Diamond Dotted Insulation Paper Used As Insulation Material for Coils

Diamond Dotted Insulation Paper is made of electrical insulation paper with diamond-shape epoxy resin dotted in both sides. The epoxy resin used in D.D.P. contains a kind of incubative hardener material, it is a dry and crisp material at normal temperatures (below 35 degree C)”

This product has good dielectric and good mechanical properties after being heat solidification. It can be used as insulation material for coils and between layers of oil immersed power and distribution transformers. It has good oil absorption and does not pollute various oils. At the same time, it has excellent electromechanical properties in oil, and its coated epoxy resin can be A strong adhesive force is generated between the coil or other electrical components to prevent the displacement and looseness of the coil and the electrical components during operation, thereby ensuring the safety and reliability of the electrical equipment such as the transformer during operation.

The diamond dotted paper is coated with special modified epoxy resin in a rhombic shape on high performance insulating paper. It can be used as the turns insulation and interlayer insulation of coil wires of oil-immersed power transformers. Wire-baked baking is sufficient to prevent displacement of the layers of the line resistance, thereby ensuring stable electrical and mechanical properties of the product insulation structure.
