Embodiment 1

[0024] In order to improve the structural stability of the aluminum alloy wire cores 3 , the aluminum alloy wire cores 3 are evenly distributed outside the bent tube 2 . In this embodiment, the aluminum alloy wire core 3 includes an aluminum alloy inner core 10 , a copper cladding layer 11 , and a halogen-free flame-retardant polyolefin layer 12 arranged sequentially from the inside to the outside. Because of the skin effect of the conductor, the current mainly passes through the surface, so the copper alloy of the same specification has a resistance value close to that of copper. Under the same resistance, its AC resistance and current carrying capacity are better than copper, so the line loss is also lower than copper; The copper-clad aluminum alloy wire core 3 of the present invention has the same solderability as copper and the same contact resistance as copper; compared with the existing copper wire core material, the present invention has light weight (about 40% of copper...

Embodiment 2

[0026] On the basis of Example 12, the outer protective layer 6 is a halogen-free flame-retardant polyolefin protective layer. The material of the filler 7 is ceramic polyolefin. The material of the bending tube 2 is bending resistant plastic. Since the present invention is not easy to produce toxic smoke when encountering fire, the safety of the overall structure is better, and the ceramic polyolefin with flame-retardant and heat insulation is used to fill the gaps between the multi-strand cables, so that the overall structure will be produced when encountering fire. The armor body and the adjacent multi-strand cables do not affect each other, making it safer. Because the overall structure has better flame retardancy, the corresponding fire performance is stronger.

Abstract

The invention discloses an anti-electromagnetic interference optical fiber composite cable, which relates to the field of cables, including an optical fiber, a bent tube arranged outside the optical fiber, a plurality of parallel aluminum alloy wire cores arranged outside the bent tube, and also includes an optical fiber arranged outside the bent tube. Heat-resistant plastic insulation layer, metal strip layer, and outer sheath outside the aluminum alloy wire core; the aluminum alloy wire core and the heat-resistant plastic insulation layer are provided with fillers; the bent tube includes a plurality of connected concave Grooves or protrusions, the front section of the bent pipe is a closed ring wave type. In the present invention, the optical fiber is placed in the center of the aluminum alloy core. Compared with the traditional composite cable, the positions of the optical fiber and the aluminum alloy core are set arbitrarily, and the electromagnetic interference to the optical fiber from the outside is reduced through the aluminum alloy core.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-electromagnetic interference communication power cable. Background technique [0002] As the future power grid, the smart grid is an emerging industry that is safe, reliable, cost-effective, and green. 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. However, the structure of the optical fiber composite cable in the prior art only takes into account the traditional bending resistance, compression performance and tensile performance of the cable, but does not take into account the anti-electromagnetic interference. Contents of the invention [0003] The object of the present invention is to provide an anti-electromagnetic interf...
