The S13 Series 10kV oil-immersed transformers provide long service life and maintenance-free performance. The fully sealed structure connects the tank cover and tank rim via bolts or welding, isolating the insulating oil from air and preventing moisture absorption of insulation. This greatly slows down insulation aging and extends service life.
The product features a compact design and low operating noise. With new materials and advanced processes, noise is effectively reduced. The conservator-free design makes the overall height lower than similar products. No oil replacement is required during its normal service life, improving the safety and reliability of grid operation.
Transformers are core equipment in power grid construction. With emerging industrial demands, developing energy-saving, low-noise, and intelligent distribution transformers has become an inevitable trend. The S13 Series 10kV oil-immersed transformers designed and manufactured by our company adopt a fully sealed corrugated tank structure, featuring maintenance-free operation, easy servicing, stable performance, and remarkable economic benefits.
