Excellent Materials

  • Because we use oxygen-free copper lines of lower resistivity,which will become

smoother and burr-free after series of additional surface treatment,so the load loss

of our transformer is lower and the electric performance is better.

  • We use high-quality silicon-steel plates which are of lower unit loss,and the no-load

of the transformers is lower.

  • We use high quality wooden laminating insulation pieces,which won't split or move

even underr the influence of short circuit.

  • We use thoroughly filtrated transformer oil containing less water,gas and impurities,

which makes our transformers work better

  • We use high quality rubber sealing material,which can prevent the transformers from

aging or leakage.

  • All raw materials has passed the quality testing,and all the raw material factories has

pass through the national standard ISO9000 inspection.
