1.Main Features
1. 1 Type GW27-1100 is the first 1100kV high voltage alternating disconnector in China, which is researched on our company’ own, and we have the complete knowledge property right.
1.2 The electric connection’ rotating construction has been granted national practical new-type patent, reached to advanced level of the same products in China.
1.3 The products have stable and reliable action, small operating forces, high technical data, long mechanical life and good antiseptic performance, etc.
GW27-1100 Disconnectors have been passed serial tests, such as capacity and insulation tests, in KEMA and in Wuhan High Voltage Electric institute.
