Abstract

PURPOSE:To improve thermal resistance, flame retardancy, and hydrolysis resistance and to ease leading work by providing an extrusion coating layer composed of a specific compound and providing a tape layer serving both as a water-barrier layer and a thermal resistance fireproof layer on the extrusion coating layer. CONSTITUTION:An insulation layer 3 extrusively coated on a conductor 1 is a thermal resistance polyester resin or its elastomer having nothing of a halogen system flame retardant, and a typical polyester resin of the layer 3 is polybutylene terephthalate, polycarbonate, or polyethylene terephtalate etc. Next, a layer 4 combining water-barrier, and thermal resistant, fireproof, and flame retardative properties is provided on the layer 3. This makes excellent thermal resistance and electrical insulation to be obtained, and leading work to be improved.
