This product is an insulating material that uses a special modified epoxy resin in a diamond shape on electrical insulating paper. The product is widely used in interlayer insulation and turn-to-turn insulation of oil-immersed power transformers. When used, the coating layer begins to melt at a certain temperature during the drying process of the coil, causing adhesion, and curing begins as the temperature rises. The adjacent layers of the winding are reliably bonded into a fixed unit. The bonding strength of the epoxy resin is sufficient to prevent the displacement of the layers of the winding during the short circuit, thereby ensuring the electrical and mechanical properties of the insulating structure. Since the resin coating of the diamond dispensing paper is spotted, the immersion of the oil and the discharge of gas in the insulating material are ensured, and the corona and partial discharge are effectively avoided, thereby ensuring the safety and reliability of the insulating structure. It can also be used as a cable shielding isolation layer and an anti-corona material for high-voltage motors and electrical appliances.

The diamond gluing insulating paper is made of power cable paper as the substrate, with composite epoxy resin as the adhesive, and printed on the substrate by special equipment into double-sided diamond rubber dots, which are double-sided by baking and drying. Lingge glued insulation paper. This product has good insulation properties and processability. When the stencil is heated, the glue layer melts, bonding the windings together and maintaining sufficient tension. It is mainly used as a key insulation material for foil coils and non-impregnated coils of transformers and other electrical appliances. The use of the sizing paper for interlayer insulation can save the immersion process, save raw materials and energy, improve the heat dissipation effect of the electric appliance, and prolong the service life of the electric appliance.
