JDZ11-12A 12kV Indoor Single-Phase Voltage Transformer

Product Overview

12kV Indoor Single-Phase Epoxy Resin Type Epoxy resin casting and fully enclosed construction, is  used indoor for measuring  , electric energy and protective relaying the electric system with the frequency 50Hz or 60Hz and highest voltage for equipment 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: Compatible with 12kV single-phase systems, using high-permeability cold-rolled 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 for single-phase circuits.

• Enhanced Indoor Environment Adaptability: Features a fully enclosed epoxy resin casting structure, effectively isolating dust and moisture. It can operate stably for a long time in indoor environments with temperatures ranging from -5℃ to 40℃ and relative humidity ≤90%, suitable for enclosed spaces such as switch cabinets and substations.

• Highly Reliable Insulation Protection: The insulation layer has excellent mechanical strength, capable of withstanding 12kV rated voltage and operational overvoltage impacts. With partial discharge ≤10pC, it significantly reduces the risk of insulation aging and extends the safe operation life of the equipment.

• Compact Design for Easy Installation: Its volume is reduced by more than 20% compared to traditional products. The lightweight structure supports horizontal/vertical multi-directional installation, saving indoor space and reducing installation labor and time costs.

• Convenient Operation and Maintenance Features: Complies with standardized installation dimensions and offers flexible outlet methods (direct outlet/cable connection). Daily maintenance requires no complex debugging, allowing quick integration into existing systems and improving power operation and maintenance efficiency.
