Aluminum stranded wire.
At present, China generally uses aluminum clad steel wire (LGJ) as the conductor, the steel core plays an increasing role in the strength, the main transmission power of aluminum wire. Depending on the voltage, the cross section area of the wire is also different. For example, the current domestic 500 thousand volt power transmission lines in general LGJ-400/35 of the wire. L is the abbreviation of G wire, steel core is referred to as J, is referred to as 400 strands, aluminum is 400 mm, 35 mm square steel is 35.
1 product profiles
The product is a material used for transmitting current, which is composed of a single layer or a plurality of non insulated wires around a central core. Mainly used for power transmission of overhead transmission lines, is one of the main products of the power grid.

4 Schematic diagram of product structure
5 the main technical parameters are changed to the scope of application of products:
The aluminum wire is suitable for less force in general distribution lines with the smaller distance.
The steel core aluminum stranded wire is simple in structure, set up and maintained conveniently, large transmission capacity, but also conducive to across rivers and valleys and other special geographical conditions and characteristics, so the products widely used in distribution lines in various voltage level of overhead transport.
The anti-corrosion type steel core aluminum stranded wire with good corrosion resistance, suitable for coastal saline lagoons, containing salt quality sand areas and industrial areas of high pressure, extra high voltage and common distribution line set.
