Armored Cable: Maximum Bend Radius Explained

What type of cable with a corrugated sheath has a maximum bend radius of 7 times the cable diameter?

Options: A) Coaxial cable B) Fiber optic cable C) Ethernet cable D) Armored cable

Final answer:

The type of cable with a corrugated sheath that has a maximum bend radius of 7 times the cable diameter is Armored cable.

Explanation: The type of cable with a corrugated sheath that has a maximum bend radius of 7 times the cable diameter is: Armored cable (Option D). Armored cables are designed to provide mechanical protection and can have a higher resistance to environmental factors compared to other types of cables. The corrugated sheath helps in providing this extra protection and rigidity. The bend radius of a cable is important as it indicates the minimum radius you can bend the cable without damaging it or affecting its performance significantly. The maximum bend radius being 7 times the cable diameter suggests a cautious approach with a durable and likely stiffer cable, which is typical of armored cables.

To further clarify coaxial cables, these are commonly used in audiovisual connections and have different properties from armored cables. They consist of an inner conductor and an outer concentric conductor, separated by an insulating material. The construction of coaxial cables aims to shield the signal from external interferences, making them suitable for applications like cable TV connections, where maintaining the integrity of a signal is crucial.
