　　Guiyang Steel cored Aluminum Stranded Wire Manufacturer JL/G1A240/40 Sales Price Manufacturer Sales Welcome to Call

　　JL/G1A (LGJ) steel core aluminum stranded wire is one of the main products produced by our company. JL/G1A (LGJ) steel core aluminum stranded wire is made by twisting aluminum wire and steel wire. As the name suggests, the inside of the "LGJ steel core aluminum stranded wire" is a steel core, and the outside is wrapped around the steel core by twisting aluminum wire. The steel core mainly increases the tensile strength, while the aluminum wire mainly transmits electrical energy.

　　Steel cored aluminum stranded wire is made by twisting aluminum wire and steel wire, and is suitable for overhead transmission lines. It has a steel "core" inside and is wrapped around the steel core with aluminum wire twisted together on the outside; Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy;

　　Development prospects of JL/G1A (LGJ) steel cored aluminum stranded wire:

　　Currently, aluminum clad steel stranded wire (LGJ) is widely used as overhead conductors in China; Steel wire is used to transmit current, while aluminum wire is used to reduce corona and other losses. The cross-sectional area of the wire varies depending on the voltage. For example, currently the conductors of domestic 500 kV transmission lines are generally LGJ-240/40 conductors. L is the abbreviation for aluminum wire, G is the abbreviation for steel core, J is the abbreviation for stranded wire, 240 is aluminum 240 square millimeters, and 40 is steel 40 square millimeters. LJ is a bare aluminum wire without a steel core.

　　For high-voltage transmission lines, due to the limited path of the line and the impossibility of installing multiple lines on one path, people have come up with the method of using one path, one set of iron towers, and hanging multiple wires, that is, one line is equivalent to installing multiple lines; For 500KV transmission lines, China mostly adopts the method of hanging four wires, which is called the same tower parallel installation.

　　Steel cored aluminum stranded wire has the characteristics of simple structure, easy installation and maintenance, low line cost, large transmission capacity, and is conducive to laying across geographical conditions such as rivers and valleys. It has good electrical conductivity and sufficient mechanical strength, high tensile strength, and the tower distance can be enlarged. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
