Description

A kind of High-performance aluminium alloy cable

Technical field

The utility model is related to field of cables, more particularly to a kind of High-performance aluminium alloy cable.

Background technology

At present, China enters Electrification Age comprehensively, and cable usage amount is increasing, manufactures the main material of cable conductor Material is copper, accounts for national total copper consumption 70% or so, but China's copper resource is very short, and 80% copper needs import, and dependence is big, by This enables aluminum alloy to cable and is developed.In the case of equal current-carrying capacity, aluminium alloy cable weight is the half of copper core cable, its Sectional area is 1.1~1.25 times of traditional copper core cable, and price is lower than traditional copper core cable by 15~30%, and copper valency is continuous Soaring to make to turn into the inexorable trend that electric wire develops with aluminium section copper, aluminium alloy power cable has good mechanical performance and electricity Performance, can be applied to the electric power systems such as skyscraper, tunnel, subway, highway, colliery.

Aluminium alloy cable has excellent decay resistance, mechanical performance, conductive capability and creep-resistant property, but not Under with occasion, the requirement to cable performance is also different, therefore it provides high performance aluminium alloy cable is to following aluminium alloy cable Development also seems particularly necessary.

The content of the invention

The purpose of this utility model is to provide a kind of High-performance aluminium alloy cable, and it has Effectiveness of Low Frequency Electromagnetic Shielding.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of High-performance aluminium alloy cable, including cable core, are coated on the lapping layer outside cable core, be coated on outside lapping layer every Thermosphere, is coated on the armor outside thermal insulation layer, is coated on the restrictive coating outside armor；The cable core includes three cores, described Packed layer is provided between core and between core and lapping layer, the packed layer is filled out using rope and low thermal resistance mineral material is strengthened Fill；It is characterized in that：The core includes conductor, the low frequency electromagnetic screen layer being coated on outside conductor, is coated on low-frequency electrical magnetic cup The insulating barrier outside layer is covered, the proof copper-wire braided screen layer outside insulating barrier is coated on, the silicon rubber outside proof copper-wire braided screen layer is coated on Insulating barrier；The conductor using many circular aluminium alloy single-core lines it is stranded press form, the low frequency electromagnetic screen layer is two-layer Iron-silicon-boron alloy film coated is constituted outside conductor.

Preferably, the insulating barrier is extruded in outside low frequency electromagnetic screen layer by XLPE crosslinked polyethylenes and constituted.

Preferably, the armor is steel-tape armouring.

Preferably, the restrictive coating is low-smoke halogen-free polyolefin sheath.

The utility model beneficial effect be that a kind of High-performance aluminium alloy cable sets low frequency electromagnetic screen in conductor peripheral hardware Layer and proof copper-wire braided layer are covered, both there is good shielding to high-frequency electromagnetic, under low frequency electromagnetic environment, and with low frequency electromagnetic Shielding properties；Conductor core wire structure is in press circle, it is possible to increase conductive stability and conductance；Employed in packed layer low Thermal resistance mineral material, can eliminate the harmful effect that closed air radiates to cable in poling, effectively lift current-carrying capacity of cable.This Utility model simple structure, possesses general aluminium alloy cable performance, enhances capability of electromagnetic shielding, electric conductivity and thermal diffusivity Energy.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

1 the utility model is expanded on further below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of High-performance aluminium alloy cable of the utility model, including cable core, it is coated on wrapped outside cable core Layer 5, is coated on the thermal insulation layer 6 outside lapping layer 5, is coated on the armor 7 outside thermal insulation layer 6, and armor 7 can be steel-tape armouring, Can also be aluminum alloy strip armouring, the also restrictive coating 8 with low-smoke halogen-free polyolefin material including being extruded in outside armor 7；Cable Core includes three cores, and packed layer is provided between core and between core and lapping layer, and packed layer uses reinforcement rope 9 and low thermal resistance Mineral material 10 is filled, and can eliminate the harmful effect that closed air radiates to cable in poling, effectively lifts current-carrying capacity of cable, There is good anti-flammability again simultaneously；

The core includes conductor 1, the low frequency electromagnetic screen layer 2 being coated on outside conductor 1, is coated on low frequency electromagnetic screen layer The crosslinked polyetylene insulated layers 3 of XLPE outside 2, are coated on the proof copper-wire braided screen layer 4 outside insulating barrier 3, are coated on proof copper-wire braided screen Cover the silicone rubber insulation layer outside layer 4；Conductor 1 using many circular aluminium alloy single-core lines it is stranded press form, with circular configuration phase Than compression rear stability is good, and conductance is high；Low frequency electromagnetic screen layer 2 can be extruded in outside conductor 1 for iron-nickel alloy, preferably Way is using two-layer iron-silicon-boron alloy film coated outside conductor 1, in addition, can be with using iron-silicon-boron alloy film coated It is that two-layer can also be one layer, makes cable that not only there is good shielding to high-frequency electromagnetic, under low frequency electromagnetic environment, has again There is Effectiveness of Low Frequency Electromagnetic Shielding.
