UL Certification for Aluminum Building Wire UL铝导体建筑线的认证
Requirements for Aluminum Alloy铝合金的要求
“AA-8000 series aluminum alloy is the only type of aluminum alloy permitted for use in UL listed building wire”
“AA-8000系列铝合金是唯一一种被UL允许使用于建筑线类的铝合金”
ASTM B800: 8000 Series Aluminum Alloy Wire 8000系列铝合金电线
Physical Properties 物理性能
• Minimum elongation 最小延伸率: 10%
• Minimum tensile strength (stranded) 最小抗拉强度 (绞合):
15,000~22,000 PSI (lbf/in2)
• Minimum tensile strength (solid) 最小抗拉强度 (实芯): 14,250~23,100 PSI (lbf/in2)
High-current Heat Cycling 大电流热循环
• <175oC measured by minimum 24 thermocouples由最少24个热电偶测量
• 40A, 60Hz, 50 cycles of operation 操作循环
• 1 cycle 循环 = 3.5 Hr ON + 0.5 Hr OFF
For further processing as insulated conductors employed in other listed cables, e.g. TC, MC 作为芯线进一步加工成为其他列名电缆, 如TC, MC
