Application of Electrical Materials in Insulation
- By : Insulation Materials
The special modified epoxy resin is a rhombic insulating material on electrical insulating paper. The product is widely used in interlayer insulation and turn-to-turn insulation of oil-immersed power transformer. When used, the coating begins to melt at a certain temperature during the coil drying process, which produces adhesion effect. With the increase of temperature, it begins to solidify again, so that the adjacent layers of the winding can be reliably bonded into a fixed unit. The adhesive strength of epoxy resin is enough to prevent the displacement of each layer of winding during short circuit, thus ensuring the electrical and mechanical properties of long insulation structure.
Because the resin coating of rhombic dispensing paper is dotted, it ensures oil immersion and gas discharge in insulation material, effectively avoids corona and partial discharge, thus ensuring the safety and reliability of insulation structure. It can also be used as cable shielding isolation layer and corona-proof material for high voltage motors and electrical appliances.
