Products Description
Insulating Paper for Transformer is one of the main insulating materials of oil-immersed transformers. Since power transformers have to withstand intermittent mechanical stress, tension, pressure, torsion, and the impact of atmospheric over voltage and internal over voltage during operation, it has a great impact on Insulating materials are very demanding.
Therefore, the insulation paper produced by our company strictly controls the quality to meet the application requirements of transformers.
