2. Product Features

1. Ultra-high energy efficiency, reduced costs and increased effectiveness

   It utilizes high-quality silicon steel sheets, oxygen-free copper windings, and an optimized electromagnetic design. No-load and full-load losses are significantly lower than national standards, significantly reducing long-term operating costs. The additional investment can be recovered within 3–5 years.

   Voltage regulation under load, stable voltage

   It adapts to new fluctuations in power load and precise loads, ensuring high quality of power supply.

2. High reliability, high impact resistance

   Reinforced winding with uniform ampere distribution, excellent short-circuit and lightning surge resistance. Hermetically sealed oil tank, low partial discharge (≤ 50 ps), hermetically sealed design, suitable for harsh environments.

3. Low noise level and eco-friendliness

   Adopts a stepped core with hardening treatment, the noise level exceeds national standards. Hermetic seal reduces oil pollution;Low-loss designcontributes to achieving carbon peaks and carbon neutrality goals.

4. Intelligent operation and maintenance; low operating and maintenance costs.

   Standard monitoring of oil temperature, oil level, gas relay, and winding temperature, supporting remote monitoring. The hermetically sealed design eliminates the need for frequent oil refills and eliminates long maintenance periods.

3. Application scenarios
