1.抗蠕变性能 1. Creep resistance 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松弛问题。 Aluminum alloy conductor of alloy materials and annealing treatment reduced the conductor under heat and pressure of "creep" tendency, relative to the pure aluminum, creep resistance increased by 300%, to avoid the problems caused by cold flow or creep relaxation. 2.抗拉强度和延伸率 2. Tensile strength and elongation 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,极大的提高了抗拉强度,且延伸率提高到30%,使用更加安全可靠。 Because compared to aluminum alloy conductor in the pure aluminium conductor, joined the special ingredients and the special processing technology, greatly improved the tensile strength, and elongation increased to 30%, using more safe and reliable. 3.热膨胀系数 3. Thermal expansion coefficient 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。 The thermal expansion coefficient is used to calculate the size of the material when the temperature changes. The thermal expansion coefficient of aluminium alloy of copper and aluminum connectors for many years has been reliably used in copper and aluminium conductor, and most of the electrical connector in use today are made of aluminum, it is especially suitable for aluminium alloy. Therefore, the expansion and contraction of aluminum alloy conductor and connector are identical. 4.连接性能 4. Connection performance 用铝合金制造的电气连接与用铜导体制造的连接一样安全稳定。 铝合金的成分大大改进了其连接性能,当导体退火时,添加的铁产生高强度抗蠕变性能,即使在长时间过载和过热时,也能保证连接稳定。 Electrical connections made of aluminum alloy are as safe and stable as those made with copper conductors. Aluminum alloy components greatly improve the connection performance, when the conductor annealing, adding iron to produce high strength and creep resistance, even in a long time when overload and overheat, can guarantee the stability of connection. 5.自重承载力强 5. Self-weight bearing capacity is strong 铝合金改善了纯铝的抗拉强度,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。 Aluminum alloy improves the tensile strength of pure aluminum, aluminum alloy cable can support 4000 meters of self-weight, copper cable can only support 2,750m. This advantage is particularly evident in the wiring of large-span buildings such as stadiums.
