Description
Premium Diamond Dotted Paper (DDP) for Transformer Insulation
Diamond Dotted Paper (DDP) is a premium electrical insulation material widely used in the manufacturing and repair of power and distribution transformers. It consists of high-quality electrical insulation paper coated with thermosetting epoxy resin dots arranged in a diamond pattern. During the transformer winding process, the resin dots bond adjacent insulation layers together when heated, creating a strong, stable winding structure with excellent mechanical and electrical properties.
At Star Group of Companies Caribbean, we supply premium-quality Diamond Dotted Paper (DDP) in Trinidad and Tobago, manufactured to provide superior dielectric strength, thermal endurance, and oil compatibility. Our DDP improves winding stability, reduces conductor movement during short circuits, and enhances the long-term reliability of transformer insulation systems.
Designed to meet international transformer industry standards, our Diamond Dotted Paper is suitable for transformer manufacturers, repair facilities, utility companies, and industrial applications throughout Trinidad and Tobago and the wider Caribbean.
