  Double sided Diamond Pattern Paper

1. Description: 

Double sided Diamond Pattern Paper is made of Kraft coated with heat curable epoxy resin,It is a kind of inertia material , dry and no conglutination at normal temperature (below 30'C). The diamond dotted paper will make the electric conductor felt up as a hard unit under the high temperature by its internal latency substance. When the temperature rises up to 90'C , the diamond dotted paper begins one-off thaw and then one-off soldification. When to keep the temperature at 90'C for 90 minutes, the epoxy resin would paste on neighboring cable and paper firmly. The felt intensity is as high as to 70psl at 100'C (The value at least equals to 0.275Mpa as per american standard). 

2.Specifications:

1).Density :0.85~1.10 g/cm3

2). Width: 800mm, 960mm, 1000mm, 1050mm, 1200mm, 1300mm
3).Thickness:0.08mm, 0.13mm, 0.18mm, 0.25mm

4). good dielectric properties and good mechanical properties after heat solidification

3. color: nature,brown

 

4. application :It is to be used in oil-immersed transformers for the insulation between 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.
