Background technology
Along with the fast development of China's economic construction, all trades and professions obtain and develop rapidly, particularly the industry such as electric power, communication, traffic, urban construction real estate obtains high speed development, in these industries, various cable is widely applied, and aluminium alloy cable has high strength and excellent antiseptic property and cheap price and is more and more subject to user and likes.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, improve 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, after particularly adding rare earth element, can crystal structure in fining metal conductor, thus greatly improve the conductance of conductor, heat-resisting quantity solves the problems such as conductor electrochemical corrosion simultaneously.Aluminium alloy cable is lightweight, and the weight in same conductor cross section is only 50% of copper conductor, and least less than copper by 40%, pliability is higher than copper by 25%, and cost ratio copper cable is low by 25%, and installation adapted can save 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, need further improvement, as conductor compacting, annealing technology does not pass a test, easily cause conductivity and resistance not up to standard, unreasonable structure, lack LSOH anti-flaming fire-resistance property, common place can only be used for, once breaking out of fire, cable can burn and cause generation pernicious gas, human body is damaged, also have existing optical fiber composite cable to there is optical fiber to be easily pulled off more, in signals transmission, the large and fiber-optic signal of loss is easily subject to again the current emissions of cable, affect communication quality, easily brittle in low temperature drying environment, cracking, phenomenon of rupture, be difficult to use in the presence of a harsh environment.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of Al-alloy cable, and cable has that volume is little, lightweight, superior flame retardant property, good flame retardation effect, the tension, creep, percentage elongation, conductance etc. of conductor are good, and have compressive property, long service life.
The technical solution adopted in the utility model is as follows:
A kind of Al-alloy cable, comprise the band set gradually outside multiple insulated wire cores and insulated wire cores, inner covering, armour and restrictive coating, packed layer is filled with between described insulated wire cores and band, described insulated wire cores is from inside to outside successively by aluminium alloy conductor, flame retardant coating and insulating barrier are formed, flame retardant coating is surrounded by outside described conductor aluminium alloy conductor, flame retardant coating is that two layers of two-sided mica tape overlap are wrapped, insulating barrier is surrounded by outside flame retardant coating, its insulating material adopted is LSOH anti-flaming cross-linked polyolefin, described aluminium alloy conductor is that rectangle cylinder aluminium alloy conductor is twisted into by a cylindrical aluminium alloy conductor and multiple cross section, described multiple cross sections are that the overall length of rectangle cylinder aluminium alloy conductor cross-sectional length equals cylindrical aluminium alloy conductor outside diameter, described aluminium alloy conductor is rare earth high-iron aluminum alloy conductor, between multiple insulated wire cores, gap is provided with high-temperature resistance carbon fiber composite material core bar, effect is equivalent to can not mutually disturb when dividing plate protects multiple insulated wire cores mutually to there will not be extruding phenomenon to ensure that it uses, improve the intensity of cable own simultaneously, described packed layer is that the free of contamination dustless mineral wool rope of high flame retardant is formed, described band is halogen-free low-smoke high-flame band, described inner covering material is halogen-free and low-smoke flame-retardant polyolefin oxygen barrier material, described armour is galvanized steel strip armouring, external sheath layer adopts cold resistance polyvinyl chloride or polyether polyurethane material extrusion moulding.
Described aluminium alloy conductor is that rare earth high-iron aluminum alloy conductor adopts AA8030 series aluminium alloy material, is twisted into compact conductor through impacted process and annealing in process.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model conductor is rectangle and a cross section by multiple cross section is that circular aluminum alloy conductor is by stranded formation conductor, improve tensile strength and the ampacity of conductor, between stranded aluminium alloy conductor, gap is little, same volume same material improves ampacity, make cable surface smooth simultaneously, improve anti-ice-snow function; Double-deck mica tape has good insulation property, hardness and water resistance, water-fast pouring and impact resistance; LSOH anti-flaming cross-linked polyolefin flameproof effect is good.Aluminium alloy conductor adopts the 8000 series alloys wires specified in ASTM B800-05 to substitute conventional copper product, so both can reduce costs, again can weight reduction, increase percentage elongation, compared with the copper conductor branch cable of replaceable specification, about gravity energy alleviates half.Between multiple insulated wire cores, gap is provided with high-temperature resistance carbon fiber composite material core bar; effect is equivalent to can not mutually disturb when dividing plate protects multiple insulated wire cores mutually to there will not be extruding phenomenon to ensure that it uses; improve the intensity of cable own simultaneously; external sheath layer adopts cold resistance polyvinyl chloride or polyether polyurethane material extrusion moulding; be convenient to that the cable cover(ing) avoiding causing in cold place is brittle, cracking, breakage problem, extend the useful life of cable in severe cold area.
