Power cords are everyday necessities in people's daily lives and tasks, especially in home decoration, office, and production lighting. The quality of power cords is very important. Many fire alarms are caused by aging power cords, unreasonable equipment, or low-quality power cords. Therefore, consumers must be vigilant when purchasing power cords, carefully identify them, and take preventive measures.
National requirements mandate the use of copper-core insulated wires in newly constructed houses, offices, and production lighting; however, even copper wires can be of inferior quality. Copper cores are made from recycled copper and contain many impurities; some low-quality copper wires have conductivity even lower than iron wire and easily cause local electrical accidents. Currently, there are many wire brands and prices on the market, making it difficult for consumers to choose. For 2.5-square-millimeter and 4-square-millimeter copper-core wires commonly used in home decoration, office, and production lighting, the price difference between power cords of the same specification can range from 10% to 20% due to different manufacturers. Consumers find it even more difficult to determine the differences in quality and length.
The reason for the huge price difference in power cords lies in the difference in raw materials during production. The main raw materials for power cord production are electrolytic copper, insulating materials, and sheathing materials. Currently, the market price of electrolytic copper is approximately 49,000 yuan per ton, while the price of recycled scrap copper is only 33,000 yuan per ton. The price of the product is 9,000-10,000 yuan per ton, and the price of scrap is only 5,000-6,000 yuan per ton, with a significant price difference. In addition, the lack of length and insufficient glue content in the insulator are also important reasons for the price difference. High-quality products (national standard) have a minimum length of 99.5 meters per roll, while inferior products are usually 95 meters long and are labeled as meeting national standards, some are even as short as 80 meters. In comparison, it is not difficult for consumers to see that the difference in the sales price of finished power cords is due to the difference in materials.
How to use a plug power cord? When unplugging a plug power cord, you should hold the plug to pull it out. Do not just pull the wire, as this may cause the copper wire inside the cord to break. The plug power cord should not be pressed under furniture or heavy objects to avoid the risk of damage. 1. The copper wire part inside the plug power cord is called a half-broken wire. When current passes through the half-broken wire, the circuit suddenly narrows, causing overload and generating high heat. 2. Be careful not to bundle it when using; due to the bundling of the power cord, heat is difficult to dissipate, the temperature rises, the plastic melts, causing the copper wire to short circuit and cause a fire. 3. Avoid placing the power cord on the stove, as the high temperature of the stove will cause the plastic and sheathing to melt, causing the copper wire to short circuit and cause a fire. 4. When using the power cord, it should be used under the allowed load capacity; extension cords should be connected to multi-socket outlets; products should have leakage protection or overload protection devices. 5. Do not use old and damaged power cords, as this can lead to dangers such as short circuits, leakage, or induced electricity; they should be replaced immediately. 6. Does the plug power cord get hot or have a peculiar smell during use? This is an overload phenomenon. High-power electrical appliances should be stopped immediately, and a professional electrician should be notified for inspection. 7. A simple algorithm to confirm whether the plug power cord is overloaded: compare the sum of the electric power/power of the plug power cord with the rated current of the socket; the result should be less than the rated capacity of the socket.
