四、鋁合金電纜的優(yōu)異特性
抗蠕變性能-鋁合金導(dǎo)體的合金材料與退火處理工藝減少了導(dǎo)體在受熱和壓力下的“蠕變"傾向，相對于純鋁，抗蠕變性能提高300%，避免了由于冷流或塘變引起的松弛問題。
熱膨脹系數(shù)-鋁合金的熱膨脹系數(shù)與銅相當(dāng)，基本上與連接器的膨脹和收縮一致。連接性能-用鋁合金制造的電氣連接與銅導(dǎo)體制造的連接一樣安全穩(wěn)定，鋁合金的成分大大改進了其連接性能，當(dāng)導(dǎo)體退火時，添加的鐵產(chǎn)生高強度抗蠕變性能，即使在長時間過載和過熱時，也能保證連接穩(wěn)定。
自重承載力強-鋁合金改善了純鋁的抗拉強度，鋁合金電纜可支撐4000米長度的自重，銅電纜只能支撐2750米防腐蝕性能-鋁合金在空氣中很快形成一層厚度約為
2x10-4mm%的緊密氧化膜，防止內(nèi)部的金屬被進一步腐蝕，而銅則不能形成氧化膜，特別是連接點產(chǎn)生的電化學(xué)腐蝕，鋁合金的抗腐蝕性能優(yōu)于銅。
柔韌性-鋁合金的合金配方、加工工藝，使柔韌性大幅提高。鋁合金比銅柔韌性高30%。
彎曲性能-純鋁電纜彎曲性能很差，彎曲很容易發(fā)生斷裂、折斷，鋁合金反彈性比銅低40%，在安裝過程中更容易彎折，有效的減少安裝成本，降低事故風(fēng)險。
鎧裝特性-鋁合金鎧裝電纜彎曲性能好，最小彎曲半徑優(yōu)于銅;機械強度高，具有抗張性能、抗壓性能和抗沖擊性能:防蟲蟻、老鼠咬:重量輕，更易安裝。
The excellent properties of aluminum alloy cable
Creep resistance of aluminum alloy conductor alloy materials andannealing treatment reduced the conductor under heat and pressure of"creep" tendency, relative to the pure aluminum, creep resistance increasedby 300%, to avoid the problems caused by cold flow or creep relaxation.
Thermal expansion coefficient of thermal expansion coefficient ofaluminium alloy and copper, basically are in complete accord with theexpansion and contraction of the connector.
The electrical connection in the connection performance - made ofaluminum alloy with copper conductor manufacturing as security andstability of the connection, the composition of aluminum alloy greatlyimprove the connection performance, when the conductor annealing.adding iron to produce high strength and creep resistance, even in along time when overload and overheat, can guarantee the stability ofconnection.
Weight bearing capacity is strong, aluminum alloy improved thetensile strength of pure aluminum, aluminum alloy of every cable cansupport 4000 meters in length, the copper cable can support 2750 meters.
Anti-corrosion performance - aluminum alloy in air quickly form athickness of about 2 x 10-4 was compact oxidation film, prevent theinternal metal was further corrosion, and copper could not form oxidationfilm, especially the connection point.
Electrochemical corrosion, the corrosion resistance of aluminumalloy is better than that of copper. Flexibility - aluminum alloy unique alloyformula and processing technology, to improve the flexibility. Aluminumalloy flexibility is 30% higher than copper.
Bending performance - the bending performance is very poor, purealuminum bending is easy to break, break, aluminum alloy is lower thancopper 40%, elasticity during the installation process easier to bendeffectively reduce the installation cost, reduce the risk of accidents.
Armoured features - aluminum alloy armoured cable bendingperformance is good, the smallest bending radius is better than that ofcopper; High mechanical strength, tensile properties, compressiveproperties and impact resistance; Insect-resistant ant, mice bite; Lightweight, easier to install
