Kraft and Diamond Dotted Paper
Diamond Dotted Presspaper improves the mechanical strength of oil-filled transformer windings without reducing partial discharge levels. The size and shape of the dots are carefully chosen to avoid interfering with vacuum drying and oil impregnation.
During B-stage, the resin dots are dry and tack-free, permitting storage and handling similar to normal presspaper. When the winding is heated for drying purposes, the adhesive dots melt and cure, thus creating permanent bonding sites unaffected by further heating cycles that may occur in service. The bonding strength is adequate to support effective gluing in unsupported coil design.
