Abstract
The utility model provides an aluminum alloy cable, including insulation core with set up on insulation core by the interior and outer basalt fiber cloth area that distributes insulate against heat fire -retardant enhancement layer, wrinkle aluminum alloy jacket layer, bitumen coating, the fire -retardant restrictive coating of low smoke and zero halogen, insulation core is restrainted and is wrapped up many by many aluminium alloy wire the cross -linking type polyethylene insulation that aluminium alloy wire restrainted the surface constitutes. The utility model overcomes cable not enough in conductor processing, in the aspect of not having steamed low cigarette performance such as fire -retardant, fire -resistant has strengthened the cable and has synthesized and protect the characteristic.
Description
Technical field
The utility model 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, all trades and professions obtain and develop rapidly, particularly electric power, communication, traffic, the industries such as urban construction real estate obtain high speed development, in these industries, various cable is widely applied, in current wires and cables industry, leading products are copper core cables, this cable cost of material is high, shortage of resources, and 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 copper in original metallic conductor aluminium, iron, the multiple element such as silicon and rare earth, adopt 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.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides that a kind of manufacture craft is simple, reasonable in design and the good aluminium alloy cable of insulated heat performance.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of aluminium alloy cable, comprise insulated wire cores and be arranged on basalt fibre strap heat-insulating flame-retardant reinforced layer, wrinkle aluminium alloy jacket layer, bituminous coating, low-smoke halogen-free flame-retardant sheath layer that insulated wire cores distributes from inside to outside, described insulated wire cores is made up of many aluminium alloy conductor bundles and the cross-linked type polyethylene insulating barrier being wrapped in many described aluminium alloy conductor bundle surfaces.
Described insulated wire cores cross section is multiple to be solidly fan-shapedly put together.
Described aluminium alloy conductor bundle is formed by many aluminium alloy pressings, forms a cylindrical aluminium alloy conductor bundle.
Described heat-insulating flame-retardant reinforced layer is made up of basalt fibre strap reinforcement material.
Described metal jacket is made up of wrinkle aluminum alloy materials.
The utility model hinge structure has substantive distinguishing features and progress, specifically, aluminium alloy cable described in the utility model adopt by multiple solid sector structure form insulated wire cores, 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.
