Energy-saving, Green and Environmentally Friendly Diamond Dotted Paper
Diamond dotted paper applications have greatly shortened the production cycle of transformers, saving a lot of energy and organic solvents, thereby reducing costs and reducing environmental hazards. In addition, since the coil does not need to be immersed in paint, the transformer oil can penetrate into the inside of the coil through the uncoated portion to form an oil-paper composite insulation system with high insulation strength, and the cooling effect is good, the temperature rise is low, and the transformer is improved with reliability of operation.
The special modified epoxy resin is an insulating material on the electrical insulating paper in a rhombic shape. The products are widely used in the 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 begins to solidify as the temperature rises. The adjacent layers of the winding are reliably bonded into a fixed unit. The adhesive strength of the epoxy resin is sufficient to prevent displacement of the layers of the winding during short circuit, thereby ensuring long electrical and mechanical properties of the insulation structure.
