Shielded cables reduce wear from movement by providing

Shielded cables reduce wear from movement by providing

• A. Additional weight handling
• B. Mechanical protection and proper support
• C. Faster signal transmission
• D. Lower resistance

Answer: (B)

Movement-induced wear comes from abrasion and flexing as cables move. Shielded cables provide mechanical protection through their outer jacket and any armor, which shields the inner conductors from rubbing and damage. They also support the cable properly with strain relief and secure routing, reducing stress at terminations and bends. This combination directly minimizes wear from movement. Shielding mainly helps with reducing electrical noise, not with wear, so the aspects of carrying extra weight, speeding up signal transmission, or lowering resistance don’t address movement wear.
