Intermediate transformer
1. High efficiency and energy saving: Low energy loss design that meets the latest energy efficiency standards, resulting in lower energy costs in long-term use.
2. Voltage regulation under load: can regulate the voltage under load without power off, ensuring stable power supply.
3. Reliability and durability: Oil-immersed self-cooling design (ONAN), no additional auxiliary equipment, low failure rate and long insulation life.
4. Easy maintenance: The sealed structure slows down the oil aging, and the lifting structure makes installation and maintenance easy.
5. Wide application scenarios: 80kV high-voltage side + multiple output levels, suitable for industrial, power grid, commercial large-scale experimental stations and other scenarios with large load fluctuations.
