What does the term 'bend radius' refer to in the context of cables?

The term 'bend radius' in the context of cables refers specifically to the minimum radius around which a cable can be bent without risking damage to its structure or functionality. This is crucial for maintaining the integrity of the cable, as excessive bending can cause physical strain, impair electrical performance, or lead to breakage.

Each cable is designed with a specific bend radius which is dictated by its construction and materials. By adhering to the recommended bend radius during installation, users can ensure that the cable operates effectively and has a longer lifespan. This aspect of cable management is vital in various applications, from telecommunications to electrical systems, where maintaining optimal performance is essential.

The other choices involve attributes that do not directly pertain to how cables should be handled in terms of bending. The thickness of the cable, the weight capacity, and tensile strength are important characteristics, but they do not address the specific limitation on bending that is critical to cable installation and maintenance.
