ELECTRICAL CABLE HAVING A SURFACE WITH REDUCED COEFFICIENT OF FRICTION

摘要

The present invention includes a cable (12) having reduced surface friction and the method of manufacture thereof including the steps in which a conductor wire (14) is coated with a first plastic material and with a mixture of a second plastic material (17) and lubricating material (19) and the coated conductor wire (12) is cooled. The cable (12) includes at least one conductor core (14) and a least two coatings of plastic material and incorporates a lubricating material (19) in and/or on the outer layer of plastic material (17). The equipment (11) for manufacturing of the electrical cable (12) includes a reel (13) for supplying a conductor wire (14) to an extruding head (15), which is connected to tanks (16 & 18) containing plastic material (17) and lubricating material (19) for coating the conducting wire (14), and a reel (21) for taking up the cable (12).
