System for manufacturing cables has magnetic shielding arranged between current-carrying coil and casing of movable tube of telescopic vulcanization tube

摘要

The system has an extrusion device with one or more extruders and a spray head through which the cable conductor or conductors pass(es), a vulcanization tube with a telescopic tube adjacent to the spray head and an induction heating system inside the movable tube (6) with a coil (7) enclosing the cable(15). Magnetic shielding (16) is arranged between the current-carrying coil and the casing of the movable tube.
