Cavi

Cavi is the Italian plural of cavo, meaning cables or wires. The term is used in electrical, telecommunications, and construction contexts to designate insulated conductive assemblies that transmit power or signals. In Italian technical writing, cavi are categorized by function, construction, and materials, and are specified for particular environments and safety requirements.

Common categories include power cables (for electrical power distribution), control cables (for machinery control circuits), data and communications cables (such as coaxial, twisted pair, and fiber-optic types), and automotive or shipboard harness cables. Flexible versions and armored varieties are also described for environments requiring movement or protection against physical damage.

Construction: A cable typically contains a conductor (usually copper or aluminum), one or more layers of insulation, and a protective sheath. Some cables include an outer armor or a jacket designed to resist moisture, chemicals, or fire. Conductors can be solid or stranded; insulation materials include PVC, XLPE, or rubber; outer jackets may be PVC, polyethylene, or low-smoke, zero-halogen compounds (LSZH).

Standards and regulation: European and national standards govern the design, testing, and marking of cables. In Italy, CEI standards and European EN/IEC families apply, and cables are marked to indicate conformity with safety and performance requirements. Installation practices follow local electrical codes.

Applications: Cables are used in buildings, industrial facilities, energy and data networks, consumer electronics, and vehicle systems. The term emphasizes the physical form and function of the assembly rather than a single product type.
