How To Identify The Pros And Cons When Buying Booster Cables
How to identify the pros and cons when buying booster cables
The state has expressly used copper conductors in new dwellings. But the same is copper booster cable, there are inferior copper conductor, its copper core selection of recycled copper, containing many impurities, some inferior copper conductor conductive performance or even less than booster cable, very easy to cause electrical accidents. At present, the market on a variety of booster cable, specifications, price disorder, consumers are very difficult to choose. Single on the home decoration commonly used in 2.5 square mm and 4 square mm two kinds of copper cored booster cable price, the same specification of a line, because the manufacturer different, the price can be $number. As for quality, whether the length of standards, consumers are difficult to determine.
According to the industry sources: the price difference between the booster cable is huge, because the production process of raw materials used in the same frequency cable caused. The main raw materials for the production of electric booster cables are electrolytic copper, insulating material and sheath material. At present, the raw materials market electrolytic copper per ton in about 50,000 yuan, and recycled copper per ton only about 40,000 yuan, insulating materials and sheath material price per ton in 8000 yuan ~10000 yuan, and defective goods price per ton just 4000 yuan ~5000 yuan, the difference is more disparity. In addition, the length is insufficient, the insulator contains not enough glue quantity, also cause the price difference important reason. The length of each line, the excellent product is 100 meters, and defective only about 90 meters, the insulation volume of high-grade products accounted for 35% ~, and defective only 15%.
