High Voltage Testers are specially designed for testing cables and Electrical Equipment as per IS/ IEC specifications. Each unit is tested at various stages, for maintaining quality. These instruments are air cooled, as well as air & oil cooled combined.
Special Features
Brief Technical Detail
Transformer: A double wound step up transformer is the most important part. The transformer is wound with high quality enameled copper wire and polyester film/paper is provided between the layers. C.R.G.O. strip core are used for light weight & efficient transformer.
