In 33kV/35kV high-voltage outdoor distribution systems, voltage transformers (PTs) are core equipment for energy metering, voltage monitoring, and relay protection, directly affecting the accuracy of electricity billing and rapid clearing of grid faults. They must have extremely high measurement accuracy, long-term stability, and strong environmental adaptability to cope with global complex climate challenges including high temperature, high humidity, 鹽霧, heavy pollution, and high altitude. Traditional PTs often suffer from oil leakage, rapid oil aging, accuracy drift, and high pollution flashover risk, which are difficult to meet the harsh requirements of outdoor high-voltage scenarios.

The 33kV/35kV oil-immersed outdoor voltage transformer (PT) specifically addresses the above pain points, tailored for medium and high-voltage outdoor scenarios, with dual voltage compatibility for 33kV and 35kV. Core advantages are as follows:

1. Dual Voltage & Multi-Accuracy：Compatible with 33kV (36kV insulation level) and 35kV (40.5kV insulation level); Class 0.2 高精度計量, Class 0.5 general metering, Class 1 monitoring, Class 6P relay protection, selectable on demand
2. Core Function：Steps down 33/35kV high voltage to 100V/√3 or 100V standard secondary voltage; JDJJ2 series with residual winding (100/3V) for earth fault protection; Strictly prohibited from short-circuit, must be protected by fuses; Hermetic seal prevents oil leakage and moisture ingress
3. Reliable Structure：Three-limb silicon steel core with low loss; Oxygen-free copper windings with vacuum oil impregnation; Oil tank equipped with oil level indicator, drain valve, and grounding bolt; Anti-pollution porcelain/composite silicone rubber bushings with sufficient creepage distance, 防污閃, 耐鹽霧性, 抗紫外線
