10kv erefficient transfor
10kvS11 oil-immersed transformer product advantages
1. Ultra-low loss, more power saving
Using high magnetic conductivity silicon steel sheet, the no-load loss is significantly lower than that of S9, and the long-term operation saves electricity costs and the return on investment is fast.
2. Low operating noise
The core structure is optimized, the magnetic circuit is more reasonable, and the noise is significantly smaller, making it suitable for quiet places such as residential areas, schools, and hospitals.
3. Fully sealed, maintenance-free
Corrugated fuel tank structure, insulating oil does not contact the air, free of hanging core, less maintenance, longer service life.
4. Strong resistance to short circuit
The coil has high mechanical strength, withstands power grid shocks and load fluctuations, and operates stably with low failure rate.
5. High reliability and wide application
With mature technology and high energy efficiency, it is currently the mainstream selection for urban and rural power grids, new residential areas, and industrial and mining enterprises.
