Noctilucence medium-voltage photoelectricity composite cable

Abstract

The invention discloses a noctilucence medium-voltage photoelectricity composite cable, and relates to the field of composite cable manufacturing. The noctilucence medium-voltage photoelectricity composite cable comprises a semi-conductive band wrapping layer, a monitoring layer, an inner protective layer, an outer sheath and three insulation power cable cores. The insulation power cable cores and an optical cable element are twisted to form a cable core. A tensile reinforcing part is arranged on the outer side between every two adjacent insulation power cable cores. The cable core is sequentially provided with the inner protective layer, the semi-conductive band wrapping layer, the monitoring layer and the outer sheath from interior to exterior. Monitoring cable core conductors are evenly arranged in the monitoring layer. The outer surface of the outer sheath is evenly coated with a layer of spiral noctilucence stripes. The noctilucence medium-voltage photoelectricity composite cable is simple in structural design, stable in performance, capable of being self-luminous or capable of reflecting light to improve the visibility at night, and capable of integrating the functions of electric energy transmission, signal control and video message transmission, and has the good tensile performance, the good wear-resisting performance, the good grinding-resisting performance and the like.

Description

technical field [0001] The invention relates to cables, in particular to a luminous medium-voltage photoelectric composite cable. Background technique [0002] Due to the large area of ​​open-pit coal mine operation (generally ranging from tens of square kilometers to hundreds of square kilometers), the main excavation equipment used in open-pit coal mines is electric shovel or dragline, and the power and signal control of the equipment and video information are mainly transmitted by cables. In general, the distance between the mobile substation of an open-pit coal mine and the electric shovel or dragline and other electrical equipment is from several kilometers to tens of kilometers. The service life of such cables is generally very short. Frequent replacement of cables not only increases the production cost of the enterprise, And seriously affected the normal production. At present, the main reasons for the short service life of this type of cable are the following two as...

Problems solved by technology

[0004] In order to meet the above requirements and solve the problems of mis-pressing cables due to poor visibility at night when loading cars, cable power and control signal transmission cables are laid separately, and the cables have poor tensile, wear-resistant and rolling-resistant performance, the invention provides a luminous medium-voltage cable. Photoelectric composite cable, which has good visibility at night, a combination of power and signal performance, and excellent tensile, wear-resistant, and rolling-resistant cables, which significantly prolongs the service life of the cable and improves the safety of the production environment
