China quality Electrical Insulation semiconductor crepe paper is typically made from unbleached sulfate wood pulp paper as the base material, impregnated or coated with conductive substances such as carbon black, and then processed using a special creping process. Simply put, it is a combination of ordinary insulating crepe paper, conductive carbon black, and a special crepe structure.By precisely controlling the amount of carbon black added, its surface resistivity and volume resistivity are stabilized within a specific "semiconductor" range. This resistance value can effectively homogenize the electric field without causing short circuits or excessive losses.This is its core characteristic.It can homogenize the electric field, prevent partial discharge and insulation breakdown, and inherits the high tensile strength and toughness of cable paper, making it less prone to tearing during wrapping and installation. At the same time, it is highly compatible with the impregnating agents (or casting resins) of cable accessories, together forming a complete insulation system.
