Abstract
The utility model relates to a low-voltage power cable with an aluminium alloy conductor. The low-voltage power cable comprises a cable conductor, an insulating layer and a protecting layer, and is characterized in that the cable conductor is formed by twisting heat-resistant aluminium alloy, the insulating layer is extruded outside the conductor, and the protecting layer is arranged outside an insulating core wire; the cable conductor is a heat-resistant aluminium alloy conductor, and the insulating layer can be formed by extruding insulating materials such as a polyvinyl chloride insulating material, a polyethylene insulating material or a cross-linked polyethylene insulating material; and the cable protecting layer can be an extruded single plastic protecting layer, or a steel-tape armoured composite protecting layer with an extruded plastic sheath. The low-voltage power cable disclosed by the utility model has the following advantages that: the conductor has the characteristics of being resistant to a high temperature of 150 DEG C, good in corrosion resistance, low in contact resistance, good in connection stability, light in weight, flexible in wire and high in strength, and has the advantages of being low in relative cost and relative stable in price; and compared with a common cable with an aluminium conductor, the allowable long-term working temperature of the cable can be increased to 150 DEG C from common 70 DEG C and 90 DEG C, and the current-carrying capacity of the cable can be greatly increased.
Description
Technical field
The utility model relates to a kind of aluminium alloy conductor lv power cable, belongs to the cable technology field.
Background technology
Current nonferrous metal price rises suddenly and sharply, and the copper conductor cost accounts for more than 90% of cable raw material total cost in low-voltage cable, and common aluminium conductor has easily oxidation of surface, and contact resistance is large, and the defect such as continue unstable.In order to reduce the application cost of cable, reduce the application of noble metal copper, can solve again simultaneously common aluminium conductor and have easily oxidation of surface, contact resistance is large, the defect such as continue unstable, adopt aluminium alloy conductor a kind of suitable selection of can yet be regarded as, the utility model has been developed a kind of aluminium alloy conductor lv power cable.
Summary of the invention
The purpose of this utility model is to solve cable main in the market of prior art to rely on the alternative expansion of copper and aluminium two large conductors, has proposed a kind of application of alternative cable conductor newly.Especially propose a kind of as the larger conductor material of application quantity in the agent structure of cable, in the situation that the nonferrous metal price fluctuation is larger, the cable price also can fluctuate larger, and adopt aluminium alloy conductor to have low, the with relatively stable price advantage of relative cost as conductor material, overcome the drawback that the copper material cost is high, price rises and fall sharply and quickly, solve aluminium conductor and had easily oxidation of surface, contact resistance is large, the defect such as continue unstable, the aluminium alloy cable price also can be relatively stable simultaneously, and the characteristic of heat-resisting aluminium alloy has also improved the bearing capacity of cable greatly.A kind of aluminium alloy conductor lv power cable of the utility model, comprise cable conductor 1, insulation 2, sheath 3, and it is characterized in that: cable conductor 1 forms by aluminium alloy is stranded, and cable conductor is extruded with insulating barrier 2 outward, and insulation core wire has sheath 3 outward.The aluminium alloy of cable conductor 1 is heat-resisting aluminium alloy.Insulating barrier 2 extrudes formation for polyvinyl chloride insulation material, insulating material of polyethylene or cross-linked polyethylene insulating material.The core quantity of cable conductor 1 can be 1 core, 2 cores, 3 cores, 4 cores, 5 cores or as 3+1 core, 3+2 core, the 4+1 core combining form by the big or small cable core of difference.The plastics single sheath of sheath 3 for extruding.Sheath 3 is the compound sheath with the extrusion plastic sheath of steel-tape armouring.The utlity model has following characteristics: the ⑴ conductor has can be high temperature resistant 150 ℃, good corrosion resistance, and conductor contact resistance is little, and the characteristics such as good stability continue; ⑵ cable is lightweight, line matter soft and the high characteristics of intensity; ⑶ aluminum alloy materials has low, the with relatively stable price advantage of relative cost; ⑷ compare with common aluminium conductor cable, and the long-term permission working temperature of cable can rise to 150 ℃ by common 70 ℃ and 90 ℃, can significantly improve the ampacity of cable.
