Hashirimizu prevention cable

摘要

(57) [summary] [purpose] of cable having a metal sheath, such as corrugated aluminum sheath, to prevent the longitudinal direction of Hashirimizu. [Configuration] The thermally expandable material is coated on the cable core 1, The anticorrosion layer 4 made of a corrugated aluminum sheath 3 and a vinyl chloride resin on the outside are sequentially extrusion coated, in heat during these extruded, thereby expanding the heat expandable material, Hashirimizu path by the thermal expansion layer 2 It fills the gap between the cable core 1 and the corrugated aluminum sheath 3.
