| description | PURPOSE:To remarkably reduce disconnection failure of a stranded wire conductor due to penetration of rainwater by appropriately controlling the melt flow rate and the Vicat softening point of a resin composition filled up into the air gap between strands and between a stranded wire conductor and an insulation layer. CONSTITUTION:An aerial insulated wire 1 is composed of a stranded wire conductor 3 in which a plurality of strands 2 are stranded and an insulation layer 5 forming a cover surrounding the stranded wire conductor 3. And the air gap 4a formed between the strands 2 and the air gap 4b formed between the stranded wire conductor 3 and the insulation layer 5 are closely filled up with a watertight resin composition 4. The main ingredient of the watertight resin composition 4 is the copolymer of the foregoing polyolefine. The watertight resin composition is processed so that the melt flow rate is not less than 20 grams per 10 minutes, and that the Vicat softening point is not less than 50 deg.C. |
