The beneficial effects of the utility model have:
1, owing to having adopted single line to press layer by layer as cable conductor bone piece, guarantee that the conductor body structure is stable, the bone piece pre-shaping device of moulding has guaranteed the uniformity of conductor diameter, the wrapped conductor screen embedded conductor of avoiding of semi-conductive tape causes electric field distortion, the wrapped nonwoven fabrics of outermost layer conductor, avoid conductor to pollute;
2, insulating barrier, owing to adopting 1000 grades of purified treatment gravity feeding devices, has guaranteed the degree of purification of material, so the excellent insulation performance of cable;
3, aluminium sheath anticorrosive coat tradition applies oven dry after adopting asphalt heating, and energy consumption is large, seriously polluted, and have potential safety hazard, we grope to adopt the asphalt caulk coating processes without the household through overtesting, have overcome the defect of traditional handicraft, energy-conserving and environment-protective, production efficiency is high;
4, oversheath adopts halogen-free low-smoke flame retardant material, safety and environmental protection.
The accompanying drawing explanation
Fig. 1 is conductor element sectional structure schematic diagram of the present utility model.
Fig. 2 is whole sectional structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
The utility model is a kind of high conductivity, comprehensive radial water-resisting/water proofing property, weatherability, and has cold-resistant, low temperature flexibility, and good electric property, tensile strength is high and the power transmission and distribution system power cable of the characteristics such as long service life.As shown in Figure 2, the center is conductor element 1 to its concrete structure, is surrounded by successively from inside to outside conductor shield 2, insulating barrier 3, insulation screen 4, semiconductive block water buffering belt 5, corrugated aluminum sheath 6 and oversheath 7 on conductor element 1.Insulating barrier 3 materials preferably adopt crosslinked polyethylene, and oversheath 7 materials preferably adopt environmental-protection flame-retardant low-smoke halogen-free polyolefin material.
As shown in Figure 1, the utility model 800mm
2And above copper core (1000mm
2And with upper aluminum core) conductor element 1 comprises the annular conduction assembly that five milliken conductors 101 form, in order to guarantee each strand of piece individual transmission electric current, five milliken conductors 101 are used thick 0.075～0.25mm each other, widely separate for the insulation crimped paper 102 of 47.0mm.Insulation crimped paper 102 is too wide too narrow all improper, does not normally want widely go out or be less than 1.0mm.The specification requirement of insulation crimped paper is: tensile strength is not less than 70N, and cross directional tensile is not less than 40N, and the longitudinal tensile strain rate is not less than 50%.The annular conduction assembly formed in order to tighten five milliken conductors 101 during stranding, adopting wrapped 3 layers of width is 50mm, the mode that thickness is the smooth semiconductive nylon tape 103 of 0.14mm plays the effect of uniform electric field simultaneously.After semiconductive nylon tape 103 is wrapped, require smooth must not wrinkling, flange, Duplication is 30%～50%, outer semiconductive nylon tape lap and internal layer semiconductive nylon tape lap are spaced apart.The semi-conductive tape joint should be firmly, the external diameter increase is as far as possible little.For dustproof and semiconductive nylon tape are avoided mechanical damage; wrapped 2 layers of nonwoven fabrics shape are nonwoven fabrics protective layer 104 again; after stranding, the large segment angle place of 5 milliken conductors 101 may form an annulus; in order to guarantee milliken conductor Stability Analysis of Structures, smooth surface rounding, stranded tight; can adopt external diameter to equate with internal radius or be slightly less than the conductor of internal radius or spill is filled, be i.e. conductor in Fig. 1 or spill obturator 105.But must guarantee external diameter and roundness after milliken conductor plying stranding.
The making of heavy in section five milliken conductors is very strict to equipment requirement, the utility model adopts GJ-630/1+6, JLK-630/12+18+24+30 frame type stranding machine and JPD-3150 dish strand formula cabler, transformation by the technical staff to equipment, but complete production heavy in section milliken conductor.Transform the gearratio of frame type stranding machine according to the transmission mechanics, and increased pre twist, be suitable for the strand system of milliken conductor thigh piece.Back-twist device and the draw-gear of dish strand formula cabler have been transformed, to be suitable for milliken conductor thigh piece plying stranding.The employing layering is pressed, and presses coefficient and can reach 86%～90%, and the outward appearance of compact conductor should be smooth, without bad defects such as burr, sharp edge, disconnected thighs.Carry out pretwist when pressing.Stranding is to complete on JPD-3150 dish strand formula cabler, and dish strand formula cabler has been installed position, automatic school device, can school card stranding process in the position of each strand of conductor, make it remain that same angle enters wire parallel module.In the conductor forming process, center adds the water blocking yarn of Φ 6～18mm to play the effect of conductor radial water-resisting waterproof.
Other undeclared part that the utility model relates to is same as the prior art.
