2018 Hot sale 0.18mm Insulation paper for Winding insulation

DDP is made of insulated cable paper coated with rhombic thermosetting adhesive layer. It is baked and wound. When used, the coating layer starts to melt at a certain temperature during the drying process of the coil to produce adhesion. The curing begins again as the temperature rises, In the process of coil drying, the agglutinating and solidifying of DDP can bond the coil into a fixed unit.

It can be easily used and reduce the temperature rise of the transformer oil. The adhesive strength of the epoxy resin can prevent the winding and the layers from being displaced when the coil is short-circuited, thus ensuring the long-term mechanical and electrical properties of the insulation structure, widely used for interlayer and turn insulation of oil-immersed transformer and reactors.
