Diamond Dotted insulation paper for transformer

Diamond Dotted insulation paper for transformer

Description:
It is an insulation material which Coating modified epoxy resin as diamond-shape and baking on the electrical insulation paper. Widely used in the oil-immersed transformers and mutual inductors’ layer insulation and turn insulation. When using, the coating layer begin to melt during the coil drying process at a certain temperature. resulting adhesion. As the temperature rises again curing, make the adjacent layers of the winding reliably bonded into a fixed unit. The bonding strength of the epoxy resin is sufficient to prevent the displacement of the various layers of the winding when short circuit, so as to ensure the long-term mechanical and electrical properties of the insulation structure.
Specifications:
Thickness: 80um(0.08mm),130um(0.13mm),180um(0.18mm),200um (0.20mm)    250um (0.25mm)
width:  1000 mm or cut as user’s requirements.
Roll diameter: 250~300mm  Single roll weight: about 45~60Kg.
