S13 series oil-immersed transformer
Product description
Transformers can convert the grid voltage into the voltage required by the system or load to realize the transmission and distribution of electric energy. This transformer can replace the silicon steel core transformer and is widely used in outdoor power distribution systems. The large-scale operation of this product into the network can achieve good energy-saving effects and reduce atmospheric pollution. This product is particularly suitable for areas with insufficient power and large load fluctuations, as well as areas where routine maintenance is difficult. Since the transformer adopts a fully sealed structure, the insulating oil and insulating medium are not polluted by the atmosphere, so it can operate in humid environments and is an ideal power distribution equipment in the vast power distribution network in cities and rural areas.
Features
An energy-saving product, the no-load loss is about 75% lower than that of the S9 transformer; it has low loss, less heat, low temperature rise, and stable operation; it has an advanced and reasonable structure and strong short-circuit resistance; it has strong overload capacity, is safe and reliable, has strong corrosion resistance, and is free of charge. maintain.
