Advantages of aluminum alloy cable tray

1、在同样体积下，铝合金的实际重量大约是铜的三分之一。采用铝合金电缆取代铜缆，可以减轻电缆重量，降低安装成本，减少设备和电缆的磨损，使安装工作更轻松。

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、导电性能：江苏阳刚电气设备有限公司的导电率是常用基准材料铜IACS的61.5o/o，载流量是铜的79o/o，优于纯铝标准。

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、抗蠕变性能：铝合金导体的合金材料与退火处理工艺减少了导体在受热和压力下的“蠕变”倾向，相对于纯铝，抗蠕变性能提高300%，避免了由于冷流或蠕变引起的变松问题。

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、抗拉强度和延伸率：铝合金导体相比于纯铝导体，由于加入了特殊的成分并采用了特殊的加工工艺，很大大的提高了抗拉强度，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、热膨胀系数：热膨胀系数用来计算在温度变化时材料的尺寸变化。铝合金的热膨胀系数与铜相当，多年来铝连接器一直可靠地用于铜和铝导体，且当今使用的大部分电气连接器都是用铝制造的，这尤其适合铝合金。所以铝合金导体与连接器的膨胀和收缩完全一致。

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、自重承载力强：铝合金改变了纯铝的抗拉强度，铝合金电缆可支撑4000米长度的自重，铜电缆只能支撑2750米。这种优势在大跨度的建筑（如体育场馆）配线时体现得尤为突出。

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).
