This article focuses on the 4-core aluminum cables of YAKXS and YAKXS-Zo models, which have significant application value in the field of power transmission. Their insulation layer is made of cross-linked polyethylene (XLPE), which has excellent electrical insulation performance, temperature resistance and aging resistance. It can work stably in the temperature range of -40℃ to 90℃, effectively ensuring the safety and reliability of power transmission. The sheath is made of polyvinyl chloride (PVC), which not only has good mechanical strength, can resist external mechanical damages such as collision and extrusion, but also has certain moisture-proof and anti-corrosion capabilities, prolonging the service life of the cable.​ This series of cables has a wide range of specifications, including 25mm², 50mm², 95mm² and 70mm², which can meet the power transmission needs of different power equipment and scenarios. The 25mm² specification is suitable for low-power electricity scenarios such as small electrical appliances and home lighting; the 50mm² and 70mm² specifications are often used in medium-sized industrial equipment, commercial building power distribution systems, etc.; the 95mm² specification, due to its large current-carrying capacity, is applicable to medium and high-power scenarios such as large industrial production lines and main power distribution lines of large buildings.​ The prices of cables with different specifications vary, affected by many factors. In terms of raw materials, the fluctuation of aluminum prices directly affects the cost of cables, and the price changes of XLPE and PVC will also indirectly affect the final price. The market supply and demand relationship is also crucial. When the market demand is strong and the supply is insufficient, the price tends to rise, and vice versa, it may fall. The complexity of the production process also affects the price. The larger the specification of the cable, the higher the requirements for the process in the production process, the corresponding increase in cost, and the price will also increase.​ Taking the data of common procurement platforms as an example, the price of 25mm² cables generally fluctuates in the range of ​ 0.25to 3.55 per meter; the price of 50mm² cables is about ​ 0.35to 6.90 per meter; the price range of 70mm² cables is ​ 0.44to 5.00 per meter; the price of 95mm² cables is about ​ 0.32to 6.00 per meter.​ These prices are not fixed. For bulk purchases, suppliers usually offer certain discounts, and the larger the purchase quantity, the higher the discount may be. Prices also fluctuate in different purchase periods. For example, during the peak season of power construction, when demand increases, prices may rise; while in the off-season, prices may be reduced to stimulate sales.​ For accurate quotations, it is recommended to contact relevant suppliers and clarify detailed information such as purchase quantity, delivery location and special requirements, so that suppliers can formulate a price plan more in line with the needs according to the actual situation. At the same time, you can also know whether additional services such as transportation and installation are included to ensure the transparency and controllability of procurement costs.
