As a special ancillary product of arrester, disconnector is series connected with arrester, coming into work rapidly when arrester break down, throwing failure arrester out of electric network and giving obvious disconnecting sign, which makes it's easy for maintenance people to find fault point and replace the failed arrester. On the other hand, when arrester is correctly working, disconnector will be out of work, low-resistance, and has no influence of arrester's protection property. Arrester configured with disconnector is truly realizing the property of safety, free maintenance, convenient and reliable. Disconnectors are generally used in arresters in advanced countries such as European, USA, Japan and other countries.
Our disconnectors with newly thermal-explosive design, quick response and no mistakes at working, can match with all kinds of 3kV or above arrester. Working conditions are same as arrester.Installation size:
