Characteristics of steel cored aluminum stranded wire:
Steel core aluminum stranded wire follows the standard. Steel core 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.
Characteristics and advantages of steel core aluminum stranded wire. Steel core aluminum stranded wire is a reinforced conductor consisting of single or multiple layers of aluminum strands twisted outside of galvanized steel core wire. Mainly used in the power and transmission line industries. Steel cored aluminum stranded wire is made by twisting aluminum wire and steel wire, and is suitable for overhead transmission lines. 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. The models of steel cored aluminum stranded wire are divided into JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A, where G1A or G1B refers to ordinary strength steel wire. G2A or G2B refers to high-strength steel wire. G3A refers to ultra-high strength steel wire. Advantages of steel core aluminum stranded wire: Steel core 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. 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.

4.1 Galvanized steel wire in steel core aluminum stranded wire shall comply with the provisions of GB3428-82 "Galvanized Steel Wire for Steel Core Aluminum Stranded Wire" and Appendix D of GB1179-83

Packaging and transportation:
Steel cored aluminum stranded wire should be delivered in reels, with the distance between the outermost layer and the edge of the cable reel side panel not less than 30mm, and properly packaged. The two twisted wires connected together during packaging should have at least half of the aluminum wire cut at the connection point, and the two sides of the connection point should be firmly tied. The cable reel shall comply with the provisions of GB4005-83 "Delivery reels for wires and cables". Short stranded wires are allowed to be delivered in loops, and each loop should be tied at least three times and properly packaged. The product should be inspected and qualified by the manufacturer before leaving the factory, and each product leaving the factory should be accompanied by a quality inspection certificate.
Steel cored aluminum stranded wires are arranged in a criss crossing manner on transportation vehicles such as vehicles and ships. The cable reels must be placed steadily, and both sides must be firmly fixed to the transportation vehicle with steel wire ropes. The bottom of the cable reels should be plugged with triangular wedges to prevent them from shaking, colliding, or tipping over during transportation. When transporting large cable reels, attention should be paid to selecting road transportation equipment. If using heavy-duty trucks for transportation, the height of the truck should comply with the height restrictions of bridges, culverts, etc. on the traffic road. If the limit is exceeded, a dedicated trailer can be used to reduce the transportation height. When the cable reel rolls on the ground, it must be rolled in the direction indicated by the arrow on the side of the cable reel. Rolling in the opposite direction will cause the cable to unwind and loosen. For cables without protective plates, the two side plates must protrude more than 10cm from the outer layer of the cable when rolling. During rolling, hard objects should be prevented from pressing under the cable reel to avoid damaging the cable. When rolling the cable reel, it should be controlled within a small distance range, and special equipment such as forklifts or cranes should be used for long-distance movement.
