Insulation crepe paper for transformer is made of insulating kraft paper processed by crinkling.
Insulation crepe paper for transformer has high compatibility with the transformer oil, which can be used in oil-immersed transformer, mutual inductor and electric reactor.
Insulation crepe paper for tansformer is one of the most important solid insulation materials used in transformers.
Its quality directly influences the life span of the transformer.
The BDV is enhanced by up to 80% as compared to base kraft paper.
To ensure of best quality of Crepe paper, the base kraft paper is manufactured using longer fibers of pure wood pulp.
