Technical field:
The utility model relates to a kind of heat-resistant ultraviolet ray aluminium alloy lv power cable.
Background technology:
Compared with traditional copper core cable, alloy cable is under the electric conductivity prerequisite suitable with copper, gentlier more pliable and tougher, thoroughly change fine aluminium cable machinery intensity difference in the past simultaneously, the shortcomings such as the low and joint of anti-fatigue ability is prone to accidents, in addition, also having made up traditional copper cable has the defect such as memory effect and high ballistic properties, has lowered line loss simultaneously and has saved the energy.
Alloy cable is installed and used the time that exceedes 35 years in North America.North America region and Chinese geographic latitude are close, and weather conditions are similar, and the successful Application under different temperatures/humidity/adverse weather condition can supply domestic complete reference.Nearly 5 years, alloy cable was in China, Beijing, and Tianjin, Jilin, Guangzhou, Hunan, Ningbo, Taiyuan, after the practical application of the multiple provinces and cities in Sichuan, repercussion is strong, and reflection is good.
At present, not only the passed through GB12706(IEC60502 the same as traditional copper cable of alloy cable that the Jia Lv company that makes every effort to open up of alloy cable occupation rate of market maximum produces) test, and pass through CSA C22.2No.51, " IEC60754-2 low smoke and zero halogen ", " IEC61034 dense smoke density measurement ", " test of burning class 4 Ji – vertical-rise cable crane span structure " etc.Novel alloy cable is progressively being come into people's the visual field, enters into and go each industry, is more and more approved.Can affirm, the foreseeable future, alloy cable must will occupy a consequence at electricity market, leads cable industry to cross over a new step.
China is again the country that a rich aluminium lacks copper, if can save copper with aluminium, rationally utilize bauxite resource, the science of China's abundant to select alloy cable, to under the prerequisite meeting cable electrical performance, greatly reduce engineering cost, in the power construction of China, produce huge economic benefit and environmental benefit.But, also do not have at present the one can heat-resisting and again can anti-ultraviolet aluminium alloy lv power cable.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of heat-resistant ultraviolet ray aluminium alloy lv power cable, it is that one had both possessed cost advantage, possesses again the heat-resistant ultraviolet ray aluminium alloy lv power cable of high-environmental performance and high flame resistance.
The utility model technical solution problem adopts following technical scheme:
A kind of heat-resistant ultraviolet ray aluminium alloy lv power cable, many insulated wire cores are twisted into cable core, be provided with packed layer in cable core gap, described insulated wire cores from-inner-to-outer is made up of conductor and insulating barrier, and described cable core and described packed layer are coated with the first belting layer, inner sheath, armour, the second belting layer and outer jacket outward successively; Described conductor is 8000 series alloys conductors.
Described insulating barrier is 125 DEG C of IXPE insulating barriers.
Described packed layer is low smoke, zero halogen inserts.
Described the first belting layer and the second belting layer are low smoke, zero halogen band.
Described inner sheath is ceramic silicone rubber jacket.
Described armour adopts aluminum alloy strip armouring.
Described outer jacket is LSOH anti-flaming uvioresistant polyolefin jacket.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, conductor adopts 8000 series alloys conductors, and it has the characteristics such as high creep resistance, high-tensile, high-elongation, deadweight bearing capacity is strong, Corrosion Protection is good, high-flexibility, simultaneously switching performance safety and stability.This utility model product conductor adopts the aluminium alloy of the 2nd class formation to press stranded conductor wire core, and stranded conductor wire core makes it have stronger tensile property.
2, insulating material adopts 125 DEG C of IXPE to make, and IXPE is after electron beam to irradiate crosslinked, and mechanical performance improves greatly, guarantees that cable has excellent electric property, mechanical performance.The long-time running temperature of cable is at 125 DEG C, and compared with common cable, the mechanical and physical performance of cable is good, and ampacity improves greatly, and rise appreciably useful life.
3, " ceramic silicon rubber " is a kind of novel polymer composite, does inner sheath can the breaking out of fire in the situation that, ensure the unimpeded of electric power, communication line with it, the not short circuit of 90-180min of working, opens circuit the in the situation that of flame ablation; Ceramic silicon rubber oxygen barrier layer makes cable have high flame resistance, and its fire resistance is up to state standards category-A bunched burning test requirement that GB/T19666-2005 specifies has ensured the fail safe that cable uses under fire condition.
4, armouring adopts the chain armouring of aluminum alloy strip, and its linkage structure between layers ensures that cable can stand extraneous powerful destructive power, even when cable suffers larger pressure and impulsive force, cable is also difficult for breakdown, has improved security performance.Sheathed structure is isolated from the outside cable simultaneously, even in the time of fire, armour has improved the flame-retardant rank of cable, has reduced the danger coefficient of fire.
5, outer jacket adopts environment-protective halogen-free low-smoke flame-retardant uvioresistant polyolefin jacket material, makes it have and under-40 DEG C of low temperature environments, keeps normal operation, adds light stabilizer in sheath, makes it have good light aging in resistance to day and Corrosion Protection.
6, all material of the utility model product all adopts LSOH anti-flaming material, has ensured cable loop guaranteed cost.Have when burning smoke density very low, non-corrosiveness gas is overflowed, and does not also produce harmful hydracid material, possesses the advantages such as low temperature resistant, uvioresistant, high flame resistance simultaneously, can be widely used in the place that some personnel relatively concentrate.
