Medium Voltage Outdoor Resin Cast Current Transformer
Medium Voltage Outdoor Resin Cast Current Transformers of single core for metering purpose are commonly used. Di-electric strength of the oil-impregnated paper insulation is preserved by hermetic sealing of the transformer.
Resin Cast Outdoor Current Transformer
A current transformer so arranged that it act as a support for the conductor in the primary circuit. These transformers are of compact design with high mechanical and electrical properties.
