FIELD: electric cable manufacture.
SUBSTANCE: proposed method includes following procedures: (a) conductor feeding at predetermined feed rate; (b) extrusion of thermoplastic insulating layer in position radially external with respect to conductor; (c) cooling down of foamed insulating layer; (d) production of circumferentially closed metal shield about mentioned extruded insulating layer. Novelty is that procedures are conducted uninterruptedly, that is, time passed from end of cooling procedure to initiation of shield formation is inversely proportional to conductor feed rate.
EFFECT: reduced manufacturing time, enhanced mechanical strength of cable.
