1. Raw material
Insulation crease paper is one of the most important solid insulation of the transformer's oil-paper insulation system, it influence to the quality and life-span
of transformer directly. The research results of these years certify that the kind
and quality of raw material is a key factor of the product quality. So the material
we required is 100% unbleached sulphate conifer wood pulp and its DP value
should be greater than 1000. 2. Application
The product applies to insulation crease paper, which is used to oil immersion transformer.3. Specification
Crease insulation paper is continuous paper. Its width is 500��5mm or 625��5mm.
