Meanwhile, in order to improve the watertight effect, the inner wrapping tape 1 is wrapped by the inner sheath 2. In order to realize effective pulling and abnormal bending protection for the inner sheath 2, an armor layer 3 is distributed outside the inner sheath 2. In order to realize proper limit on the armor layer 3, an outer wrapping tape 4 wraps the armor layer 3. In addition, in order to meet the requirement of the natural outer layer protection of the composite cable, an outer sheath 5 is wrapped outside the outer wrapping tape 4,

in view of a preferred embodiment of the present invention, in order to effectively satisfy the reasonable distribution of the power unit 6 and the light unit 7, the power unit 6 and the light unit 7 are not affected by the usage function, and are arranged as close as possible without unnecessary collision and extrusion, and the power unit 6 and the light unit 7 are twisted with each other. Specifically, the three optical units 7 are arranged mutually, a storage space is formed between the outer sides of two adjacent optical units 7 and the inner wrapping tape 1, and two power supply units 6 are distributed in the storage space. Meanwhile, a filling core 8 is arranged between the light units 7. In this way, unnecessary compressive stress toward the center position at the joint between the light units 7 may not occur, and stable attachment of the three light units 7 may be satisfied. During implementation, the filling core 8 may be formed by using a technical or non-metallic filler, which is not described in detail herein.

Further, the adopted power supply unit 6 comprises a plurality of power supply line bodies 9, the power supply line bodies 9 are wrapped with extrusion insulation layers 10, and the power supply line bodies 9 are coated with water-resistant colloid.

Therefore, the power supply unit 6 and the light unit 7 have proper water tightness, the protection effect can be prolonged to the maximum extent by water embedding even if the outer sheath 5 is damaged by accident, and the subsequent maintenance and rush repair period is convenient for not causing corrosion damage to the power supply unit 6 and the light unit 7.

In combination with practical implementation, the inner wrapping tape 1 and the outer wrapping tape 4 are formed by winding non-woven fabrics, and the winding thickness is 1-2 cm. Therefore, the constraint limiting can be realized, unnecessary distribution dislocation in the composite cable is avoided, and wrong compression deformation stress cannot be formed at a certain specific point.
