Halogen-free waterproof sunlight resistance industrial control equipment cable

Abstract

The invention discloses a halogen-free waterproof sunlight resistance industrial control equipment cable which has the advantages of being good in flexible performance, high in antifatigue performance and electromagnetic interference resistance and capable of meeting the demand of harsh using and mounting places. The cross section structure of the halogen-free waterproof sunlight resistance industrial control equipment cable comprises an annular protecting sleeve, a braid layer and a cabling structure which are sequentially arrayed from outside to inside. The halogen-free waterproof sunlight resistance industrial control equipment cable is characterized in that a cavity between the outer ring face of the cabling structure and the braid layer is filled with filler which is specifically formed by halogen-free cotton threads in a twisting mode, a single-core wire is further arranged in the cavity between the outer ring face of the cabling structure and the braid layer, the outer layer of the single-core wire is provided with an outer insulation layer in a wrapping mode, the cross section structure of the cabling structure comprises an annular inner protecting sleeve, an outer aluminium foil Mylar shielding layer and an inner aluminium foil Mylar shielding layer which are sequentially arrayed at one time from outside to inside, and a signal line structure is arranged in an inner cavity of the inner aluminium foil Mylar shielding layer.

Description

technical field [0001] The invention relates to the technical field of cable structures, in particular to a halogen-free waterproof and sunlight-resistant industrial control equipment cable. Background technique [0002] Communication equipment occupies a pivotal position in the entire industrial system. Its quality is directly related to the quality of industrial products, because many operating requirements are input through the control panel and transmitted to the machine through the cable. If the cable signal is not Well, the product will definitely be scrapped after it is made. Nowadays, the industrial fields are becoming more and more extensive, and the projects developed are becoming more and more high-end, such as wind energy and solar energy.

AI Technical Summary

Problems solved by technology

[0003] In tropical areas, cables often leak electricity due to long-term rainwater soaking or the cables are damaged by high-intensity sunlight, which leads to machine stop and power outage, which brings great troubles to the lives of local residents.

Especially in hydropower stations in tropical areas, when the gate is loosened or fails, the sheath of the cable will be invaded by water. The cables currently on the market cannot meet the requirements of being completely waterproof and resistant to sunlight
