Claims
- 1. 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 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.
- 2. A color cable as claimed in claim 1, further comprising a second said electrical transmission cable having at least one conductor, said second said electrical transmission cable being spaced from said at least one transmission cable, wherein a respective said at least one color winding is wound around each of said electrical transmission cables and said electrical transmission cables are commonly covered by said transparent plastic covering.
- 3. The color cable of claim 1, wherein said transparent plastic covering is made of a material selected from the group consisting of PET, PP, PVC, and PE.
- 4. The color cable of claim 1, further comprising a central positioning wire with said conductor wound around.
- 5. The color cable of claim 1, wherein said color winding is formed of a plurality of windings with different colors stranded as one.
- 6. 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.
- 7. The method of claim 6, further comprising a heating device for heating said color winding wound around said transmission cable, thereby securing said color winding on said transmission cable.
- 8. The method of claim 6, wherein said winding is coated with an adhesive in a preparatory process for increasing adhesion between the winding and the transmission cable.
- 9. The method of claim 4, wherein said color winding is formed of a plurality of windings with different colors stranded as one winding prior to being wound around said transmission cable.
- 10. The method of claim 6, wherein a plurality of color windings with different colors driven by respective associated winding devices are wound around said transmission cable sequentially.
- 11. The method of claim 6, wherein said color winding is formed of a plurality of threads with different colors.
- 12. The method of claim 6, wherein said transmission cable is formed of a plurality of conductors.
