Gas insulated Transformer System

YDSW Series

[Gas Insulated Transformer System]

SF6 insulated Test Transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and in the field, and for testing the other substation equipment. It is also the portable and easy maintenance solution. The SF6 test transformers can be flanged directly to the GIS for testing which make the partial discharge test easy and quick. These systems are particularly suited for on-site tests of GIS after installation. In the factory, they are used to test sub-assemblies and components directly in the manufacturing line.
