A multi-core cable is a cable with more than one insulating core. When there is alternating current or alternating magnetic field in the conductor, the current inside the conductor is asymmetrical, and the current is concentrated on the conductor skin. In other words, the current is focused on the analysis of the conductor surface. The closer to the conductor surface, the greater the current intensity, and the smaller the real current inside the conductor. Therefore, the resistance of the conductor increases and the output power also increases. This condition is known as skin chemotaxis. When the evcome new energy cable single-core cable is exposed to alternating current or alternating magnetic fields, the skin effect is remarkable, and the route consumption increases. Compared with the skin effect of a single-core cable, a multi-core cable consisting of several insulating cores reduces the skin effect of the cable and reduces damage to the distribution line. Taking 12-core cables as an example, the structure of multi-core cables is divided into layered cables and split cables. Layered into cables: Most cables have copper cores tightly wrapped around the axis in multiple layers, toasted with extruded jackets. When the cable is bent and compressed, the inner diameter is stressed, the diameter is pulled, the inner diameter is stressed, and the frequency of the bending cycle system is greatly reduced. Such cables are characterized by relatively low manufacturing costs. Bundling into cables: Cable copper core cables are first independently twisted to form cables, and copper core cables are tightly wound around a core strand made of stretched material to form cables. Due to the beam splitting process, inside the cable, the copper core cable changes the diameter and diameter of the bent cable many times, and the tension and working pressure around the relatively highly stretched shaft balance each other, making the internal structure of the cable stable and reliable. Therefore, the locking cable can also be maintained for a long time under the greatest stress. General comparison of multicore cables and cable drag chain cables. evcome new energy cables multi-core cables and flexible cables are generally used for fixed installation. In the installation process, only the force and bending radius of the cable should be considered, and the layered cable can meet the requirements. Cable drag chain cables are mainly used for movement and should be kept under stress for a long time. The cable drag chain cable stipulates the frequency and service life of the circulation system. Layered cables and split cables are used, but the service life of the split cable drag chain cables is significantly higher than that of layered cables. Imported high-end cable drag chain cables mostly use split bundles. cable. Middle and low-end cables are more common in layered cable drag chain cables. Due to its high quality and low price, this kind of cable drag chain cable also has a certain market demand. In a good natural environment, the cable can be used normally in a short period of time. Therefore, evcome new energy cables can distinguish whether a multi-core cable is a general cable or a cable towline cable based on the comparison of general multi-core cables and cable towline cables. .
