Abstract
The invention provides an aluminium alloy cable which comprises an insulated cable core and a heat-insulation flame-retarding reinforcement layer, a metal jacket layer, a bituminous coating layer and a sheath layer, which are arranged on the insulated cable core from the inside out in sequence. The insulated cable core is formed by a plurality of aluminium alloy wires and a cross-linked polyethylene insulating layer wrapped on the surfaces of the aluminium alloy wires. The Aluminium alloy cable overcomes the defects in the aspects of conductor processing, halogen-free low-smoke flame retardation, fire-resistant performance and anticorrosion and the like, and thus comprehensive protection performance of the cable is improved.
Description
Technical field
The present invention relates to field of cable technology, specifically, relate to a kind of aluminium alloy cable.
Background technology
Along with the fast development of China's economic construction, current China public place and skyscraper cable used are all copper core conductor low-smoke low-halogen or low-smoke halogen-free inflaming-retarding cable substantially, copper resource belongs to short goods and materials in China, but bauxite resource and rare earth resources are comparatively abundant, utilizing the materials such as aluminium alloy to make high performance cable can as the good solution of one, aluminium alloy cable adds the multiple elements such as copper, iron, silicon and rare earth in original metallic conductor aluminium, adopts a kind of cable that the advanced technologies such as special impacted process and annealing in process obtain.Aluminium alloy cable compensate for the deficiency of fine aluminium cable in the past, improves the electric conductivity of cable, bending property, creep-resistant property and decay resistance etc., can ensure cable long term overloading and overheated time keep continuous stable performance.There is certain problem in existing aluminium alloy cable, needs further improvement, and as conductor compacting, annealing technology do not pass a test, easily causes conductivity and resistance not up to standard; Unreasonable structure, lacks LSOH anti-flaming fire-resistance property, once breaking out of fire, cable can burn and cause generation pernicious gas, damages human body; Meet the need of market so its various performance should be promoted further to aluminium alloy cable.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.

Described aluminium alloy conductor is formed by many aluminium alloy pressings, forms a cylindrical aluminium alloy conductor bundle.
Described insulated wire cores cross section to be solidly fan-shapedly put together by multiple.
Prepare a method for above-mentioned aluminium alloy cable, specifically comprise the following steps:
By the described cross-linked type polyethylene insulating barrier of machinery parcel on many described aluminium alloy conductor bundles, thus obtained described insulated wire cores;
The heat-insulating flame-retardant reinforced layer that described insulated wire cores outer surface utilizes basalt fibre strap to strengthen by parcel one deck, forms basalt fibre strap heat-insulating flame-retardant reinforced layer;
Outside described basalt fibre strap heat-insulating flame-retardant reinforced layer, by parcel one deck wrinkle aluminium alloy, thus form metal jacket; At described metal jacket outer surface by parcel one deck bituminous coating, thus avoid the oxidation of described metal jacket;
Adopt cable extruding machine to be wrapped on described bituminous coating by low-smoke halogen-free flame-retardant isolating material, be squeezed into described restrictive coating, thus obtained described aluminium alloy cable.
Hinge structure of the present invention has outstanding substantive distinguishing features and significant progress, specifically, aluminium alloy cable of the present invention adopts the insulated wire cores be made up of multiple solid sector structure, the fan-shaped of different angles can be adopted according to the core number of different size cable and cross section, make its cable core structure stability better, and the course of processing is easy to control; Be provided with the heat-insulating flame-retardant reinforced layer that basalt fibre strap is strengthened on described insulated wire cores surface, thus improve high temperature resistant, the fire resistance of cable.
Further, wrinkle aluminum alloy sleeve is also enclosed with outside described basalt fibre strap heat-insulating flame-retardant reinforced layer, make described insulated wire cores and the external world completely isolated, improve the fire resistance of cable, effectively can avoid the fire incident because cable gas fire occurs, and cable also not easily punctures, improve the security performance that cable uses, also bituminous coating is coated with outside described wrinkle aluminum alloy sleeve, described bituminous coating outer surface wraps up one deck low-smoke halogen-free flame-retardant sheath, described wrinkle aluminum alloy sleeve can be made to be protected by this kind of structure, avoid corrosion and oxidation, described wrinkle aluminum alloy sleeve and described low-smoke halogen-free flame-retardant sheath can also be made to reach the effect of combining closely.Further say, described low-smoke halogen-free flame-retardant sheath have employed low-smoke halogen-free flame-retardant isolating material, has certain fire retardation, nontoxic, the low cigarette of the gas of releasing during cable fire.
