Products introduction:
10KV oil immersed transformer
The product complies with the national standard GB1094-1996 and GB /t6451-2008. This is the latest series product with low loss copper winding. It is made of high-quality materials. New technology and materials are used for coil body and insulation. This product shows advantages of low loss, low noise and high efficiency, and can achieve good energy-saving effect and reduce pollution.
12KV oil immersed transformer
The 12kV fully-sealed oil immersed power transformer shows advantages of low loss, low noise and high efficiency, which achieve good energy-saving effect and reduce pollution. Compared with the normal oil immersed transformer, the fully-sealed transformer cancels the external oil tank. The change of oil volume 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 oil deterioration and aging of the insulation. This enhance the operation reliability, and free maintenance under normal operation.
