Abstract
The utility model relates to a comprehensive cable dedicated to a passenger elevator. The comprehensive cable comprises power lines, a video line, and an outer sheath layer. The video line is disposed at the center of the outer sheath layer. The power lines are arranged around the video line circumferentially. The video line comprises a group of video line conductors and a first insulating layer wrapped around the group of video line conductors. The first insulating layer is wrapped in a weaving layer. The weaving layer is wrapped in a sheath layer. Each power line comprises a group of power line conductor and a second insulating layer wrapped around the group of power line conductor. The comprehensive cable dedicated to a passenger elevator has characteristics of strong resistance to tension, steady video signal transmission, high definition, and a long service life.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of passenger lift private cable.
Background technology
Along with the development of technology and the raising of people's living standard, passenger lift has been not only the passenger carrying tool of upper and lower floor, but the organic component of whole building environment, in the sedan-chair of passenger lift, aspect environment and comfort level, there is more and more higher requirement, the elevator cable of available technology adopting, because signal attenuation amplitude is large, the ability of anti-electromagnetic interference is little, cause the video signal transmission definition in elevator to reduce, and in the process of moving up and down along with elevator, easily there is the phenomenon of jitter in signal.Because elevator has strict demand to the weight of carrying, therefore, improving under the prerequisite of elevator cable signal stabilization, also to guarantee that elevator cable has the good poor and good tensile strength of anti-mechanical impulse force.
Summary of the invention
The utility model is in order to address the above problem, and provides that a kind of resistance to tension is strong, video signal transmission stable, the passenger lift private cable of the high and long service life of definition.
The technical solution of the utility model is:
A kind of passenger lift special comprehensive cable, comprise power line, video line and external sheath layer, described video line is located at the center of external sheath layer, power line is the circle-shaped periphery that is arranged in video line, described video line includes one group of video line conductor and is enclosed in the first insulating barrier outside described one group of video line conductor, the first insulating barrier is provided with braid outward, and braid is provided with restrictive coating outward; Described power line contains one group of power line conductor and is enclosed in the second insulating barrier outside described one group of power line conductor.
Described video line conductor is single core copper conductor, and the first insulating barrier is foaming fluoroplastics, and braid is annealed copper silk, and the material of restrictive coating is polyolefin.
Described power line conductor is stranded soft copper body, and the second insulating barrier is crosslinked polyethylene.
Described external sheath layer is low-smoke halogen-free polyolefin.
Useful good effect of the present utility model is:
1. the tensile strength of the utility model passenger lift special comprehensive cable is high, long service life, the conductor of its video line adopts single core copper conductor, and the first insulating barrier adopts physical blowing fluoroplastics, and braid adopts annealed copper silk, restrictive coating adopts superpower flexible polyolefin, reaching in the key property of similar video line, improving the transmission definition of signal, reducing signal attenuation, promote anti-electromagnetic interference capability, and alleviated the quality of cable itself.
The power line of the utility model passenger lift special comprehensive cable adopts the stranded soft copper conductor of the 6th class, the second insulating barrier of its periphery adopts crosslinked polyethylene plastic, external sheath layer adopts low-smoke halogen-free polyolefin, flexibility and the tensile strength of cable have not only been improved, promote the insulation property of cable simultaneously, and realized cable environmental protection and good fire resistance.
