钢芯耐热铝合金绞线
使用范围：Usage Scope
产品主要用于固定架空敷设交（直）流高、低压输配电力线路，导线传输容量（载体量）高，特别适用于窄通道、高容量输电及旧电网扩容改造工程。
The product is used for fixing and overhead construction of AC(DC), High/Low Voltage electric transmission line with high transmission capacity or load capacity. It is particularly for electric transmission of narrow channel and high capacity and transformation project of old electric network expansion
钢芯耐热合金导线（NRLH58GJ NRLH60GJ ）及特轻型钢芯铝绞线(LGJQT)，广泛应用于220kv -1000kv以上变电站工程，该导线加入合金成分，提高了产品的高温性能，
导线截面大，载流量增加，耐热温度高，导电率高，损耗小，降低了电能损耗，增加了设备运行的安全性能。安装，维护与普通导线安装程序相同，不需要任何特殊工具，
工装，安装，维护方便，成本低。
