III. Main Features
1. High Efficiency and Energy Saving — Absolute Energy Saving
. Long-term energy costs and ensuring a quick return on investment.
2. Without
Maintenance The corrugated oil tank seals out air and moisture, preventing aging of the insulation oil and ensuring lifetime replacement and maintenance-free operation.
3. Strong resistance
Short circuit resistance: Full copper windings, optimized ampere distribution and robust design ensure high short circuit resistance and stable operation.
4. Low noise and low vibration
The multi-stage peer core design and anti-attenuation design effectively reduce noise and vibration, which is suitable for residential areas, schools and hospitals.
5. Excellent overload and adaptability to
environment. Optimized cooling of oil channels allows for short-term operation under overload conditions. Suitable for outdoor installations, pole-mounted systems, and box-type substations, adapting to high and low temperatures, humidity, and dusty environments.
6. Safe, reliable and long lasting
Service. Equipped with pressure relief valves, temperature control, and gas protection, ensuring high operational safety and slow insulation aging for a longer service life.
