Description
Technical field
The present invention relates to elevator cable field, be specifically related to a kind of flat insulated aerial cable.
Background technology
At present, along with the development of society, the demand of cable rises steadily, and people are more and more higher to the requirement of cable,
Especially in the environment of aerial cable, when cable is by external stress effect, its internal wire is susceptible to displacement, causes
Cable local temperature is too high, affects the communication efficiency of cable；It is easy to occur disconnected core, outer jacket problems of crack, and once
Disconnected core, will occur fault of stop, need whole replacing, repair fairly cumbersome.
Summary of the invention
The technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of simple in construction, be difficult to
Disconnected core, it is difficult to that displacement, performance be good and the flat insulated aerial cable of high life.
The invention discloses a kind of flat insulated aerial cable, including flat oversheath, in oversheath, be provided with three pros
Shape insulation cable；Oversheath two ends are provided with one group of circular hole, are provided with tensile elements in each circular hole；If oversheath outer rim is provided with
Dry semi-circular recesses, semi-circular recesses is located at the middle position between every 2 groups of adjacent cable cores；Described insulation cable by
Heart reinforcing element, the six roots of sensation insulated wire cores being centered around outside reinforcing element and square screen layer are constituted；Wherein it is positioned at centre
Any opposite side of square screen layer of square insulation cable is provided with trapezoidal tongue, the pros of the square insulation cable on both sides
Any one limit of shape screen layer is provided with trapezoidal groove；Three square insulation cables are mutual with trapezoidal groove by trapezoidal tongue
Sealed link together.
In the present invention, it is preferable that described insulated wire cores is by aluminium alloy conductor and the poly-second that is extruded in outside aluminium alloy conductor
Alkene insulating barrier is constituted.
In the present invention, it is preferable that described reinforcing element is by centrally disposed steel core and the aramid yarn being extruded in outside steel core
Constitute.
In the present invention, it is preferable that described tensile elements is the aluminum rope of 36 thin aluminium wire twisteds, its nominal diameter is 2-
6mm。
In the present invention, it is preferable that described outer jacket is made up of sheath level PVC butyronitrile elastomer.
In the present invention, it is preferable that described semi-circular recesses is upper and lower symmetrical structure.
The beneficial effects of the present invention is:
Present invention employs steel core and aramid yarn is reinforcing element, steel core and aramid yarn strength high toughness light weight good, soft, can hold
The stress produced when being frequently bended by cable, effectively prevent cable core break；Use flexible steel cable as tensile elements, its tension
Power can bear more than 50 times of cable deadweight, makes cable have superpower resistance to tension；Outer jacket outer rim arranges semi-circular recesses,
The horizontal mechanical stress that when can effectively alleviate cable U-bend, outer jacket is subject to, enhances the resist bending of protective coverings of cable and resistance to
Mill performance.It addition, in order to preferably protect insulation cable, three cable lock are combined, not only prevent insulated wire cores and send out
Raw displacement, also prevents insulation cable to be squeezed, is difficult in the air rock at height；Two circular holes are set equally, protect tension unit
Part, prevents tensile elements to be subjected to displacement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With detailed description of the invention the present invention done below in conjunction with the accompanying drawings and further illustrate.
As it is shown in figure 1, a kind of flat insulated aerial cable of the present invention, including flat oversheath 1, set in oversheath
There are three square insulation cables；Oversheath two ends are provided with one group of circular hole 3, are provided with tensile elements 6 in each circular hole；Oversheath
Outer rim is provided with several semi-circular recesses 9, and semi-circular recesses is located at the middle position between every 2 groups of adjacent cable cores；Described
The six roots of sensation insulated wire cores that by center reinforcing element, is centered around outside reinforcing element of insulation cable and square screen layer 2 constitute；
Any opposite side of square screen layer 2 of the square insulation cable being wherein positioned at centre is provided with trapezoidal tongue 11, and both sides are just
Any one limit of the square screen layer of square insulating cable is provided with trapezoidal groove 10；Three square insulation cables are by ladder
Shape tongue 11 is mutually locked with trapezoidal groove 10 and links together.
Described insulated wire cores is 6, by aluminium alloy conductor 4 and the polyethylene layer that is extruded in outside aluminium alloy conductor
5 are constituted.
Described reinforcing element is made up of centrally disposed steel core 7 and the aramid yarn 8 being extruded in outside steel core.
Described tensile elements 6 is the steel wire rope of 36 finer wire twisteds, and its nominal diameter is 2-6mm, and steel wire rope draws
Conduct oneself with dignity up to cable more than 70 times of disconnected power, and flexibility is very well, makes cable have superpower resistance to tension.
Described semi-circular recesses 9 is located at the centre position of every 2 groups of adjacent cable cores, when can effectively alleviate cable U-bend outside
The horizontal mechanical stress that sheath is subject to, enhances resist bending and the anti-wear performance of protective coverings of cable.
Described oversheath is made up of sheath level PVC butyronitrile elastomer, this mechanical strength is high, flexibility is good and wear-resisting,
Oil resistance is excellent, and cable service life can be greatly improved.
