Product Description
Diamond Dotted Paper (DDP)
Description:
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.
