What is Cable Wire? Who are the domestic and international manufacturers of Cable Wire?

First, what is a cable cable? A cable wire is an electrical device used to transmit power, data or signals, and usually consists of one or more conductors, insulation, an insulating shell and a support material. Cable cables are used in a wide range of applications, from the home to industry, transportation, communications and energy. The history of cables and cables can be traced back to the 19th century, when people began using electricity for lighting and other industrial applications. The earliest cables and cables were insulated with rubber or pulp, which were quickly phased out due to their instability and flammability. Today, modern cable cables utilize a variety of high-performance insulation materials such as polyethylene, polyvinyl chloride, cross-linked polyethylene, and rubber to provide better insulation, heat resistance, and durability. Definition of Cable CablesCable cables are a combination of multiple insulated conductors and cladding layers that form an electrical transmission device. Its function is to transmit information such as electricity, signals and data. Cable cables are usually made up of conductors, insulation, and outer sheath from the inside to the outside. Among them, the conductor is responsible for the transmission of electrical energy or signals, the insulation layer is mainly used to prevent electric shock between the conductors, and the outer jacket protects the insulation layer from mechanical damage. The structure of the cable cable cable mainly consists of conductor, insulation, outer sheath and other parts of the composition. 1. conductor conductor is one of the most important components of the cable cable, usually made of copper, aluminum and other materials. The conductor is responsible for the transmission of power or signal, and its cross-sectional area determines the conductivity of the cable. At the same time, the larger the cross-sectional area of the conductor, the smaller the resistance of the cable, the higher the efficiency of the transmission of electrical energy.2. Insulation layer Insulation layer is the protective layer of the cable, mainly used to prevent the conductor between the electric shock. Insulation is usually made of polyethylene, PVC and other materials. Different insulating materials have different insulation properties and characteristics, such as high temperature resistance, corrosion resistance, wear resistance, etc. 3. outer sheath outer sheath is the cable cable's external protective layer, mainly used to protect the insulation layer from mechanical damage and environmental impact. The outer jacket is usually made of PVC, polyethylene and other materials. Different outer jacket materials have different wear resistance, corrosion resistance, waterproof, fire and other characteristics. 4. filler filler is an important part of the cable cable, cable cable has many types, according to the use and structure can be divided into the following categories: power cable cable: used to transport high-voltage power and low-voltage power, including power cables and control cables. Communication cables and cables: used for the transmission of telephone, data, images and video and other information, mainly including fiber optic cables and coaxial cables. Signal cables and cables: used to transmit low-voltage, low-power signals, such as audio, video, computer networks, sensors, etc., mainly including twisted-pair cables, shielded cables, coaxial cables and so on. Specialty cables and cables: used for applications in special fields, such as ships, petroleum, chemical, medical and other fields of special needs, including submarine cables, fire-resistant cables, low-smoke halogen-free cables and so on. In the manufacturing process of cables and cables, first of all, it is necessary to design and select suitable insulating materials and conductor materials, and produce them according to specifications and standards. Subsequently, the conductors are insulated and braided or wrapped to form the core of the cable wire. The core is then combined with the outer jacket to form the final form of the cable.
