19+ years experience in power transmission & distribution equipment manufacturing, one-stop solution provider for electrical equipment.
Product details
The S11-M series 20kV transformers are new products developed for the 20kV distribution network20kV distribution transformers can effectively improve the economic power supply capacity, increase the economic transmission distance, save land resource occupation effectively reduce the line loss rate energy saving effect is obvious, is the national key promotion of energy-saving products.
The products are suitable for areas with high load density and rapid growth in power demand, as well as emerging regions or places where the current power grid foundation is weak. it can also be applied to petrochemical and other industries with high safety requirements, public places, combined substations, etc.
