10～35kV oil-immersed transformer
S13-M series three-phase oil-immersed fully-sealed distribution transformers are different from ordinary oil-immersed transformers. It eliminates the oil conservator. The corrugated plate heat sink of the oil tank is used for heat dissipation and cooling, and its elastic expansion and contraction compensation Increase or decrease in oil volume. The product is small in size and beautiful in appearance, realizing no hanging, no maintenance and low noise.
Scope of application: All series of products are suitable for 10kV, 20kV, 35kV power transmission and distribution systems, and can be used for power and lighting in residential areas, commercial streets, industrial and mining enterprises, and rural areas.
The low voltage coil of the transformer is wound with copper foil or semi-hard copper wire, which enhances the ability of the transformer to withstand short circuits
The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply
The fuel tank and tank cover adopt a fully sealed structure, which prolongs the service life and is maintenance-free
The transformer adopts vacuum oil injection, which can completely eliminate air bubbles in the coil and ensure stable insulation performance
Each transformer is tested before leaving the factory to ensure the safe and reliable operation of the transformer.
