S series 35kV power transformers are widely used in urban and rural distribution networks, industrial parks, large industrial and mining enterprises, railroad transportation, power plants and other places with high requirements for energy saving and environmental protection. The product is the ideal choice for optimization and upgrading of modern power distribution network by virtue of high energy efficiency, stable operation and low noise.
1. Strong adaptability: S series has high temperature resistance and overload capacity, capable of long-term stable operation in high temperature, high load rate and other harsh environments.
2. Exquisite appearance: the appearance of the product by a comprehensive grinding and rust treatment, the use of powder spraying process, equipped with a wide slice radiator, to ensure that the coating is as new as long-lasting, do not fade.
3. Non-leakage design: the seals are made of acrylate material, and the one-time molding technology ensures that the product will never leak. The equipment passes positive and negative pressure leakage test before leaving the factory, reliable quality.
4. Safe and environmentally friendly design: the materials and processes are in full compliance with safety and environmental protection requirements, no release of toxic gases, low smoke concentration during combustion, non-corrosive, to ensure that the equipment is environmentally friendly.
Low loss design
S series adopts new iron core and optimized winding structure design, which reduces no-load loss by more than 20% and load loss by more than 10% than traditional transformers, and significantly improves energy efficiency.
Low noise operation
Adopting high-quality silicon steel sheet and optimized magnetic circuit design, the noise level is significantly reduced to meet the environmental requirements of modern cities and residential areas.
High Reliability
The winding and body are tightly designed to have strong short circuit resistance. The use of high-quality insulating materials and high-temperature-resistant transformer oil ensures safe operation and prolonged service life.
Environmental protection and energy saving
The insulating oil adopts non-polluting and recyclable environmentally friendly insulating oil. The product material can be recycled, with excellent sealing performance, no leakage and maintenance-free.
