High-strength strong-weak-electricity compound cable

Abstract

The invention discloses a high-strength strong-weak-electricity compound cable which comprises four power cable cores, wherein the four power cable cores are peripherally and evenly arranged, a buffercore is arranged among the four power cable cores, a central hole is formed in the middle of the buffer core, a control cable core is arranged in the central hole, four lateral holes are peripherallyand evenly formed in the outer side of the central hole and on the buffer core, reinforcing cores are arranged in the lateral holes, a water-blocking taped covering layer is arranged on the outer sides of the four power cable cores, space of the inner side of the water-blocking taped covering layer is filled with an insulation foam layer, and a halogen-free low-smoke flame-retardant polyethyleneinner protective jacket layer, a metal protection layer and a low-smoke halogen-free flame-retardant polyolefin outer protective jacket layer are sequentially arranged on the outer side of the water-blocking taped covering layer. The high-strength strong-weak-electricity compound cable disclosed by the invention has the advantages of compact structure, high compression resistance and tensile strength, ability in effectively blocking water, good rat and ant resistance, safe and reliable signal transmission and ability in achieving integrated control.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength strong and weak current composite cable. Background technique [0002] Electric power engineering, remote control, and construction engineering, no matter in the construction process or after they are put into use, the power supply system is particularly important. The cable core is the carrier of the power supply system. The strong current system and the weak current system are controlled by the power cable core and the control cable core respectively. The traditional strong current and weak current control methods are: the strong current system and the weak current system are controlled by independent power cable cores and control cable cores respectively. The traditional production process has the following problems: large processing volume and high production cost; it is not conducive to laying, Management, high risk factor; not conducive to the assembly of fin...

AI Technical Summary

Problems solved by technology

The traditional strong current and weak current control methods are: the strong current system and the weak current system are controlled by independent power cable cores and control cable cores respectively. The traditional production process has the following problems: large processing volume and high production cost; it is not conducive to laying, Management, high risk factor; not conducive to the assembly of finished products, long production cycle; large volume, waste of materials, electricity, space, cable core bridge, pipeline and labor for production and laying; complex manufacturing process, and a wide variety of raw materials required, high production cost

At the same time, the strength of the traditional cable core is small, and it is easy to break when it bears a large load or external force, which affects the normal use of the cable core; and the tensile performance of some existing cable cores is weak, and may even short-circuit when it rains , affecting the stability of signal transmission
