With the continuous development of society, our lives are inseparable from electricity, and the prerequisite for using various electrical and electronic products is the power cord. Every household needs a large number of power cords to build a current network to supply power to all devices. Without power cords, our daily lives will be a mess. It is precisely because of its importance, so when buying, we must pay attention to standards.
What standard should be selected for rubber wire and cable? First of all, formal. Try to buy from a regular manufacturer, and the selected products must have national certification marks and trademarks, specifications, factory numbers, voltages, etc. Secondly, packaging. Conventional manufacturers use PVC transparent film to wrap the wires once during the wire packaging process, and then use a snake-shaped belt to wrap the wires again to ensure that the product is not easily damaged during transportation. weight. The weight of a high-quality power box is within the specified range. Generally speaking, the weight of a two-core rubber sheathed cord with a cross-sectional area of 0.75mm2 is 200 meters, which is between 12.3kg and 12.8kg.
In addition to these standards, when purchasing a power cord, you can cut a part of the insulation to see if the core wire is in the middle of the insulation. Power cords with eccentric cores may cause weakness to prevent easy breakdown.
Rubber wire and cable is a certificate issued to the manufacturer after the product has passed the test of the EU VDE certification body.
In layman's terms, it refers to the square number. This is the most common phenomenon in the market. For example, the online mark is 0.75 square, and the actual measured value is 0.673 square. Such a square number is unqualified. This requires asking the supplier for the copper conductor structure. The conductor structure of 0.75 square is 24/0.2, that is, 24 copper wires with a diameter of 0.2. Each square wire has its conductor structure, so you must understand it when buying. To avoid unnecessary troubles caused by insufficient copper, common symptoms include shortened service life, heating of wires, and short circuits caused by resistance.
