CGVD 1/40.5
Wukai
1. Product Description
CGVD series product is an electromagnetic gas-insulated voltage transformer designed for AIS substation. The iron core and winding are located at the bottom of the product, and it is a vertical structure. The low-design magnetic flux density and special core structure of the transformer core can effectively reduce the possibility of ferromagnetic resonance in the product. The interior can be filled with SF6 or various environmentally friendly gases for insulation, with a lightweight structure, excellent seismic performance, and simple transportation and installation.
