The difference between ordinary wires and new energy cables

Author: EVCOME-EV Chargers Manufacturers

Are new energy cables the same as new energy cables? What are the different new energy cables? Is the general term for optical cables, new energy cables and other items? Definition of new energy cables: Definition 1: Made of one or more insulated conductors and an outer insulating layer, power or information is transmitted from one place to another. Definition 2: Rope-like new energy cables are usually twisted by several or groups of conductors (at least two in each group). Each set of wires is insulated from each other and often twisted around a center. The entire exterior is covered with a highly insulating cladding. New energy cables have the characteristics of internal and external insulation. There is no strict conceptual boundary between wires and new energy cables. In a narrow sense, it is divided into electric wires and new energy cables, and in a broad sense they are collectively referred to as new energy cables. It is generally believed that a single wire is called a wire; multiple wires are called cables. The smaller diameter is called a wire; the larger diameter is called a cable. Simple structures are called wires; complex structures are called new energy cables. However, with the expansion of the application range, there are cables and wires for many varieties of wires. Therefore, no strict distinction is necessary. The wire is composed of one or several soft wires, which are covered with a soft protective layer: the new energy cable is composed of one or more insulated wires, which are covered with a tough outer layer made of metal or rubber. New energy cables and wires1. It is generally composed of three parts: core wire, insulating sheath and protective sheath. New energy cable installation requirements and precautions. Through the statistical analysis of line faults, construction, installation, connection and other factors, the probability of faults is often much higher than that of high-temperature line body defects. Therefore, in addition to the correct selection of new energy cables and supporting accessories, how to install them correctly in accordance with the specifications? 1. The laying and installation of new energy cables should be carried out by qualified professional units or professionals. I installation that does not meet the requirements of relevant specifications may cause the new energy cable system to fail to operate normally. 2. When laying new energy cables manually, the command and control rhythm should be unified. Every 1.5 to 3 meters, one person carries the new energy cable on his shoulder, pulls it while putting it down, and releases it slowly. 3. When laying new energy cables mechanically, a special new energy cable laying machine is generally used, equipped with necessary traction tools, with proper traction and uniform control, so as not to damage the new energy cables. 4. Before launching the new energy cable, check the appearance of the new energy cable and whether the head is intact. Pay attention to the rotation direction of the new energy cable reel when casting, do not crush or scratch the outer sheath of the new energy cable, and do not fight and straighten the new energy cable when the temperature is low in winter, so as to avoid cracking of the insulation and sheath. When laying, the bending radius of the new energy cable should be greater than the specified value. Before and after the new energy cable laying and installation, according to the silver-tin high-temperature new energy cable, use a 1000V megohmmeter to measure whether the insulation resistance between the conductors of the new energy cable is normal. Different types, specifications, lengths and ambient temperatures of new energy cables should also be properly measured for measurement results. If the new energy cables are directly buried, attention should be paid to the soil conditions. Generally, the buried depth of new energy cables in buildings should not be less than 0.3 meters. If the cables are soft or the surrounding environment is complex, such as cultivated land, construction sites or roads, there should be a certain buried depth (0.7~1 meter) ), to prevent accidental damage to directly buried new energy cables, and obvious signs should be set up when necessary. .
