Abstract
The invention discloses a multi-core self-supporting flat lift cable, which comprises a plurality of insulated wire core sets arranged in parallel. A sheath layer is arranged outside wire cores; part of the insulated wire core sets respectively consist of a middle steel wire rope and wire cores distributed along the outer edge of the steel wire rope; the other part of the insulated wire core sets respectively consists of a middle packing layer and wire cores distributed along the outer edge of the packing layer. A second insulated layer is extruded outside the steel wire rope. The external diameter of the multi-core self-supporting flat lift cable disclosed by the invention is reduced through optimizing an internal structure to achieve the goal of saving raw materials. Through the optimization, bearing original parts originally and respectively located at the middle or both sides of the insulated wire core sets are transferred to the centers of the wire core sets, and thereby, the width is reduced finitely, so that the materials can be reduced, and meanwhile, all properties of the cable are not influenced.
Description
?
Technical field
The present invention relates to a kind of power cable, specifically is a kind of multicore self-bearing type elevator flat cable.
Background technology
Numerous insulated wire cores is not less than in the multicore self-bearing type elevator flat cable of 1.5mm2 at present, and insulated wire cores is through the stranded insulation group that forms of dividing into groups, and load bearing element all is centre or the both sides that are placed on elevator insulated wire cores group.Design causes the width of cable significantly to increase like this, and the sheath material that causes consuming increases, and causes the waste of material, does not meet modern requirements of green environmental protection.Existing elevator flat cable, its structure are that 6 insulated cores are formed one group, 6 groups altogether, and the aligning method of employing 2+2+2, diameter+6 gap length of diameter+2 steel wire rope of its width=6 an insulation group so.It is thus clear that the width of this model flat cable is longer, cause material consumption bigger.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multicore self-bearing type elevator flat cable of on the basis that does not change cable each item performance, effectively having practiced thrift material usage.
A kind of multicore self-bearing type elevator flat cable of the present invention; Comprise the some insulated wire cores groups that are arranged in parallel; At the core peripheral hardware restrictive coating is arranged, said SI semi-insulation core group is by the steel wire rope of centre, and forms along the core that the steel wire rope outer rim distributes; Another part insulated wire cores group is by the packed layer of centre, and forms along the core that the packed layer outer rim distributes.
Said core comprises middle conductor and is extruded in the first outer insulating barrier of conductor.Said steel wire rope extrudes second insulating barrier outward.
Beneficial effect of the present invention:
The present invention is that the optimization through internal structure reduces the outside diameter of cable, reaches the purpose that saves material.This optimization is to transfer to the core group switching centre with being positioned at insulated wire cores group load-bearing original papers middle or both sides originally, thereby the limited width that dwindled makes material can realize reducing, and each item performance of cable is unaffected simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and instance the present invention is described further.
As shown in Figure 1; A kind of multicore self-bearing type elevator flat cable comprises six groups of insulated wire cores groups that are arranged in parallel, and at the core peripheral hardware restrictive coating 4 is arranged; Said SI semi-insulation core group is by the steel wire rope 3 of centre; And form along the core that steel wire rope 3 outer rims distribute, another part insulated wire cores group is by the packed layer 5 of centre, and forms along the core that packed layer 5 outer rims distribute.Core comprises middle conductor 1 and is extruded in the first outer insulating barrier 2 of conductor.
Present embodiment be insulated wire cores stranded in groups before, squeeze second insulating barrier of a layer thickness more than or equal to 0.3mm in steel wire rope outside, make the external diameter of external diameter and single insulation of the steel wire rope after the insulation suitable.Total pull-off force of steel wire rope must not be less than 5 times of 200 meters cable deadweights.
Through after this ingenious change, width+4 gap length of width of the present invention=6 an insulation group obviously reduces through the width that compares it; Practiced thrift material,, used this technology and can practice thrift cable jacket material 8% ~ 30% through calculating; So a large amount of plastics are practiced thrift in this invention; Reduced cable cost, economical and practical, application prospect is boundless.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
