JDZ11-36 36kV Indoor voltage transformer JDZ11-36 36kV Indoor na voltage transformer

Product Overview

36kV Indoor Single-Phase Epoxy Resin Type JDZ11-36 voltage transformer, is fully enclosed casting insulation structure, the primary winding, secondary winding and the annular core all coating in the epoxy resin casting, improve the filth and moisture resistance. The model adds the umbrella skin product design and increase external insulation creepage distance, is widely used indoor for measuring current, electric energy and protective relaying in the isolated neutral system with the frequency 50-60Hz and highest voltage for equipment 40.5 kV.

Feature：

• High-Precision Voltage Conversion: Uses high-quality silicon steel sheets and winding materials, with accurate voltage ratio and metering accuracy up to class 0.2, ensuring the accuracy of energy metering and monitoring data to meet the high-precision measurement needs of the power grid.

• Compact Structural Design: Optimized for indoor spaces, its volume is 30% smaller than traditional similar products, saving substation floor space and suitable for installation in compact environments such as switch cabinets.

• Excellent Insulation Reliability: Fully sealed with epoxy resin casting, reaching IP67 protection level, effectively resisting moisture, dust and dirt, and can operate stably for a long time in environments with relative humidity ≤95%.

• Upgraded Safety Performance: Built-in overvoltage protection device, capable of withstanding 40kV lightning impulse voltage to prevent damage to equipment from system failures; partial discharge ≤10pC, reducing the risk of insulation aging.

• Convenient Installation and Maintenance: With bottom outlet design, supporting horizontal or vertical installation, and self-contained mounting holes, it can be fixed with 4 M12 bolts, reducing on-site construction time by more than 50%.
