Viacvodiové

Viacvodiové is an adjective used in Slovak (and relatedly in Czech) to describe devices or cables that contain more than one conductor. In electrical engineering, viacvodiové cables are those built from several insulated conductors placed within a common outer jacket. This distinguishes them from single-conductor cables or coaxial constructions and is common in both power and control applications.

Construction and variations: A typical viacvodiové cable consists of multiple insulated conductors, which can be copper or aluminum, surrounded by an insulating material such as PVC or XLPE, all enclosed in a protective jacket. They may include shielding (foil or braided screen) to reduce interference, and sometimes armor or fillers to provide mechanical strength and stability. Variants include multi-core round cables, flat multi-core cables for limited space, and flexible multi-core cables designed for movable or robotized equipment. Ratings and insulation types vary to suit different voltages, temperatures, and environments.

Applications: Viacvodiové cables are widely used for electrical installations in buildings, machinery, and industrial systems where several circuits must be run together. They are employed for power distribution, motor connections, and control or instrumentation circuits. In some cases, data or signal conductors are integrated within multi-core cables, though dedicated data cables are often used where high-speed transmission is required.

Considerations: When selecting viacvodiové cables, engineers consider conductor size (ampacity), insulation material and temperature rating, voltage class, shielding needs, and environmental factors. Compliance with national and international standards and safety regulations is essential, with specific norms differing by region and application.
