Diamond dotted paper(DDP) is produced of insulating paper with diamond-shape epoxy resin dotted on the two sides. The epoxy employed in D.D.P includes a kind of incubative hardener materials. It is a dry and crisp substance at regular temperature.
This solution has very good dielectric properties and excellent mechanical houses soon after heat solidification. It is to be utilised in oil-immersed transformers for the insulation in between of coils and among layers of oil immerged electrical power distribution transformers.
Diamond sample paper produced of Kraft paper coated with warmth curable epoxy resin.The epoxy adhesive is utilized to each sides of the paper in a diamond sample consisting of nine.5mm x9.5mm diamonds with 15.9mm centre spacing.
It is a kind of substance with inertia, dry and no conglutination at standard temperature (under 30ºC). The Diamond Dotted Paper (DDP)will make the electric powered conductor permanently felt up as a hard device under the substantial temperature by its internal latency compound. When the temperature is increasing up to 90ºC, The Diamond Sample Paper (DDP)commences one particular-off thaw and then a single-off solidification. When to preserve the temperature at 90ºC for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely and securely. The felt depth is as large as to 70psl at 100ºC.(The value at least is equal to .450Mpa) (IEC regular)
This item has great dielectric homes and very good mechanical homes after heat solidification. It is to be used in oil-immersed transformers for the insulation in between of coils and in between levels of oil immerged electrical power distribution transformers.
The Diamond Dotted Paper to be used in oil immersed transformers, for coil insulation. On the insulation layer, there is a layer dotted epoxy resin that will be transformed with substantial temperature alter that is to be known as as felt. It is appropriate for change-to-turn insulation of coil wires on oil-immersed electricity transformers and suited for layer insulation of coils on distribution transformers.

two). Width: 800mm, 960mm, 1000mm, 1050mm, 1200mm, 1300mm or CZPT.
3).Thickness:.08mm, .13mm, .18mm, .25mm, .38mm, .50mm or CZPT.
4). great dielectric properties and very good mechanical properties right after heat solidification
five). Coloration: nature, brown
It is to be employed in oil-immersed transformers for the insulation in between coils. On the insulation layer, there is a layer dotted epoxy resin that will be transformed with higher temperature alter that is to be named as felt.
In the approach of coil desiccation, the coated epoxy-resin would be melted in a certain temperature and turn out to be adhesive. With the temperature increased, the melted resin would treatment to C-phase, and firmly adhere every adjoining layer of the coil, thus forming a winding area. If a short circuit occurs in the coil, the resin bond power would sufficiently prevent the displacement of each winding layer, which guarantees the prolonged-term mechanical and actual physical properties of the insulation construction. As the resin coating distributes in a diamond-dotted sample, small amount of the resin would soak into the insulating paper throughout the melting and curing process, which guarantees the elimination of air material in the insulating paper and assures the soakage of oil, reducing the damages of corona and partial discharge.
