Embodiment Construction

[0015] Such as figure 1 A coaxial photoelectric composite low-voltage cable is shown, a group of optical fiber units 1 are used as the central layer, and the first insulating layer 2 is extruded on the outer layer of the optical fiber unit 1, and the outer layer of the first insulating layer 2 is loosely wound. The first conductor layer 3 is applied in a manner, and then the second insulating layer 4 is extruded on the outside of the first conductor layer 3, and the second conductor layer 5 is applied on the outside of the second insulating layer 4 in a sparsely wound manner, and then the second A third insulation layer 6 is extruded on the outside of the conductor layer, and then a layer of outer sheath 7 is extruded on the outside of the third insulation layer 6 .

[0016] In order to improve the performance of the cable again, the cross-sectional ratio of the first insulating layer 2, the second insulating layer 4 and the third insulating layer 6 is 1:2:4; The cross sectio...

Abstract

The invention discloses a coaxial photoelectric composite low voltage cable, comprising a pair twisted fiber unit in the center of the cable, a first insulating layer extruded over the fiber unit, a first conductor layer spaced winded outside the first insulating layer, a second insulating layer extruded over the first conductor layer, a second conductor layer spaced winded outside the second insulating layer, a third insulating layer extruded over the second conductor layer, and an oversheath extruded over the utmost layer of the cable, wherein the cross section ratio among the first insulating layer, the second insulating layer and the third insulating layer is 1:2:4, and the cross section of the second conductor layer is twice the cross section of the first conductor layer. The coaxial photoelectric composite low voltage cable is of a coaxial structure, and can substantially reduce the cable external diameter, and bear certain pulling force in a construction process.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a coaxial photoelectric composite low-voltage cable. Background technique [0002] Photoelectric composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method, which integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. Its common structure is that the copper conductor is cabled with the optical fiber unit, or the optical fiber unit is used as a filling part of other cables. [0003] The disadvantage of this technology is that the outer diameter of the cable is larger after being cabled, and the cable cannot bear the pulling force. Contents of the invention [0004] In order to solve the problems of the prior art, the present invention provides a photoelectric composite low-voltage cable with a coaxial structure...
