JDZ(X)W-17.5（24） Outdoor Voltage Transformer

Product Overview

JDZXW-17.5（24）voltage transformer, outdoor epoxy resin casting and full-enclosed construction, is widely used for measuring current, electric energy and protective relaying in the single-phase or three phase power system with the frequency 50Hz or 60Hz and highest voltage for equipment 17.5kV or 24kV 

Key Features

• Dual Voltage Rating Compatibility Design：Supports both 17.5kV and 24kV rated voltages simultaneously, adapting to grid requirements in different regions. It offers broader applicability and flexibility, providing one-stop solutions for multi-voltage outdoor substations.

• Fully Sealed Moisture-proof Structure：Adopts epoxy resin vacuum casting fully sealed process with IP67 protection rating, effectively resisting harsh environments like moisture, salt fog, and dust. It ensures no internal moisture risk during long-term outdoor operation, eliminating the need for regular maintenance.

• High-precision Measurement Performance：With voltage ratio error ≤0.2% and phase difference ≤10', it meets the 0.2-class metering accuracy requirement, providing precise voltage signals for energy metering devices and relay protection systems to ensure reliable power data collection.

• Wide Temperature Range Stability：Operates within -40℃~+70℃, using low-temperature resistant epoxy resin and high-temperature insulation materials. It maintains stable electrical performance in extreme temperatures, avoiding insulation aging caused by thermal expansion and contraction.
