Abstract
The utility model discloses a strenghthened type aluminum alloy resistance to compression cable, including tubulose aluminum alloy conductor, be equipped with the compound core of strengthening of carbon fiber at tubulose aluminum alloy conductor's center, be equipped with the thin copper area between compound enhancement core of carbon fiber and tubulose aluminum alloy conductor, extruded insulation layer outside tubulose aluminum alloy conductor, the winding comprises on the single line layer that forms of winding side by side many conductive single wire outside the insulating layer, around package buffer layer and oversheath outside the single line layer, still be equipped with metal pressure -resisting pipe between buffer layer and oversheath, the utility model discloses having compressive strength height, mechanical strength, high, dampproofing and the leakproofness is good, the bendability is good, the cost is reduced, prolonged life.
Description
Technical field
This utility model relates to field of cables, especially a kind of reinforced aluminium alloy Compression-resistincable cable.
Background technology
It is known that the aluminium alloy cable of routine generally adopts AA8000 series alloys twisted wire as conductor, constitute at the outer extruded insulation layer of conductor, and the tenacity of aluminium alloy cable is 53MPa, well below the 70MPa of copper conductor cable; It occur frequently that situation about breaking in using.
Prior art dish adopts bracing frame that cable is supported; coaxial cable is protected by increasing the form of bracing frame; there is certain effect; but add laid down cost and time; in addition the load-carrying properties of cable own are poor, unavoidably can because operation causes the problem that the core of cable damages accidentally in work progress.
In recent years, improvement, it is well recognized that the deficiency of this aluminium alloy cable self, is all constantly being explored by cable enterprise.
Utility model content
This utility model is in that to provide a kind of comprcssive strength height, mechanical strength height, protection against the tide and good airproof performance, good bandability, reduces cost, extends the reinforced aluminium alloy Compression-resistincable cable in service life.
For solving above technical problem, the reinforced aluminium alloy Compression-resistincable cable of one described in the utility model, including tubular aluminum alloy conductor, it is provided with carbon fiber compound reinforced core at the center of tubular aluminum alloy conductor, between carbon fiber compound reinforced core and tubular aluminum alloy conductor, is provided with thin copper belt; At the outer extruded insulation layer of tubular aluminum alloy conductor, outside insulating barrier, it is wound around the single line layer being entwined side by side by many conduction single lines constitutes; At the outer wrapped cushion of single line layer and oversheath; Metal compression tube it is additionally provided with between cushion and oversheath.
Described carbon fiber compound reinforced core is closed by many fine carbon compound tow or stranded forms.
Described metal compression tube is the hard compression tube of wrapped or vertical bag.
This utility model waterproof armored cable beneficial effect will be in:
1, the tensile strength enabling aluminum alloy to cable self increases to the level suitable with prismatic copper conductor, effectively solves the problem that cable is pulled off;
2 compared with copper cable, reduces material cost, has saved copper resource; Compared with aluminium cable, add the index such as tensile strength, heat stability; Substantially prolongs the safe operating life of cable;
3, between cushion and oversheath, metal compression tube it is additionally provided with so that the mechanical strength of cable is high, compressive property is good, moistureproof and good airproof performance, embossing can improve its bending property;
4, described single line layer is equivalent to an outer conductor so that inner and outer conductor is in concentric position, and electromagnetic energy is confined to the media between internal and external conductor, therefore has decay little, and shielding properties is high;
5, tubular inner conductor is adopted can to save metal material, alleviate cable weight, under high-power, high frequency, due to kelvin effect, electric current is actually simply along the laminar flow that conductive surface is very thin, tubular inner conductor pipe thickness is bigger than the skin depth of electric current, and its radio-frequency resistance is actually just the same with solid conductor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figure 1, the reinforced aluminium alloy Compression-resistincable cable of one of the present utility model, including tubular aluminum alloy conductor 3, it is provided with carbon fiber compound reinforced core 1 at the center of tubular aluminum alloy conductor 3, the tensile strength enabling aluminum alloy to cable self increases to the level suitable with prismatic copper conductor, effectively solves the problem that cable is pulled off; Thin copper belt 2 it is provided with between carbon fiber compound reinforced core 1 and tubular aluminum alloy conductor 3; At the outer extruded insulation layer 4 of tubular aluminum alloy conductor 3, constitute at the outer single line layer being entwined side by side by many conduction single lines 5 that is wound around of insulating barrier 4; At the outer wrapped cushion 6 of single line layer and oversheath 8; Being additionally provided with metal compression tube 7 between cushion 6 and oversheath 8 so that the mechanical strength of cable is high, compressive property is good, moistureproof and good airproof performance, embossing can improve its bending property.
The manufacture method of the reinforced aluminium alloy cable of this utility model, be carbon fiber complex core is placed on stranded conductor center or and twisted layer in optional position, this compound reinforced core can be solid, can be that many fine carbon compound tow close or stranded form, carbon fiber wire can be placed on a fixed position, it is possible to as required many fine carbon composite filament dispersions is placed on different positions (being such as dispersed to the gap place that monofilament is stranded); It is further continued for stranded aluminium alloy monofilament, the strand of aluminium alloy monofilament adjacent layer is to should be contrary, conductor resistance and other electric requirement can be determined by the filament diameter of aluminium alloy conductor and monofilament radical according to power system or meet in relevant criterion, last extruded insulation layer realizes the good combination between carbon fiber compound reinforced core and aluminium alloy monofilament, realizes aforementioned invention purpose.
Above-mentioned is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvement and adjustment, these improve and adjust and also should be regarded as protection domain of the present utility model.
