Electrical insulation crepe paper is a high-performance insulation material based on high-purity cellulose, specially designed for transformers, motors and other high-voltage equipment.
It has excellent flexibility, heat resistance and oil absorption to provide reliable insulation protection in extreme environments. Whether it's high voltage winding filling or a moisture barrier, this product can help extend equipment life and increase operating efficiency. At the same time, it can be used as the base material of crepe paper tubes.
