Product Description

JDQX-110(220)type high voltage transformer

Product Overview

JDQX-110(220)series of voltage transformer is outdoor phase-to-earth SF6 single-phase voltage transformer with four windings. It is equipped for the effective earthing system at the neutral point for the functions of voltage and energy measurement and relay protection. It meets the requirements of GB1207-2006 Voltage Transformers and GB311.1-1997 Insulation Co-ordination for High Voltage Transmission and Distribution Equipment. This product is comprised of tank body, transformer body and porcelain bushing. The transformer body is placed in the tank at the lower part of the product. The internal body is filled with SF6 gas. Fine sealing between each connection prevents gas leakage. It is featured with the advantages of impact structure, fine insulation performance, uniform field distribution, low partial discharge, high sealing performance, long using life, simple maintenance and safe operation.
