Electrical Insulation Paper
Electrical insulation paper applies to rated voltage not more than 500kv transformers, reactors and other inter-turn insulation paper.
Electrical insulation paper is roll paper, roll width of 625mm-1000mm, roll diamter 550-650mm, or according to the provision of the contract order.
Aprrarent Density: 1.0-1.25g/cm3
Material: Unbleached sulphate pulp thickness: 0.1-0.5mm
Color: Brown, red, dark blue
Feature: Good mechanical stength, high electric strength resistance, larger tightness, smaller shrinkage, excellent flatness are the main strong strengths of this product.
It be mainly used in the clapboards of transformers and other components such as insulation tube.
