The quality of the identification standard power cord What

 The power cord is the task of the people's life and daily necessities, especially home improvement, office and production lighting, power line quality and safety seriously. Many fire attack because of the aging power line, equipment unreasonable, perhaps the use of low-quality mass power lines are formed, and therefore, consumers in the purchase of the wire must polish his eyes, careful to identify and take preventive measures. The country requires the use of the new housing, office and production illumination insulated copper wire, but the same copper wire, copper wire have poor, its copper core choices are recycled copper, recycled copper containing many impurities, and some low-quality copper wire conducting function even as wire, easy to stimulate electrical accidents. Currently, multi-wire brands on the market, the price confusion, consumers choose is very difficult. Alone home decoration, office and production lighting commonly used 2.5 mm2 and 4 mm2 copper wire two kinds of prices, the same size of a roll of the power cord, manufacturers differences, the price difference of 10% - 20% Even more, as the quality is good or bad, whether the standard length, the consumer is more difficult to determine. The reason why the price is a big difference between the power line, because the production process, differences in raw materials used in the formation. The main raw materials in producing power cord is copper, insulation materials and insulation sheath material. Currently, on the market at 49,000 yuan per ton copper Excellency, and the recycling of scrap copper as long as 33,000 yuan per ton, sir; high product prices and raw materials of ecological insulation sheathing material --10 000 yuan per ton, 9,000 yuan, while the Perhaps the regeneration of defective products price only 5000 yuan 6000 yuan per ton, the difference is huge. In addition, the length of the lack of an insulator gel content is not enough, is also the main reason for the formation of the price difference. Wire length of each volume, superior product (GB) is 100 m ± 0.5 m is at least 99.5 m / roll, and rejects as long as 95 meters, and is known as the national standard, and some even as long as 80 meters Excellency. After contrast, the consumer is not difficult to see that there is a difference of finished power line sales price is the material gap. Plug the power cord when using matters Unplug the power cord, plug the power cord grip is removed, not just pull the wire, causing internal copper wire fracture. Plug the power cord can not be pressed against the bottom of furniture or heavy objects to avoid damaging dangerous. 1, the internal copper wire power cord breaking part is called a half break, half broken when a current flows because the circuit suddenly narrowed, resulting in overload and generate heat. 2, the use of v, should be careful not to bind; the power cord after the bundle is difficult to distribute the heat, so the temperature rises and the plastic melt, causing a short circuit fire copper. 3, plug the power cord to avoid placing stove top, due to fire high temperature will melt the plastic, copper short circuit caused the fire. 4, plug the power cord should be under the allowable load capacity usage, and to extend the line, there are multi-socket connection should use products with overload protection device leakage protection device or before. 5, using the old, damaged power cord can cause a short circuit, leakage or other dangerous induction should be updated immediately. 6, the use of plug the power cord is hot or odors? This is overload, should immediately stop using the high power electrical notify qualified electrician check. 7, confirm whether simple algorithm overload plug the power cord: Plug the power cord brought electrical power and / or power supply voltage, the result is the current estimate, it will be compared with the socket rated capacity should be less than the rated capacity of the socket.
