Overview of JDZXFW-35 Voltage Transformer

The JDZXW-35, JDZXFW-35kv voltage transformer is an outdoor epoxy resin-cast, fully enclosed device designed for 35kV power systems. Operating at a rated frequency of 50Hz or 60Hz, it is used for energy metering, voltage monitoring, and relay protection. It features secondary winding outputs of 100/√3V for energy measurement and 100/3V for residual voltage, with a triangular configuration to protect relays during grounding faults. Built to withstand external short circuits for 1 second without damage, it offers excellent durability, with resistance to arc faults, UV exposure, and aging, making it ideal for reliable performance in outdoor medium-voltage applications.
