    GW4 Series outdoor HV Disconnector is our products developed on basis of many years’ experience. The contact fingers of DS adopt “self-pressure” structure. Earthing switch adopts rotary positioning structure and this decreases the horizontal impact to porcelain post during switching on. This structure makes the conductive capability safer and more reliable. Semi-closed structure of transmission system keeps the transmission joints free from being affected directly by environment and ice-coating. Thus it greatly increases the anti-ice and snow ability. Interphase drive transmission resorts to rotation mode, which eliminates non-synchronization of three phases caused by temperature.
    The technical performance of 40.5kV to 252kV disconnectors has reached the advanced level of domestic similar products.
