What is a shielded cable

According to professionals, cable prices often vary greatly due to differences in commonly used raw materials during processing. The key raw materials for manufacturing electric cables are electrolytic nickel, insulating layer materials, and insulating materials. In the raw material sales market, a ton of electrolytic nickel is around 50000 yuan, while a ton of purchased copper can only be around 40000 yuan; The price of famous and high-quality insulating materials and insulating materials is between 8000 yuan and 10000 yuan per ton, while the price of defective products is only 4000 yuan to 5000 yuan per ton, making the price difference even wider. In addition, insufficient length and insufficient glue content in conductors and insulators are key reasons for price differences. The length of each row is 100 meters for high-quality products, while 90 meters for scrap products; The glue content of conductors and insulators is 35% to 40% for high-quality products, while only 15% for defective products. According to the comparison, customers can see that the difference in the market price of finished cable is caused by the existence of insider information on materials Rubber sheathed cable for mining

According to industry insiders, the reason why the price difference of household electric wires is immeasurable is due to differences in raw and auxiliary materials used in the production process. The primary raw and auxiliary materials for producing and processing household electric wires are electrolytic nickel, thermal conductive materials, and PVC particles. In the raw and auxiliary material market, electrolytic nickel is less than 50000 pieces per ton, while the recycled copper is only less than 40000 pieces per ton; The price of high-quality products such as thermal conductive materials and PVC particles ranges from 9000 yuan to 12000 yuan per ton, while the price of substandard products only costs 5000 yuan to 6000 yuan per ton, making the price difference even more significant. On the other hand, the lack of overall length and the low glue content of the conductive body are also crucial root causes of the price gap. The total length of each dial is 150 meters, while the environmental protection grade is only over 95 meters for inferior products; The rubber content of the conductive body accounts for 45% to 50% of the environmental protection grade, while the defective products only account for 16%. By comparison, buyers can see that the difference in the sales price of household electric wires is due to the hidden rules in the material Overhead insulated cable

According to authoritative sources, the reason why cables can be quoted differently is due to the different raw materials used in the production and manufacturing process. The specific raw materials for producing cables are electrolytic nickel, thermal insulation materials, and cable materials. In the raw material market, one ton of Yangshang electrolytic nickel is around 50000 yuan, while one ton of second-hand recovered copper is only around 40000 yuan; The quotation for high-quality products of thermal insulation materials and cable materials is between 6000 yuan and 20000 yuan per ton, while the quotation for scrap products is only between 6000 yuan and 4000 yuan per ton, with a significant price difference. The lack of size and the low glue content of the insulation are the main reasons for the different quotations. The size of each row of wires is 200 meters for qualified products, while only 80 meters for defective products; The qualified products with glue content in insulating materials account for 37%~45%, while only 14% of the residual products. With the help of comparison, customers can see that the common differences in the retail prices of machinery, equipment, and cables are caused by the widespread existence of black screens on the quality of materials.
