series fuse is the top selling in China. We also get rid of the Rw11-12/HRW11-12 types high voltage outdoor extreme fuse and HY 5WS-17/50 Metal-oxide Surge Arrester, some other high/low voltage GW9/DJW and so on.
Factory combines with the feature of the country and towns' power grid. We also design for the XJD1-WF type low tension reactive power compensation. All of the high voltage power compensation use Microcomputer Technology to control capacitor. It not only saves power and increases the power supply quality, but also data storage and wireless data transmission and some other functions. It is quite popular with customers.
The company produces each kind of high voltage product which is very fine in quality, many times obtains the title of honor, like "scientific and technological progress to advanced enterprise". In January, 2000, Our Company was reorganizesd as the joint stock cooperative system. After that, we acquired world-class talent, and being the creative factory with the high-quality products. So, we improve the customers' trust and bring first-class service and products. We hope we can get a long-term relationship with you and your company in sincerity.
