Product Description

Description:
The product is an insulating material coated with special modified epoxy resin in rhombic shape on electrical insulating paper. The product is widely used for interlayer insulation and turn to turn insulation of Oil-immersed power transformers. When in use, the coating layer begins to melt at a certain temperature during the drying process of the coil, resulting in adhesion. With the increase of temperature, it begins to solidify, 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 in case of short circuit, so as to ensure the long-term electrical and mechanical properties of the insulation structure. Because the resin coating of the insulating paper on the rhombic gel is in the shape of dots, it ensures the immersion of oil and the elimination of gas in the insulating material, effectively avoids corona and partial discharge, so as to ensure the safety and reliability of the insulating structure.
