Problems solved by technology

[0004] First: due to material reasons, the manufactured cables do not meet the requirements stipulated in HJ2501-2210 "Environmental Protection Standards of the People's Republic of China"
[0005] Second: Due to the material, the long-term allowable operating temperature of this type of cable is 65-70°C. When the boarding bridge runs for a long time or is used in high-temperature areas, especially in areas with large temperature difference between day and night and low (high) temperature throughout the year , general polyvinyl chloride cables cannot withstand low (high) temperature, resulting in cracks on the surface of the cable, affecting the normal use of the boarding bridge
Overheating often occurs, causing cables to fail, or even short circuits, damaging machinery
[0006] Third: due to material problems, the wire is easily damaged by trampling and rolling, and the insulation and protective layer are easily damaged. In severe cases, the cable core will be cut
Since the cable is used to move back and forth, pulling will make the cable longer, thinning the insulation protection layer and reducing the insulation performance
Stretching for a long time can easily cause fatigue and cracking of the cable sheath and damage the cable
[0007] Fourth: due to structural problems, the cables of the above two standards lack monitoring wire cores, and it is impossible to monitor whether the cable cores are working normally

Abstract

A cable for a boarding bridge comprises a wire and is characterized in that the wire comprises a conductor and an insulation layer, wherein the insulation layer wraps the conductor, an outer sheath layer is arranged at the outermost layer of the cable, a wrapping layer is arranged between the insulation layer and the outer sheathe layer, the thickness of the insulation layer is 0.6 to 1.6 millimeters, the diameter of the wrapping layer is D1, the D1 is more than or equal to 2.4 millimeters but less than or equal to 48 millimeters, the thickness of the outer sheath layer is T1, and the T1 is equal to (D1*0.0351+1.0) millimeters. The invention provides the cable special for the boarding bridge, and the cable is suitably used for a high-cold and high-temperature environment and is resistant to friction.

Description

technical field [0001] The invention relates to a cable, in particular to a boarding bridge cable. Background technique [0002] In today's rapidly changing economy, the tourism industry and the aviation industry are developing rapidly. Through the transformation, most of the airport terminals now use boarding bridges to get on and off the plane. When boarding, usually the number of boarding gates represents the corresponding flight. Unfamiliar with the burden of passenger aircraft, improve operational efficiency, convenient and fast, become the way of existence of modern boarding bridges. As a result, the relevant supporting facilities are constantly being updated. However, such special cables have not yet formed national standards and industry standards. In this case, ordinary cables for boarding bridges use ordinary GB / T5023 "polyvinyl chloride insulated cables with rated voltages of 450 / 750V and below" and GB / T5013 "rubber insulated cables with rated voltages of 450 / 7...
