Steel-core aluminum stranded wire

1. Product name: steel core aluminum stranded wire

2. Executive standard: GB/T 1179-2017 round wire concentric stranded overhead wire

3. Product introduction: refers to the reinforced wire of single-layer or multi-layer aluminum strands stranded outside the galvanized steel core wire. It is a steel "core" inside, and an aluminum wire is wound around the steel core by stranding on the outside; the steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy;

4. Product features: This product has the characteristics of simple structure, good conductivity and sufficient mechanical strength, high tensile strength, convenient erection and maintenance, low line cost, and large transmission capacity.

5. Scope of application: It is suitable for large-span overhead fixed laying, and is conducive to laying across special geographical conditions such as rivers and valleys, so it is widely used in overhead transmission and distribution lines of various voltage levels.

6. Symbol Description:

Concentric Stranding – J

Aluminum wire – L, L1, L2, L3

Steel cores – G1A, G2A, G3A
