ABSTRACT:
A method and apparatus for forming an electrically conductive layer on a corrosion-resistant layer which covers a cable. The cable is passed through a powder accumulating tank in which are mixed an electrically conductive powder and binder powder so as to allow the mixed powder to initially adhere to the surface of the cable. The mixed powder is then pressed against the surface of the cable first at a cable outlet of the powder accumulating tank and then with a powder applying device in which an endless powder applying belt or cloth is rotated around the cable at a rotational speed dependent upon the linear speed of the cable. The surface of the cable is then heated to melt the binder powder and cause the electrically conductive powder to yet more firmly adhere to the surface of the cable. The cable is then cooled and wound.
