Insulation Diamond Dotted Paper for Transformer

Insulation Diamond Dotted Paper for Transformer

Item Description

Description
Diamond dotted insulation paper is manufactured of electrical insulating paper coated with warmth curable epoxy resin, the epoxy adhesive is used to equally sides of the paper in a diamond pattern consisting of nine.5mm x 9.5mm diamonds with 15.9mm center spacing It is a type of materials with inertia, dry and no conglutination at normal temperature (below 30 degree C). The Diamond Dotted Paper will make the electric powered conductor eternally felt up as a challenging device below the substantial temperature by its inner latency substance. when the temperature is rising up to 90 diploma C. The Diamond Paper begins a single-off thaw and then one particular-off solidification .When to hold the temperature at ninety degree C for ninety minutes, the epoxy resin would paste on neighboring cable and paper securely. The felt intensity is as higher as to 70psi at one hundred diploma C (The price at the very least is equal to .275Mpa, The us regular)

 
Features
? Insulation class A (105 °C) according to according to IEC 641
?Kraft paper, a hundred% sulphate pulp
? High purity and mechanical energy
?Coloration normal
?Baked enamel coating: Epoxy resin , rhombic, a single or the two sides
?Good compatibility with liquid dielectic following the baked enamel coating has hardened.
?Treatment must be taken that the that the levels to be baked continue to be intently pressed from every other throughout baking time
 
Programs
It is to be utilized in oil-immersed transformers for the insulation among of coils .On the insulation layer, there is a layer dotted epoxy resin that will be transformed with substantial temperature adjust that is to be called as felt
