　　 LGJ240/30 price standard 240 steel core aluminum stranded wire manufacturer

　　 The products of Dazheng Electric Wire Co., Ltd., including copper-clad aluminum wire and cable, steel core aluminum stranded wire price list, Dazheng brand steel core aluminum stranded wire, JKLGYJ overhead insulated cable, JKLYJ-10kV overhead insulated wire, are widely used in many fields such as power, wind power, photovoltaics, mining, petroleum, railway, construction, etc., and are at the same industry level in more than 30 provinces, municipalities and autonomous regions across the country.

　　 Characteristics of steel cored aluminum stranded wire:

　　 The production of steel core aluminum stranded wire must comply with the provisions of GB/T5224-2003, and should have good straightening performance. The appearance requirements are that the sheath surface should be smooth, without depressions, visible steel strand contours, cracks, pores, obvious wrinkles, and mechanical damage. Only high-quality steel core aluminum stranded wire can win the favor of users.

　　 Steel cored aluminum stranded wire refers to a reinforced conductor in which a single or multiple layers of aluminum strands are stranded outside a galvanized steel core wire. Mainly used in the power and transmission line industries. Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy.

　　 The inner part of the steel core aluminum stranded wire is a steel core, and the outer part 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.

　　 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-240/30 steel core aluminum stranded wire as an example.Represented as JL/G1A-240/30 in the national standard (GB/T1179-2008);

　　In the national standard (GB/T1179-1983), it is represented by LGJ-240/30.

　　 The steel cored aluminum stranded wire (JL/G1A and LGJ) is wrapped around the steel wire by twisting multiple strands of aluminum single wire externally; Steel core mainly serves to increase tensile strength, while aluminum wire mainly serves to transmit electrical energy.

　　Among them, G1A and G1B refer to ordinary strength steel wires; G2A and G2B refer to high-strength steel wires; G3A refers to ultra-high strength steel wire.

　　 Steel cored aluminum stranded wire is mainly used in medium and high voltage transmission lines. Due to the limited path of the line and the inability to install multiple lines on one road, people have come up with the idea of using a single path, where multiple steel cored aluminum stranded wires are hung on one tower.

　　 That is, one line is equivalent to setting up multiple lines; For 220KV, 500KV, 800KV, and 1000KV lines, China adopts the method of hanging four or six wires (four wire, six wire method), which is called the same tower and parallel installation.

　　Advantages: Steel cored aluminum stranded wire has a simple structure, easy installation and maintenance, low line cost, large transmission capacity, and long distance, which is also conducive to the installation across special geographical conditions such as rivers and valleys.

　　It has good electrical conductivity, sufficient mechanical strength, tensile strength, and the ability to amplify tower distance. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.

　　 Specification of steel cored aluminum stranded wire: 10/2~1440/100, in accordance with standard GB/T1179-2017.

　　Transportation and packaging of steel cored aluminum stranded wire:

　　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.
