Description
Technical field
The utility model relates to a kind of cable, particularly a kind of aluminium alloy cable.
Background technology
Fast development along with China's economic construction; All trades and professions have obtained developing rapidly; Particularly industries such as electric power, communication, traffic, urban construction real estate have obtained high speed development; Various cables have obtained extensive use in these industries, and the aluminium alloy cable has high strength and good corrosion prevention performance and cheap price more and more to be received the user and like.
The aluminium alloy cable is in original metallic conductor aluminium, to add multiple elements such as copper, iron, silicon and rare earth, a kind of cable that adopts advanced technologies such as special impacted process and annealing in process to obtain.The aluminium alloy cable has remedied the deficiency of fine aluminium cable in the past; Electric conductivity, bending property, creep-resistant property and the decay resistance etc. of cable have been improved; Can guarantee that cable keeps continuous stable performance at long term overloading with when overheated; After particularly adding rare earth element, the crystal structure in can the fining metal conductor, thus the conductance, the heat-resisting quantity that improve conductor have greatly solved problems such as conductor electrochemical corrosion simultaneously.
The aluminium alloy cable is in light weight, and the weight in same conductor cross section is merely 50% of copper conductor, and bounce-back property is littler by 40% than copper, and pliability is higher by 25% than copper, and price is lower by 25% than copper cable, and the installation adapted can be saved more than 20%.Meet the fundamental state policy that China " builds a conservation-minded society ", meet " "four news" (new ideas " principle of architectural engineering.
There is certain problem in existing aluminium alloy cable, needs further improvement, and does not pass a test like conductor compacting, annealing technology; Cause conductivity and resistance not up to standard easily, unreasonable structure lacks the LSOH anti-flaming fire-resistance property; Can only be used for common place, in case breaking out of fire, cable can burn and cause the generation pernicious gas; Human body is damaged, meet the need of market so should further promote its various performances to the aluminium alloy cable.
The utility model content
The utility model technical problem to be solved provides a kind of rational in infrastructure, and fire resistance is the aluminium alloy cable more comprehensively.
In order to solve above-mentioned technical problem; The technical scheme of the utility model is: a kind of aluminium alloy cable, comprise band, inner covering, armour and restrictive coating that insulated wire cores and insulated wire cores set gradually outward, and be filled with packed layer between said insulated wire cores; Said insulated wire cores is made up of aluminium alloy conductor, flame retardant coating and insulating barrier from inside to outside successively; Said insulating layer material is the LSOH anti-flaming cross-linked polyolefin, and said band is a low smoke, zero halogen high flame retardant band, and said inner covering material is a halogen-free and low-smoke flame-retardant polyolefin oxygen barrier material; Said armour is the galvanized steel strip armouring, and said restrictive coating adopts halogen-free and low-smoke flame-retardant polyolefin sheathed material.
Said aluminium alloy conductor is a rare earth high ferro aluminium alloy conductor.
Said flame retardant coating is made up of two stratus master tapes.
The packing material of said packed layer is LSOH anti-flaming glass rope.
The utility model has overcome the deficiency of cable at conductor processing, LSOH anti-flaming, aspect of performance such as fire-resistant, has strengthened cable integrated protection characteristic, satisfies the various performances and the adaptability of aluminium alloy cable.The aluminium alloy conductor of the utility model is the circular compact conductor of rare earth high ferro aluminium alloy, and this conductor is through stranded impacted process and special annealing in process, and the extruding in the alloy aluminum is totally reduced sectional area, makes cable have pliability preferably; Between conductor and insulating barrier, be provided with two stratus master tapes, increased the fire resistance of cable, it is safer that cable is used; Inner covering adopts and extrudes halogen-free and low-smoke flame-retardant polyolefin oxygen barrier material; Improved the cable-flame retardant fire resistance rating; The galvanized steel strip armouring has strengthened the anti-extrusion ability of cable; Restrictive coating adopts halogen-free and low-smoke flame-retardant polyolefin sheathed material, has strengthened cable integrated protection characteristic, and the various performances of cable are significantly improved.
