摘要:
Provision of a protective cover for a fibrous layer of insulation on a conductor by forming an inner layer of the protection cover by depositing a polymeric based composition without creating a crushing effect, and then, in tandem, hardening the inner layer and applying a second coat by extrusion. The inner layer absorbs the crushing forces of extrusion to protect the fibrous layer during addition of the second layer. The inner layer is preferably formed by electrostatic deposition coating and prevents pinhole formation in the second layer.
