Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is for having increased the structural representation of tensile elements original paper on the basis of Fig. 1 example.
Embodiment
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Such as Fig. 1, bucket wheel machine high-voltage flat cable of the present utility model comprises parallel and keep at a certain distance away three power cores arranging and control and optical cable core group, and outermost layer extrudes polyurethane jacket 7.Wherein:
The structure of power core is: middle for conductor 1, outside conductor 1, set gradually conductor shield 2, insulating barrier 3, insulation screen 4, semi-conductive tape lapping layer 5, soft copper silk braid 6.
Power line core conductor 1 adopts soft round copper wire, and conductor shield 2 material therefors are for conducting electricity the cross-linking type ethylene-propylene rubber.Insulating barrier 3 material therefors are the Ethylene Propylene Terpolymer rubber, and insulation screen 4 material therefors are for conducting electricity cross-linking type butyronitrile rubber.
Control and optical cable core group comprise concentric stranding together some control cores and an optical cable 10, middlely fill soft non-hygroscopic rope 11, and outermost layer is with non-hygroscopic band 12 wrapped tightening.Control core wherein is by control line core conductor 8 and be extruded in the outer control line core insulations 9 of control line core conductor 8 and form.
The production method of above-mentioned cable:
By banbury insulation rubber, interior outer shielding layer rubber being processed into respectively can three layers of elastomeric compound of once extruding;
Outside the conductor 1 of power core, pass through the three-layer co-extruded extruder of catenary suspension type continuous vulcanization with conductor shield 2, insulating barrier 3,4 extrusion moldings of insulation shielding, the production linear speed is: 3～7 m/mins, the extruder screw draw ratio is 16D, extruder temperature is controlled at 50 ℃～80 ℃, the curing tube temperature is controlled at: 180 ℃～200 ℃, make the power insulated wire cores that voltage withstand class reaches 6/10kV.
Afterwards, the wrapped one deck semi-conductive tape 5 of elder generation outside the power insulated wire cores, by metal knitted machine braiding one deck soft copper silk braid 6, count is not less than 80% again, and wire sheathing can prevent the electromagnetic interference of cable.
And the preparation process of control core is: pass through extruder extruded insulation layer 9 outside control line core conductor 8, producing linear speed is 15～20 m/mins, the extruder screw draw ratio is 14D, and extruder temperature is controlled at 50 ℃～80 ℃, and the curing tube temperature is controlled at 180 ℃～200 ℃.
To control core and optical cable 10 and be shaped by cabler, and middlely fill soft non-hygroscopic rope 11, outermost layer is with non-hygroscopic band 12 wrapped tightening.
With power core, control core and the fit parallel placement (such as Fig. 1) of groups of cables, use head and the mould of particular design to extrude polyurethane (TPU) outer jacket at φ 150 extruders, because TPU is the very easily moisture absorption of strong polar material, before sheathing, take to place hot air circular drying machine that 100 ~ 120 ℃ of dryings 4 hours are set raw material for this reason, guarantee that moisture is avoided owing to there being moisture to cause sheathing the mass defects such as pore to occur in the material below 0.05% among the TPU.The processing temperature of TPUE (TPU) is controlled at about 200 ℃, can guarantee that polyurethane (TPU) extrudes smooth surface, light.
Be placed on the both sides (such as Fig. 2) of cable according to the tensile elements of using needs can in cable, can increase by 13, two symmetries of tensile elements that formed by steel wire rope.
The concrete application approach of the utility model is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
