Steel Core Aluminum Stranded Wire  
Characteristic:：
1、Steel core aluminum stranded wire has the advantages of simple structure, convenient erection and maintenance, line of low cost, transmission of large capacity.
2、Favours the laying of the special geographical conditions across rivers and valleys.
3、Have the characteristics of good electric conductivity and sufficient mechanical strength, high tensile strength, enlarded pole distance.

Representation Method:
Steel core aluminum stranded wire is used in GB 1179-83 standard, the product is represented by the model, specification and the standard number.
The nominal cross of steel core aluminum stranded wire is that aluminium is 300mm2,steel is 50 mm2 ,expressed as:LGJ—300/50 GB 1179—83

Material:
Galvanized steel wire should comply with the standard of GB3428 – 82 “Galvanized Steel Core Wires for Steel core aluminum stranded wire”

Structure:
Aluminum and steel wire of steel core aluminum stranded wire in the root number and nominal diameter should be consistent with the provisions of table (specification).
The diameter ratio of any ground layer of aluminium wire or steel wire should not be greater than the adjacent inner layer.
The stranding direction of adjacent layers to be on the contrary, the outermost for aluminum twisted to the right.
