Hangzhou Yunguang Power Line Equipment Factory has more than 40 years' history. As a mature power line equipment factory, we have complete ability of chemical analysis, mechanical testing and Kim Sang-analysis testing as well as infrastructure and technology strength. We mainly produce power line equipment of casting, stamping, and plating. Especially in the hot-dip galvanizing technology, due to using multi-rare earth alloy plating technology, we significantly level up the products' brightness of coating and corrosion resistance. Through the testing by Wuhan Institute of Material Protection, it proved that the rate of coating and corrosion resistance is twice high as normal ones. Our major products are hanging clips, resistant clips, united links, protection equipment, and hundreds of other products. Our factory is a major producer of power line equipment in Hangzhou.
