　　 The main products of Dazheng Electric Wire Co., Ltd. include steel cored aluminum stranded wire, steel stranded wire, aluminum stranded wire, aluminum clad steel stranded wire, OPGW optical cable, ADSS optical cable, special optical cable, high and low voltage power cable, control cable, high and low voltage overhead insulated wire, cross-linked cable, aluminum alloy cable, communication cable, shielded cable, high temperature resistant cable, special cable, fittings, etc.

　　The main applications of steel cored aluminum stranded wire are:

　　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.

　　In our family life, the use of steel cored aluminum stranded wire is constantly expanding. Steel cored aluminum stranded wire has very strong corrosion resistance. It should be noted that the main application of steel stranded wire is in large-scale projects such as bridge construction, scenic area construction, energy construction, etc. It is worth noting that steel cored aluminum stranded wire has a high load-bearing capacity. Taking the steel strand used in tourist attractions as an example, if the load-bearing capacity of the steel strand is relatively small, it cannot be used in the scenic area. The cable car itself has a certain weight, and several tourists also have a certain weight themselves. In this way, the load-bearing capacity of the steel strand must be much greater than everyone's own weight.

　　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. In the modern era of advanced science and technology, many modern industrial facilities have appeared in our world and exist in our lives. Steel cored aluminum stranded wire also plays an important role as the main force in electricity. 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.

　　Construction process requirements for steel core aluminum stranded wire:

　　1. The DC resistance shall not exceed the provisions of GB1179 standard;

　　2. The product should comply with the calculated tensile strength specified in the standard;

　　3. The product should comply with the process requirements such as pitch and twist direction specified in GB1179;

　　4. The product should meet the delivery length specified in the standard, but with the consent of the purchaser, it is allowed to be delivered in any length of stranded wire;

　　5. The surface of the product should be round and smooth, without scratches, oil stains, snake shapes, exposed inner layer sticking molds, and other defects;

　　6. The products should be arranged neatly, packaged with moisture-proof and waterproof materials, and attached with a certificate of conformity.

　　 The advantage of steel cored aluminum stranded wire is that it has a simple composition, but it has powerful functions and can be used on high voltage electrical frames to ensure the normal operation of voltage output. Some places have unique geographical conditions, such as stranded wires on long rivers and high mountains that can maintain a large span without breaking. The emergence of stranded wires reduces the difficulty of installing high-voltage electrical racks. If there is strong wind, there is no need to worry about them being pulled, and they can be used for a longer time in harsh environments, ensuring that maintenance and replacement are not required for a long time. The production cost of twisted wire is relatively low, which can save a significant portion of installation costs. Another important advantage is that it can carry large voltage and current loads. If high-intensity current output is required, the stranded wires can be concentrated together to increase the propagation force and speed, helping to output electricity in situations with high electricity consumption.

　　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.
