　　Advantages of steel cored aluminum stranded wire:

　　 The single-layer or multi-layer process stranded wire of steel core aluminum stranded wire is a reinforced conductor outside the galvanized steel core wire, which plays an important role in the power and transmission line industry. Below is a brief introduction to the advantages and applications of steel core aluminum stranded wire.

　　 Steel cored aluminum stranded wire is made by twisting aluminum wire and steel wire, and is suitable for overhead transmission lines. Its interior is a steel "core", and the exterior is wrapped around the steel core with aluminum wire twisted together. The steel core mainly increases strength, while the aluminum wire mainly transmits electrical energy.

　　 Because there are many output directions for high-voltage circuits, but the number of lines is still limited, technicians have designed high-voltage electrical racks to concentrate the lines on this rack and output them in the specified direction. This will increase the number of lines and ensure safer power output work, as well as more centralized management. An important material used in high-voltage electrical racks is steel cored aluminum stranded wire. This type of wire is mainly composed of two metal materials, one is steel and the other is aluminum. Based on steel, a main core is made inside, and then the aluminum wire is wrapped around the outside according to certain rules. The role of the steel core is to increase the overall strength and hardness, ensuring that the stranded wire can be used in high-pressure environments. Aluminum wire has good conductivity and can ensure the rapid propagation of current.

　　 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 precautions:

　　 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.
