Therefore, colorful cable is obtained by changing color, number of strand, or winding of the winding during the process. Further, a decoration purpose is achieved. The color of cable is varied as electrical specifications and usage, whereby user can recognize the same from the color of cable. It is another object of the present invention to provide a color cable and the manufacturing method therefor wherein the color of the winding wound around the conductor body can be seen through the surrounded transparent plastic material, resulting in a colorful cable. It is still another object of the.present invention to provide a color cable and the manufacturing method therefor wherein the color of the cable can be varied as electrical specifications and usage, whereby user can recognize the same from the color of cable. Therefore, the present invention relates to 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 0.036 mm and a width of between approximately 1 and 3mm, wherein edges of said strip are overlapped to form an overlapped region of between approximately 20% and 50% the width of the step; and an extrusion molded transparent plastic covering formed on said at least one color winding.

As a result, the color of winding 3 may be seen from outside through the transparent plastic covering 4. Referring to FIG. 1 specifically, the number of conductor body 20 may be varied as the applications (e.g., two conductor bodies 20 are shown). Importantly, they are spaced from each other if two or more sets of conductor bodies 20 are provided in" order to maintain insulation therebetween. Also, the number of conductor 21 is varied as applications. For example, the number of conductor 21 is at least one. Referring to FIG. 2 specifically, where a central positioning wire 1 is provided with six conductors 21 wound around to form a conductor body 20. Also, color winding 3 may be formed of a single color, or alternatively two or more windings 3 with different colors stranded as one. As a result, a colorful cable is obtained by changing the color of winding 3, number of strand thereof, or winding of the winding 3. Also, the color of winding 3 may be seen from outside through the transparent plastic covering 4.
