Introduction to Wire and Cable Auxiliary Equipment Information

Wire and cable are wire‑based products used to transmit electrical (or magnetic) energy, convey information, and facilitate the conversion of electromagnetic energy. In a broad sense, wire and cable are often simply referred to as “cables”; in a narrower sense, the term applies specifically to non‑insulated cables, which can be defined as assemblies comprising one or more uninsulated conductors, along with their respective insulation layers, overall shielding, and outer jacket. Electromagnetic applications may also include additional uninsulated conductors. Scope of application: The primary wire and cable products used in power systems include overhead bare conductors, busbars, power cables (including plastic‑insulated cables, oil‑impregnated paper‑insulated cables—now largely replaced by plastic‑insulated power cables—and rubber‑sheathed cables), and overhead uninsulated cables.
Wire and cable are wire‑based products used to transmit electrical (or magnetic) energy, convey information, and facilitate the conversion of electromagnetic energy. In a broad sense, wire and cable are often simply referred to as “cables”; in a narrow sense, “cable” refers specifically to non‑sheathed cables, which can be defined as an assembly comprising one or more bare conductors, together with any individual sheathing layers they may have, as well as an overall protective jacket and an outer protective covering. Electromagnetic cables may also include additional unshielded conductors.
Scope of application:
The electrical wire and cable products commonly used in power systems include overhead bare conductors, busbars, power cables (plastic‑insulated cables, oil‑impregnated paper‑insulated cables—now largely replaced by plastic‑insulated power cables—rubber‑sheathed cables, and overhead insulated cables), branch cables (which partially replace busbars), magnet wires, and electrical wiring and cables for power equipment.
The wires and cables used in information transmission systems mainly include local telephone cables, television cables, electronic cables, radio-frequency cables, optical fiber cables, data cables, enameled wires, power‑communication cables, and other composite cables.
With the exception of overhead bare conductors, this category encompasses all other products, but it is primarily used for power cables, magnet wires, data cables, and instrument‑and‑metering cables.
Telecommunication cable auxiliary equipment includes wire and cable extruders, capable of extruding various types of conductors, cables, high‑temperature wires, sheaths, and steel‑wire‑coated plastics. The product line also encompasses extruders for diverse specifications of telephone cords, power cords, power cables, network cables, and BV/RV‑series residential and construction‑grade wires, as well as high‑speed extruders and computer‑cable extruders. This series of production lines features an enhanced extrusion structure designed to accommodate different processes and materials, meeting the requirements of color‑strip and color‑skin co‑extrusion, low‑smoke halogen‑free applications, and nylon‑sheath co‑extrusion.
