A cable is a conduit used for the transmission of electricity. Cables are generally used for simple construction and automotive wires, and as energy transmission cables, the complex structure of the cable is beyond doubt. According to the target function, the cables have the following characteristics: construction and automotive wires are light, mass-produced, low in price, equivalent in electrical and mechanical properties, and long in aging resistance; industrial wires must meet customer requirements; energy transmission cables are a high-tech product. Cable Wire Construction The construction of the various cables is very different and in some cases the various cables must be bundled together to form a composite cable. Cable styles for various constructions and applications. We can cite a few examples to show the wide variety of cables available in the market. Power Transmission Cables: Cables for power transmission and distribution networks are divided into high and extra high voltage types, medium voltage types. Low-voltage cables are used for the distribution and connection of aviation and subway power networks; household cables and vehicle equipment connection lines (maximum rated voltage 750V), industrial equipment cables and vehicle equipment power cables (maximum rated voltage 1000V). Special cables: Special cables for electronic equipment such as automobiles, airplanes, cranes, ships, machine tools, railways, mines, control systems, petrochemicals, oil production equipment, steel industry, welding, etc.; precision data transmission wires for computer equipment, electronic instruments, and automatic control equipment; Electric heating wire; credit cable. Medium and long-distance wires for aviation and subways; LAN information exchange wires for aviation and subway operation stations; telephone lines; wires installed by users themselves; submarine and underwater cables: power cables; communication wires; power transmission cable connection accessories: low-voltage connectors and Splitters; medium voltage terminals; medium voltage plug-in terminals for connectors, bushings; dry insulated wires or paper insulated wires, folded cables, extruded cables, heat shrinkable cables, etc. medium voltage connectors and splitters; dry Prefabricated medium voltage connectors for insulated cables; high voltage and extra high voltage terminals and connectors. The market shares of various cables are roughly as follows: 65% are used for power transmission cables, 50% are low-voltage types, 15% are medium-high voltage types; 25% are used for communication wires; 10% are used for other cables;
