Supplier's quotation for JL/G1A-95/15 steel cored aluminum stranded wire power overhead transmission

Description :

　　 JL/G1A-95/15-26/7 model steel cored aluminum stranded wire power overhead transmission transformer

　　Introduction to the use of steel cored aluminum stranded wire:

　　 JL/G1A-95/15 steel cored aluminum stranded wire is made by combining steel and aluminum. Our company specializes in the production of steel stranded wire cores, from the aluminum wires of aluminum rods to the twisting into steel core aluminum stranded wires, all of which are manufactured in-house.

　　95/15 wire, twisted with 7 1.67 steel wires to form a right-handed core, passed through a frame twisting machine, twisted with steel wire cores+10+16 aluminum wires to form a right left right twisted product.

　　The total cross-sectional area is 110 square meters, including 15 square meters of steel strands, which mainly serve to enhance the tension of the wires. The cross-sectional area of the aluminum core is 95 square meters. As the main conductor.

　　 Advantages of Steel Core Aluminum Twist

　　Steel cored aluminum stranded wire; It refers to a reinforced conductor in which a single or multiple layers of aluminum stranded wire are twisted outside a galvanized steel core wire. Mainly used in the power and transmission line industries.

　　aluminum conductor steel reinforced (ACSR)

　　Stranded single-layer or multi-layer aluminum wire on galvanized steel core wire

　　Core 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;

　　The models of steel cored aluminum stranded wire are divided into: JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A

　　Among them, 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.

　　Model difference: Taking JL/G1A-95/15 steel cored aluminum stranded wire as an example.

　　Represented as JL/G1A-95/15 in the national standard (GB/T1179-2017);

　　In the national standard (GB/T1179-1983), it is represented by LGJ-95/15.

　　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.

　　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.
