III. Main features
1. High efficiency and energy saving — Absolute energy saving
. Long-term electricity costs and ensuring a quick return on investment.
2. Maintenance-free
Corrugated oil tank isolates air and moisture, preventing aging of insulating oil and ensuring lifetime replacement and maintenance-free operation.
3. Strong short-circuit
resistance: Full copper windings, optimized ampere-turn distribution, and robust construction ensure high short-circuit resistance and stable operation.
4. Low noise and low vibration
Multi-step core design and anti-loosening structure effectively reduce noise and vibration, suitable for residential areas, schools, and hospitals.
5. Excellent overload capacity and adaptability to
environment. Optimized cooling of oil channels allows short-term operation under overload. Suitable for outdoor installation, pole-mounted systems, and box-type substations, adapting to high and low temperatures, humidity, and dusty environments.
6. Safe, reliable, and long service
life. Equipped with pressure relief valves, temperature control, and gas protection, ensuring high operational safety and slow insulation aging for a longer service life.
