Abstract
A color cable and the manufacturing method thereof involves an electrical transmission cable having one or more conductors, one or more color windings uniformly wound around and secured to conductor body by heating, and a transparent plastic covering formed on the winding by injection molding. The color of the winding may be seen from outside through the transparent plastic covering. A multi-colored cable is obtained by changing the color or number of the strands, or by substituting strands or windings of one color for strands or windings of another color during winding.
Claims12
A color cable comprising:
- at least one electrical transmission cable having at least one conductor;
- at least one color winding uniformly wound around and secured to said cable, said at least one color winding including a strip having a thickness of between approximately 0.015 and 0.035 mm and a width of between approximately 1 and 3 mm, wherein edges of said strip are overlapped to form an overlapped region of between approximately 20% and 50% the width of the strip;
- and
- an extrusion molded transparent plastic covering formed on said at least one color winding.
A color cable manufacturing method comprising the steps of:
- (a) uniformly winding at least one color winding around at least one electrical transmission cable by at least one winding device to form a color cable;
- and
- (b) guiding said at least one electrical transmission cable through an extrusion molding device to surround said color cable with a transparent plastic material,
- wherein each said at least one electrical transmission cable in said color cable is spaced from all other electrical transmission cables in said color cable, and
- wherein said step of winding comprises the step of forming an overlapped region of between approximately 20% and 50% the width of the strip.
