CUSTOMER CASE
At present, the quality of power cords on the market varies from good to bad, and consumers need to choose carefully. Sometimes I even took pains to choose, but the quality of the power cord products I bought was still poor. So what should consumers do to prevent buying low-quality power cords?
The best one: weighing
Foot square copper is a relatively precious metal material. If the manufacturer reduces the copper diameter by a little bit, the production cost of the enterprise can be reduced. When buying a power cord, consumers can use a micrometer to measure the diameter of the copper wire. If there is no micrometer, you can weigh the power cord. Take the security power cord to the scale and weigh it. At the same time, this data can be compared with the data given by the manufacturer, and it can also be compared with other power cord products. In this way, we can know whether the manufacturer is cutting corners.
Great trick two: look at the accessories
accessories can ensure the roundness of the power cord, some fillers will be added to the multi-core power cord, and the sheath is also quite thick. If the power cord in the hand is not round, it means that there is less filler and the sheath is thinner.
Three great tricks: look at the situation of copper wire bundles
The copper wire of the power cord is not a single piece, but is composed of several wires to improve its tensile strength and roundness. Bundle wire has great benefits for the use of copper wire. However, although the current enterprises will increase the use of copper wire, they will default to the steps of wire binding. Just break the power cord and check the arrangement of the copper wires to see whether the power cord is good. As long as they are twisted together regularly, you can buy them with confidence, otherwise you don't need to buy them.
The above are more practical identification methods taught by experts, which can help people choose a better power cord.
