Description
Description
Diamond dotted insulation paper is made of electrical insulating paper coated with heat curable epoxy resin, the epoxy adhesive is applied to both sides of the paper in a diamond pattern consisting of9.5mm x 9.5mm diamonds with 15.9mm center spacing It is a kind of material with inertia, dry and no conglutination at normal temperature (below 30 degree C). The Diamond Dotted Paper will make the electric conductor forever felt up as a hard unit under the high temperature by its internal latency substance. when the temperature is rising up to 90 degree C. The Diamond Paper begins one-off thaw and then one-off solidification .When to keep the temperature at 90 degree C for 90 minutes, the epoxy resin would paste on neighboring cable and paper safely. The felt intensity is as high as to 70psi at 100 degree C (The value at least is equal to 0.275Mpa, America standard)
Features
- Insulation class A (105 °C) according to according to IEC 641
- Kraft paper, 100% sulphate pulp
- High purity and mechanical strength
- Color natural
- Baked enamel coating: Epoxy resin , rhombic, one or both sides
- Good compatibility with liquid dielectic after the baked enamel coating has hardened.
- Care should be taken that the that the layers to be baked remain closely pressed against each otherduring baking time
Applications
It is to be used in oil-immersed transformers for the insulation between of coils .On the insulation layer,there is a layer dotted epoxy resin that will be changed with high temperature change that is to be called as felt
Available
Thickness: 0.05mm - 0.35mm
Both in roll and sheet are available
Width: 650mm - 1350mm
