Description :

　　Steel cored aluminum stranded wire manufacturer Zhengfan brand JL/G1A-240/30

　　Application and characteristics of steel cored aluminum stranded wire；

　　1. Main applications

　　For high-voltage transmission lines, due to the limited route of the line and the inability to install multiple lines on the same route, people have come up with the method of using a single path, a set of iron towers, and hanging multiple wires, that is, one line is equivalent to installing multiple lines. For 500KV transmission lines, most countries use the method of hanging four wires, which is called the same tower parallel installation.

　　Characteristics of steel cored aluminum stranded wire:

　　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 optimal laying across mountains, rivers, and valleys with special geographical conditions. It has good conductivity and sufficient mechanical strength, high tensile strength, and can amplify tower distance. Therefore, it is widely used in overhead transmission and distribution lines.

　　2. Execution labeling and representation methods for steel cored aluminum stranded wire

　　The standards we have mainly implemented include GB1179-74, GB1179-83, GB 1179-1999, and the current GB 1179-2008. Now, the representation methods for different standards are introduced as follows: the representation method in GB 1179-74 standard: code - nominal section of aluminum stranded wire standard number such as LGJ-400 GB 1179-74. Commonly used models and meanings: LGJ - steel core aluminum stranded wire LGJQ - light steel core aluminum stranded wire LGJJ - reinforced steel core aluminum stranded wire model, where 240 represents a nominal section of 240mm2 for steel core aluminum stranded wire. The representation method in GB 1179-83 standard: code - nominal section of aluminum stranded wire/nominal section of steel stranded wire standard number, such as LGJ-240/thirty The meaning represented in GB 1179-83 model: LGJ - Steel cored Aluminum Stranded Wire LGJF - Corrosion resistant Steel cored Aluminum Stranded Wire model 240 represents the nominal cross-section of the aluminum stranded wire in the steel cored aluminum stranded wire is 240mm2; 30 indicates that the nominal cross-section of the steel strand in the steel cored aluminum wire is 30mm2. The specific parameters of the old models of steel cored aluminum stranded wire can be found in the "Main Technical Parameters of the Old Code for Steel cored Aluminum Stranded Wire (GB1179-74)" and "Main Technical Parameters of the Old Code for Steel cored Aluminum Stranded Wire (GB1179-83)".

　　The representation methods in GB 1179-1999 and GB 1179-2008 standards:

　　Code - nominal section of aluminum stranded wire/nominal section of steel stranded wire - number of aluminum stranded wire structures/number of steel stranded wire structures. Standard number: JL/G1A-400/50-54/7 GB 1179-2008. Common models and meanings: JL/G1A, JL/G1B, JL/G2A, JL/G2B, JL/G2A - steel core aluminum stranded wire JL/G1AF, JL/G2AF - anti-corrosion steel core aluminum stranded wire G1A, G1B - ordinary strength steel wire (single wire metal resistivity is 191.57n Ω· m, corresponding to 9% IACS) G2A, G2B - high-strength steel wire (single wire metal resistivity is 191.57n Ω· m, corresponding to 9% IACS) 9% IACS) G3A - Ultra high strength steel wire (single wire metal has a resistivity of 191.57n Ω· m, corresponding to 9% IACS) model, where 240 represents the nominal cross-section of the aluminum stranded wire in the steel core aluminum stranded wire, which is 240mm2; 30 represents the nominal cross-sectional area of the steel strand in the steel core aluminum stranded wire as 30mm2, 24 represents the number of aluminum strands in the steel core aluminum stranded wire as 24, and 7 represents the number of steel strands in the steel core aluminum stranded wire as 7.
