Excellent Insulation Properties of DDP
The rhombic dispensing paper is made of power cable paper as the substrate, with composite epoxy resin as the adhesive. It is printed on the substrate by special equipment into double-sided rhombic rubber dots, and the double-sided diamond is obtained by baking and drying. Glue insulation paper. This product has good insulation properties and processability.
The rhombic dispensing paper is an insulating material which is coated with special modified epoxy resin on the electrical insulating paper. Rhombic dispensing paper is widely used in interlayer insulation and tantalum insulation of oil-immersed power transformers. When using rhombic dispensing paper, the coating layer begins to melt at a certain temperature during the drying of the coil, resulting in adhesion. Curing begins again as the temperature rises, allowing adjacent layers of the rhombic paper winding to be reliably bonded into a fixed unit.
The adhesive strength of the rhombic adhesive paper epoxy resin is sufficient to prevent the displacement of the layers of the winding during the short circuit, thereby ensuring the long-term mechanical and electrical properties of the insulation structure. Since the resin coating of the rhombic dispensing paper is punctiform, the immersion of the oil and the discharge of gas in the insulating material are ensured, and corona and partial discharge are effectively avoided, thereby ensuring the safety and reliability of the insulating structure.
