Advantages of aluminum alloy cable tray

1、在同樣體積下，鋁合金的實際重量大約是銅的三分之一。采用鋁合金電纜取代銅纜，可以減輕電纜重量，降低安裝成本，減少設備和電纜的磨損，使安裝工作更輕松。

1. At the same volume, the actual weight of aluminum alloy is about one-third of that of copper. Using aluminum alloy cable instead of copper cable can reduce the weight of cable, reduce the installation cost, reduce the wear of equipment and cable, and make the installation easier.

2、導電性能：江蘇陽剛電氣設備有限公司的導電率是常用基準材料銅IACS的61.5o/o，載流量是銅的79o/o，優(yōu)于純鋁標準。

2. Conductivity: the conductivity of Jiangsu Yanggang Electrical Equipment Co., Ltd. is 61.5o/o of the common reference material copper IACS, and the current carrying capacity is 79o / O of copper, which is better than the standard of pure aluminum.

3、抗蠕變性能：鋁合金導體的合金材料與退火處理工藝減少了導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%，避免了由于冷流或蠕變引起的變松問題。

3. Creep resistance: the alloy material and annealing treatment process of aluminum alloy conductor reduce the "creep" tendency of the conductor under heat and pressure. Compared with pure aluminum, the creep resistance can be increased by 300%, avoiding the loosening problem caused by cold flow or creep.

4、抗拉強度和延伸率：鋁合金導體相比于純鋁導體，由于加入了特殊的成分并采用了特殊的加工工藝，很大大的提高了抗拉強度，且延伸率提高到30%，使用更加可靠。

4. Tensile strength and elongation: compared with pure aluminum conductor, aluminum alloy conductor greatly improves the tensile strength and elongation to 30% due to the addition of special components and special processing technology.

5、熱膨脹系數(shù)：熱膨脹系數(shù)用來計算在溫度變化時材料的尺寸變化。鋁合金的熱膨脹系數(shù)與銅相當，多年來鋁連接器一直可靠地用于銅和鋁導體，且當今使用的大部分電氣連接器都是用鋁制造的，這尤其適合鋁合金。所以鋁合金導體與連接器的膨脹和收縮完全一致。

5. Coefficient of thermal expansion: the coefficient of thermal expansion is used to calculate the dimensional change of materials when the temperature changes. Copper and aluminum alloys have been used for electrical connectors for many years, and most of them are suitable for aluminum and aluminum alloys. Therefore, the expansion and contraction of aluminum alloy conductor and connector are completely consistent.

6、自重承載力強：鋁合金改變了純鋁的抗拉強度，鋁合金電纜可支撐4000米長度的自重，銅電纜只能支撐2750米。這種優(yōu)勢在大跨度的建筑（如體育場館）配線時體現(xiàn)得尤為突出。

6. Strong self weight bearing capacity: aluminum alloy changes the tensile strength of pure aluminum. Aluminum alloy cable can support the self weight of 4000 meters, while copper cable can only support 2750 meters. This advantage is particularly prominent in the wiring of long-span buildings (such as stadiums and gymnasiums).
