CREPE PIPE - TRANSFORMER INSULATION MATERIAL Composition : It is produced from kraft paper. Features : Kraft papers subjected to the crepe process give flexibility to the pipes. In this way, it eliminates the risk of cracking and increases the stretching coefficient. Application : Crepe Pipes are generally used as insulators at transformer outputs. Dimensions Inner Diameter: from 3mm to 40mm Wall Thickness: From 0.8mm to 3mm Length : 1000mm
