Stranded aluminum and ACSR (GB1179-83)
Uses: This product is applicable to use of overhead power lines.
Model and Name:

ACSR aluminum wire and the elastic coefficient and linear expansion coefficient:
Elasticity of aluminum wire and the expansion coefficient

The number of single-root	Elasticity final (actual value)		Linear expansion coefficient（1/⁰C）
The number of single-root	N/mm²	kgf/mm²	Linear expansion coefficient（1/⁰C）
7	59000	6000	23.0×10^–⁶
19	56000	5700	23.0×10^–⁶
37	56000	5700	23.0×10^–⁶
61	54000	5500	23.0×10^–⁶

Note：1, elastic coefficient for the accuracy of300N/mm2 (± 300kgf/mm2).

2, coefficient of elasticity for the force at 15% ~ 50% of break strength of aluminum wire.
