JDZ10-12QC Voltage Transformer

Product Overview

12kV Indoor Single-Phase Epoxy Resin Type Epoxy resin casting and double pole insulated fully enclosed construction, is used indoor for measuring  , electric energy and protective relaying in the electric system with the frequency 50Hz or 60Hz and highest voltage for equipment 7.2/12kV. The product has the feature of high reliability, low magnetism of core, large creepage distance of external insulation and maintenance free etc.

Feature

• High-precision Single-phase Voltage Conversion: Specifically designed for 12kV single-phase systems, using high-permeability silicon steel cores and precision windings. With a metering accuracy of 0.2 class and stable voltage ratio, it ensures accurate and reliable metering and monitoring data.

• Enhanced Indoor Environment Adaptability: Fully enclosed epoxy resin casting structure effectively isolates dust and moisture, enabling long-term stable operation in indoor environments with temperatures from -5℃ to 40℃ and relative humidity ≤90%, suitable for enclosed spaces like switch cabinets.

• Highly Reliable Insulation Performance: The insulation layer has excellent mechanical strength, withstanding 12kV rated voltage and operational overvoltage impacts. Partial discharge ≤10pC significantly reduces insulation aging risks and extends equipment service life.

• Compact Design for Improved Installation Flexibility: Optimized volume supports horizontal/vertical installation, fitting narrow spaces. Standardized dimensions reduce installation difficulty, saving time and costs.

• Convenient Operation & Maintenance Features: Flexible outlet options (direct outlet/cable connection), no complex debugging required for daily maintenance, strong anti-electromagnetic interference capability, ensuring long-term stable operation and reducing maintenance burden.
