Which cable type is typically heavy-duty and used in construction and industrial settings?

Armored cable is designed specifically for rugged and demanding environments, making it especially well-suited for construction and industrial settings. This type of cable has a protective layer, usually made of metal, that provides excellent physical protection against impacts, abrasion, and other harsh conditions that can occur in these types of environments. The armored construction helps prevent damage from heavy machinery and environmental factors, ensuring the integrity and safety of electrical connections.

In contrast, flexible conduit is more about providing flexibility for installation rather than protection against severe conditions. Guy wire is primarily used for stabilizing structures like telephone poles and towers, rather than for delivering power or controlling equipment in industrial settings. Submarine cable, while robust, is specifically designed for underwater communication and power transmission and isn't applicable to typical construction and industrial environments. Thus, the heavy-duty qualities of armored cable make it the most suitable choice for these conditions.
