JW5-550/363 type Disconnector
Brief Description
The outdoor high voltage earthing switch produced by our company has a variety of voltage levels of 40.5～550KV, not only can be used as the earthing switch of busbar, but can be netural point earthing switch of transformer. The structure of the product is advanced, the electrical performance and mechanical performance are stable and reliable, and meet the requirements of GB1985-89, IEC-129 (1984) and related technical conditions. By the widely use of products by the majority of users and the continuous improvement and development during the past years, the earthing switch produced by our company have become China’s power industry’s preferred products.
