Product Description
Oil immersed transformer insulation raw materials
Oil transformer use dotted pattem paper
Oil transformer use double sides coated dotted pattem paper
Oil transformer use double sides coated dotted pattem paper
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 of 9.5mm 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 other during baking time
Applications:
It is suitable for turn-to-turn insulation of coil wires on oil-immersed power transformersand suitable for layer insulation of coils on distribution transformers.
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
