BOW-TYPE DROP PHOTOELECTRIC COMPOSITE CABLE

WIPO Patent Application WO/2022/077730

A1

A bow-type drop photoelectric composite cable, comprising a sheath unit, a first power transmission body, a second power transmission body, and a bow-type drop light unit; the sheath unit consists of first to fourth sheathes (11-14), the bow-type drop light unit consists of a light guide fiber (44), a first reinforcing member (42) located on the upper side of the light guide fiber (44), a second reinforcing member (43) located on the lower side of the light guide fiber (44), and a bow-type protective cover (41) covering the light guide fiber (44), the first reinforcing member (42), and the second reinforcing member (43); and the first power transmission body is located in the second sheath (12), the second power transmission body is located in the third sheath (13), and the bow-type drop light unit is located in an optical communication hole. Said composite cable has the main beneficial effects of having a simple structure, being easy to manufacture, consuming less materials, and having low cost and good heat dissipation effect, and two functional cables can be laid at a time, thereby having high construction efficiency.
