Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The copper conductor control cables of the of the present utility model this band armouring wire as shown in Fig. 1 to 5, by improving the cross section of armouring wire 21, improve and connects compactness and allow degree of crook.This control cables is applicable to the system such as industrial frequency AC rated voltage 0.45/0.75kV and following automatic control, monitoring circuit, protection circuit, and the indoor, cable trough, pipeline, direct-burried etc. of be fixedly the laid in industries such as metallurgy, electric power, building require fire-retardant, fire-resistant and can bear the occasion of larger mechanical external force.Industrial frequency AC rated voltage is 0.45/0.75kV, uses AC system ceiling voltage to be no more than 1.0kV.Minimum bending radius should be not less than 12 times of the outside diameter of cable.
As Fig. 1, this kind of copper conductor control cables with armouring wire comprises oversheath 10, metal armor layers 20, inner sheath 30, packed layer 40, multiple traction component 50 and more than one conductor assembly 60.
This metal armor layers 20 is made up of steel wire 21 more than one deck, according to the thickness of steel wire 21, is preferably two layers.Described steel wire 21 comprises large end 22, small end 23, first constriction 24 and the second constriction 25.First constriction 24 of the described steel wire 21 of at least one holds the large end 22 of adjacent described steel wire 21, and the second constriction 25 of the described steel wire 21 of at least one holds the small end 23 of adjacent described steel wire 21.Steel wire 21 forms successively chimeric structure, and this embedded structure ensures the stable connection between steel wire 21, and when control cables distortion, steel wire 21 can the changing of the relative positions to a certain extent, and the size of adjustment diverse location, meets bending needs.Armouring wire 21, first constriction 24 when Fig. 4 display and control cable is bending and leave between the first gap 26, second constriction 25 and small end 23 between large end 22 and leave the second gap 27.After Fig. 3 display and control control cables is bending, the change of armouring wire 21.Distance between first gap 26 and the second gap 27 reduces, and the internal diameter of metal armor layers 20 increases, but still keeps occlusion preferably between steel wire 21.
Preferably, the external diameter of described oversheath 10 is 56.3mm, and the thickness of described metal armor layers 20 is 0.5 to 1mm.When metal armor layers 20 and oversheath 10 meet the requirement in size, metal armor layers 20 can play substantial effect.Described oversheath 10 and inner sheath 30 are made by polyethylene or polyolefin, and the thickness of this oversheath 10 is 2.5mm, and the thickness of inner sheath 30 is 1.2mm.
