30kV Metal-Clad Potential Transformer for Indoor Application

Medium-Voltage Potential Transformers (30~36 kV)


About the Product

Designed for the switchgear panels of a 36kV (max.) power system, this single-pole indoor-use potential transformer is cast in Araldite® epoxy resin and covered with an aluminum box. The grounded aluminum box for shielding reduces the necessary distance between the potential transformer and the panels (or other equipment). This epoxy-cast potential transformer is characterized by excellent moisture resistance, superior electrical performance, and great reliability.
