Diamond Dotted Paper is rich in stock!


This product is made of insulation paper coated by modified epoxy resin in the shape of rhombus.  It is widely used for interlayer and turn insulation of oil-immersed transformer and reactors. In the process of coil drying, the agglutinating and solidifying of DDP can bond the coil into a fixed unit. The bonding strength of epoxy resin is sufficient to prevent the displacement of the various layers of the winding in short circuit condition and further ensure the long-term mechanical and electrical properties of insulation structure.
