Huizhou Steel Core Aluminum Stranded Wire Manufacturer Overhead Line

Description :

　　Steel cored aluminum stranded wire, abbreviated as "LGJ", is composed of aluminum wire and steel wire twisted together, and is mainly used for overhead transmission lines, similar to ordinary aluminum stranded wire "LJ". The inner part of steel cored aluminum stranded wire is a steel "core", and the outer part is wrapped around the steel core by twisting aluminum wire; Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy. Both belong to bare wires and have essentially the same purpose, but differ in their model and specification representation methods.

　　Ordinary aluminum stranded wire: The model is represented by "L J" and belongs to bare wire. At present, aluminum clad steel wire (LGJ) is widely used as the conductor in China, with the steel core mainly used to increase strength and the aluminum wire mainly used for transmitting electrical energy. The cross-sectional area of the wire varies depending on the voltage. For example, currently, LGJ-400/35 conductors are commonly used for 500 kV transmission lines. Among them, L is the abbreviation for aluminum wire, G is the abbreviation for steel core, J is the abbreviation for stranded wire, 400 is aluminum 400 square millimeters, and 35 is steel 35 square millimeters.

　　[Model meaning]: For example, GB1179-83 "Aluminum stranded wire" is an aluminum stranded wire with a nominal cross-section of 240 square millimeters.

　　The specification and model can be represented as: L J-240 GB1179-83

　　GB1179-83 "Steel cored aluminum stranded wire" with a nominal cross-section of 300 square millimeters for aluminum and 50 square millimeters for steel.

　　The specification and model can be represented as: LGJ-300/50 GB1179-83

　　[Main purpose]: Generally, for high-voltage transmission lines, due to the limited path of the line and the inability to install 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 example, for 500KV transmission lines, China mostly adopts the method of hanging four wires, which is called the same tower parallel installation. This is the main reason why some poles are used for both "L J" and "LGJ".
