When the total stress is concentrated inside the steel core at 150?, the arc of the conductor will be protected in good order. 3 The current capacity of Heat Resistance Aluminum Alloy Conductor is about 50% higher than that of ACSR in the same sectional area. 4 For its good current capacity, Heat Resistance Aluminum Alloy Conductor is widely used for reform the old line and in some special areas. The current capacity will be doubled. 5 In some extra cold areas, the conductor is used of melting ice power line. 附表:耐热铝合金圆线性能参数 Appendix: Characteristic of Thermo-resistance Aluminum Alloy Conductor 项目 NRLHGJ 10Item 2抗拉强度(N/mm) 150,168 Tensile strength 断裂伸长率(%) 1.5 Elongation 电导率(%IACS) 60 Conductivity 电阻温度系数20?(1/?) 0.00397 Coefficient of resistance/ temperature 2弹性系数(N/mm) 70000 Modulus of elasticity -6线膨胀系数(10/?) 23.0 Coefficient of linear expansion 强度残存率不小于(%) 90 Minus survivals of strength
