Mohammad Azadfallah; Hamid Khodabandehlo; Amirabas Shaygani Akmal

Volume 31, Fall 3 , September 2016, , Pages 446-457

https://doi.org/10.22092/ijwpr.2016.106280

Abstract
  The oil-impregnated dielectric papers are the main components of distribution transformer which govern its service time. Therefore, durability enhancement of this grade of paper will cause to extend transformers life. Hence in this research long fiber unbleached Kraft pulp and mixture of it with bagasse ...  Read More

Pulp and paper
The effect of pulp and cellulose nanofiber cyanoethylation on the physical properties of transformer insulating paper

Mohammad Azadfallah; Hamid khodabandehlo; Amir abas Shayeghani akmal

Volume 31, SPRING 1 , March 2016, , Pages 1-13

https://doi.org/10.22092/ijwpr.2015.105604

Abstract
       The properties of transformer electrical insulating papers are influenced by fiber chemical modification process. In this research, the effect of cyanoethylation of fibers and addition of cyanoethylated cellulose nanofiber (CNF) on dielectric properties including capacitance, dielectric ...  Read More
