Development of Specialty Papers is an Art: Electrical Insulation Paper from Indigenous Raw Materials — Part IX

Abstract

Electrical insulation papers have wide applications in the most different branches of engineering viz. , high tension power cable, telephone cable, wire winding, and capacitor or condenser. Paper is the cheapest source and has outstanding electrical properties and dielectric constant among known insulating materials. It needs to develop certain physical, chemical, and electrical properties. In order to develop electrical insulation paper, it is imperative to modify process water quality as well as paper manufacturing process. As the O₂ delignified pulp is refined extremely far, up to more than 90^o Schopper-Reigler,

In this study possibility of <i>Cannabis sativa </i>hemp ribbons were explored to develop various electrical insulation papers like, high tension power cable paper, telephone cable paper, and capacitor tissue paper.</span>
