Electrical Grade Insulating Kraft Paper

Electrical Grade Insulating Kraft Paper

One of the most commonly used insulations in the electrical and power industry is electrical grade insulating kraft paper. It is important in the process of making sure that electrical safety, thermal stability and long term stability of transformers and other electrical equipment. ACC Insulations is a reputable manufacturer of quality electrical grade insulating kraft paper that serves high industrial and transformer insulation needs.

What Is Electrical Grade Insulating Kraft Paper?

Electrical grade insulating kraft paper is an insulation material based on cellulose and produced out of high-purity wood pulp. The paper is subjected to controlled conditions to enable it to have uniform thickness, superior dielectric strength, and high absorption of oil.

The material is specially designed to be used in oil-filled transformers and electrical equipment where there is a need to be able to operate continuously at a high level of insulation performance.
