Abstract
A kind of novel aluminium alloy cable.Its conductor forms by the many aluminium alloy conductors containing rare earth and ferrous components are stranded, aluminium alloy conductor is outward the insulating barrier of silane crosslinked polyethylene composition, the flame retardant coating of the outer wrapped ceramic macromolecule composite fire silicon rubber composition of insulating barrier, flame retardant coating is outward the chain armour of aluminum alloy strip, and the chain armour of aluminum alloy strip is outward the oversheath of polyether-type TPU composition.Novel aluminium alloy cable has the good characteristics such as lightweight, high tensile, corrosion-resistant and fire prevention.
Description
Technical field
The field of cable technology that the utility model belongs to high temperature resistant, ampacity is large, especially has the aluminium alloy cable of superior function.
Background technology
At present, because copper has high conductivity, copper cable is large-scale application at home, but the cost ratio aluminium of copper is high a lot, with aluminium for copper to realize the more Optimum utilization of resource, the toughness of aluminium cable and antiacid caustic corrosion not enough.
To add the aluminum alloy materials of rare earth and ferrous components for conductor, adopt the new material power cable of the advanced technology innovation and creation such as the stranded production technology of the molded molded line of special roller and annealing in process.Aluminium alloy power cable compensate for the deficiency of fine aluminium cable in the past, although do not improve the electric conductivity of cable, but bending property, creep-resistant property and decay resistance etc. improve greatly, can ensure cable long term overloading and overheated time keep continuous stable performance, adopt AA-8030 series alloys conductor, greatly can improve conductance, the heat-resisting quantity of aluminium alloy cable, solve the problems such as the electrochemical corrosion of fine aluminium conductor, creep simultaneously.
Aluminium alloy cable generally needs to possess fire resistance, in the construction of heavy construction, aluminium alloy cable is general that span is large, and deadweight bearing capacity is strong, improve the fail safe of cable to reduce construction cost, convenient construction, aluminium alloy cable also must possess the mechanical properties such as high tensile simultaneously.
Summary of the invention
In order to improve the tension of existing aluminium alloy cable, fire-resistant, decay resistance, the utility model provides a kind of novel aluminium alloy cable, even if also can normally arrive a little and low smoke and zero halogen in the high fire of this novel aluminium alloy cable fail safe.
The utility model solves the technical scheme that its technical problem adopts: the conductor of novel aluminium alloy cable forms by the many aluminium alloy conductors containing rare earth and ferrous components are stranded, aluminium alloy conductor is outward the insulating barrier of silane crosslinked polyethylene composition, the flame retardant coating of the outer wrapped ceramic macromolecule composite fire silicon rubber composition of insulating barrier, flame retardant coating is outward the chain armour of aluminum alloy strip, and the chain armour of aluminum alloy strip is outward the oversheath of polyether-type TPU composition.
Aluminium alloy conductor containing rare earth and iron has high-flexibility, counter-bending, strong extension, creep resistant and acid-proof alkaline, and under identical ampacity, the weight of required aluminium alloy conductor is about the half of copper conductor, and the price of aluminium alloy conductor is low.
In the insulating barrier of silane crosslinked polyethylene composition, organosilane crosslinked polyethylene is a kind of network structure, even if this structure at high temperature has very strong non-deformability too, it has anti-aging and excellent insulation property.
Ceramic macromolecule composite fire silicon rubber is formed hard ceramic-like object after combustion and is had fire resistance, supports inner insulating barrier and conductor simultaneously.
Aluminium alloy armored layer is lower than the weight of steel-tape armouring, convenient-laying, what adopt is the chain armouring of aluminum alloy strip, its linkage structure between layers, ensure that cable can stand extraneous powerful destructive power, even if when cable suffers larger pressure and impulsive force, cable is also not easily breakdown, improves security performance.Sheathed structure makes cable be isolated from the outside simultaneously, even if when fire, armour improves the flame-retardant rank of cable.
The oversheath that polyether-type TPU forms has the good characteristics such as wear-resisting, corrosion-resistant, weatherability and environmental protection.
Beneficial effect of the present utility model is, novel aluminium alloy cable has the good characteristics such as lightweight, high tensile, corrosion-resistant and fire prevention.
