We're ISO9001, CE, and GS certified and strictly adhere to their good quality specifications for European-style substation, substation transmission line, Transformer Compact Box. Our foreign trade principle is based on common development with customers. Professional quality, customer satisfaction is our quality policy. Our company is striding forward to the international modernization with our advanced management, modern equipment and high-speed development.

The 200kva fully-sealed oil-immersed transformer developed and produced by our company has the advantages of low loss and low noise, which is desirable for good energy-saving effects and reducing pollution. Compared with ordinary oil-immersed transformers, fully sealed transformers have eliminated the oil conservator. The oil volume of the transformer is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging. Enhance operational reliability and maintenance-free normal operation.
