五、导线的使用特性
1、NRLH10GJ钢芯耐热铝合金导线长期工作温度150℃。
2、适用架空导线的特高强度钢芯耐热铝合金导线采用进口高强度钢芯，可使导线在150℃时的应力全部集中在钢芯上，使得导线线芯不破坏，导线孤垂不会因温度升高而加大。
3、与同截面的普通钢芯铝绞线相比，耐热铝合金导线150℃时的载流量比普通钢芯铝绞线载流量提高50%以上。
4、由于耐热合金导线具有较好的载流特性，故在旧线路和特殊地区的换线中，可采用同等规模、截面的耐热合金导线，在不改变铁塔等的情况下，实现增容一倍的效果，使得导线具有较大的经济性和适用性。
5、在特殊高寒地区，可用此导线作为熔冰导线，确保电力畅通。
Using properties
1 The continuous operating temperature of type NRLH10GJ is 150℃.
2 The high tensile strength steel core used for overhead power line is imported from abroad. 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.
