Isolater Switch /Knife Switch FGW9 Series

Isolater switch /Knif switch  which a switching device mainly used for “isolated power supply, reverse operation, to connect and cut off small current circuits”. When the disconnector is in a subposition, there is an insulation distance and a clear disconnection mark between the contacts that meet the specified requirements; A switchgear that can carry current under normal loop conditions and current under abnormal conditions (such as short circuit) within a specified period of time. Generally used as a high-voltage disconnector, that is, a disconnector with a rated voltage of more than 1kV, its own working principle and structure are relatively simple, but due to the large amount of use, high requirements for work reliability, the design, establishment and safe operation of substations and power plants have a greater impact.

Knife switch/isolator switch Polymer have CNAS Certification,Zhejiang Zhongyi supplied voltage between 10 and 36kv. More information can find in Zhongyi.
