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.
The product is a universal interlayer insulating paper for transformers. It has good oil absorption and does not pollute various oils. It also has excellent mechanical and electrical properties in oil. The epoxy resin coated on it can produce strong adhesion with coils or other electrical components to prevent coils and electrical components from running. The displacement and looseness in operation ensure the safety and reliability of transformer and other electrical equipment in operation.
Our company has 60 years of production experience, the DDP produced by ROHS certification. It has the most advanced dispensing paper production line in China, with a monthly output of 60 tons. Paper uses the best quality base paper in the country.
