Do you know how to purchase qualified cable products?
Home life cannot do without wires. Today, taking BV wires as an example, which are commonly used in daily life, we will teach you how to purchase qualified wires.
1. Check the certification mark of the BV wires, and products that have obtained mandatory certification will have a certification mark affixed in a prominent position, namely the "CCC mark".
2. According to the BV wire inspection report, as a product that affects personal and property safety, wires and cables have always been listed as a key focus of supervision and inspection. Manufacturers are subject to periodic inspections by supervisory departments.
3. Check the insulation and sheath of the BV wire. The thickness of insulation and sheath should be uniform and without deviation, and there should be obvious tension and elongation in the feel. At the same time, the insulation and sheath surfaces should be continuously printed with the manufacturer's name and product model.
4.Observe the smoothness and color of the thread. Copper conductors for wires and cables are annealed copper wires with or without metal plating, while aluminum conductors are aluminum or aluminum alloy wires with a smooth surface. Copper conductors are light purple, while aluminum conductors are silver white. Otherwise, other impurities may be added to the conductors, leading to a decrease in conductivity.
