　　 Manufacturer sells JL/G1A-300/50 Beijing steel cored aluminum stranded wire manufacturer

　　Application of steel cored aluminum stranded wire;

　　The specification of steel cored aluminum stranded wire is 10/2~1440/100, and the product complies with the standard GB/T1179-2017.

　　 Steel cored aluminum stranded wire, English name: aluminum conductor steel reinforced，ACSR。 It is a reinforced conductor with single or multiple layers of aluminum stranded wires twisted outside a galvanized steel core wire. Mainly used in the power and transmission line industries.

　　 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 in special geographical conditions such as crossing rivers and valleys. It has good 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.

　　 Its interior is made of steel core, and the exterior is wrapped around the steel core by twisting aluminum wire; Steel core mainly plays a role in increasing strength, while aluminum stranded wire mainly plays a role in transmitting electrical energy.

　　Steel cored aluminum stranded wire has the characteristics of a very simple structure, easy installation, convenient maintenance, low line cost, large transmission capacity, and is also conducive to laying across special geographical conditions such as rivers and valleys. 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 of various voltage levels.

　　If necessary, the resistivity of the single wire should be measured on the selected single wire from the stranded wire. The sample should be manually straightened and measured according to the method specified in GB/T 3048.2-2007. The test results should meet the requirements of the corresponding single wire standard. Except for galvanized steel stranded wire, resistivity measurement is generally not required for all galvanized steel wires.

　　Surface condition

　　The surface of the stranded wire should meet the requirements of 5.3. 6.6.7 Pitch to diameter ratio and twist direction

　　The pitch to diameter ratio of each layer of twisted wire should be the ratio of the measured pitch to the outer diameter of that layer.

　　The measured values should meet the requirements of 5.4. In addition, attention should be paid to the twisting direction of each layer, which should also comply with the requirements of 5.4.

　　packaging

　　During normal loading, unloading, transportation, and storage, wires should be properly packaged to prevent damage.

　　The wires should be delivered in reels, with the distance between the outermost layer and the edge of the cable reel side panel not less than 30 mm, and properly packaged. The two wires connected together should have at least half of the single wire cut at a distance of not less than 15 cm from the connection point, and the fracture should be tightly tied.

　　The delivery tray shall comply with the provisions of JB/T 8137-2013 (all parts), or may be agreed upon by the supply and demand parties through mutual agreement. Short section wires are allowed to be delivered in loops, and each loop should be tied at least three times and properly packaged.

　　Each coil or circle of wire should be labeled with:

　　Each coil or turn of wire should be labeled with the following information:

　　Manufacturer name, manufacturer serial number (if any); Wire model, nominal cross-section, and number of single wires;

　　Shipping, rotation direction, or line marking; The marking that the spool cannot be placed flat during transportation; The length, gross weight, and net weight of each wire from outside to inside, in kilograms;
