Primarily used as cable jacketing material is ______.

Primarily used as cable jacketing material is ______.

• A. Nylon
• B. PVC
• C. Teflon
• D. Rubber

Answer: (A)

The main idea is how a cable’s outer jacket protects the conductors and withstands handling. Nylon stands out because its polyamide composition gives excellent abrasion resistance, high tensile strength, and flexibility. This means cables with nylon jackets resist wear when they’re pulled, dragged, or bent, and they hold up well in environments with friction, oil, or chemicals. Those properties are especially valuable in rugged or industrial settings where the jacket must endure regular movement and contact with rough surfaces. In comparison, PVC is common and cost-effective but not as durable against abrasion as nylon, especially under repeated flexing. Teflon (PTFE) offers superb high-temperature and chemical resistance but is more expensive and not used for general-purpose jacketing. Rubber jackets exist in older or specialized cables but tend to degrade or harden with age and exposure. So nylon is the best-fitting choice for a jacket when the priority is tough, long-lasting protection in demanding conditions.
