Structure and Feature
The Voltage Transformer is of post type. Its hermetically sealed by epoxy resin, with design advantages of anti-pollution, anti-damp, easy to be installed is also suitable for tropic area and free from special maintenace except periodically surface clean. Secondary outlet terminal is equipped with connection terminal box. Upside and profile of the box have a hole respectively. The two holes together with outlet terminal are for leading out. Six holes at the bottom of the PT are suitable for mounting.
