Description

High strength trailing elevator cable

Technical field

The utility model relates to a kind of elevator cable, particularly relates to a kind of high strength trailing elevator cable.

Background technology

Elevator is as the vertical transportation instrument of modern high-rise building, be closely related with the life of people, what require lift running safety, high efficiency, comfortableness etc. along with people improves constantly, elevator is rapidly developed, its drive technology has developed into frequency modulation and voltage modulation speed governing, and its logic control also replaces original Control by PLC.Be close to because escalator is one the small space closed, therefore, the selection of elevator trailing cable should follow following principle.1. meet tensile strength: have in elevator cable half be used to extend, high rise elevator can reach more than 100 meter, and the deadweight of 100 meters of cables is exactly nearly hundred kilograms, so cable must have enough tensile strength.Now commercially have the flat composite elevator trailing cable of self-bearing type, together with video coaxial cable, power line, data wire are compound to steel strand wire etc. by this cable, make a flat flat cable, the pulling force of such whole piece cable is born by steel strand wire, tensile strength is very good, can not elevator run in, because gravity breaks signal cable.2. good electric parameter: elevator trailing cable is in the process moved up and down along with elevator, and centre has one section of gravitate and occurs bending and deformation, and causes the electric parameters such as the impedance of cable and distributed capacitance to change.The cable of poor quality is when stress deformation, Parameters variation is large, impedance mismatch will be caused, video attenuation increases and produce signal reflex, this will cause vision signal signal to noise ratio to decline, generation video disturbs, so that shielded, that wire diameter is thick vision cable should be selected, to stop intrusion of interfering signal as far as possible.

Summary of the invention

The utility model provides a kind of high strength trailing elevator cable, this high strength trailing elevator cable is under the prerequisite of other original performance ensureing trailing elevator cable, improve the function of the conductor bends performance in trailing elevator cable, improve the intensity of cable conductor, prevent the generation resolving core phenomenon, thus improve the reliability of elevator cable.

For achieving the above object, the technical solution adopted in the utility model is: a kind of high strength trailing elevator cable, comprise at least 2 group conductive units, data wire and flat sheath, the described conductive unit of 2 groups of parallel interval arrangement is positioned at flat sheath and at same plane, often organize described conductive unit to be made up of 4 conductor wire cores arranged in parallel, on flat sheath between conductive unit and data wire, lower surface all has wedge groove, described conductor wire core forms by some copper conductors are stranded, this conductor wire core outer surface is coated with insulating barrier, in described flat sheath and be positioned at 2 groups of conductive units separately above and below all there are at least 2 bar shaped spaces, described conductor wire core comprises the aramid fiber rope that is positioned at center and stranded in some copper wires of this aramid fiber rope outer surface.

In technique scheme, further improvement opportunity scheme is as follows:

1, in such scheme, the diameter of described copper conductor is 0.1mm ~ 0.3mm.

2, in such scheme, be positioned at conductive unit described in 2 groups separately top, below bar shaped space number be 2.

Because technique scheme is used, the utility model compared with prior art has following advantages:

Butterfly telephone wire is laid in the utility model indoor, which overcome elevator cable bending property in prior art poor, cause conductor that the defect of disconnected core easily occurs, under the prerequisite of other original performance ensureing trailing elevator cable, improve the function of the conductor bends performance in trailing elevator cable; And conductor wire core comprises the aramid fiber rope that is positioned at center and strandedly improves the intensity of cable conductor in some copper wires of this aramid fiber rope outer surface, prevents the generation resolving core phenomenon, thus improves the reliability of elevator cable; Secondly, in its insulating jacket layer and be positioned at the first copper conductor, the second copper conductor separately above and below all there is bar shaped space, easily can reduce the dielectric constant of insulating barrier, and then reach and reduce electric capacity thus improve the transmission performance of cable, prevent cable cross-talk simultaneously, turn improve pliability, prevent frequent bending from causing external sheath layer to ftracture.
