FAQs

1. What materials are commonly used in cable manufacturing?

Most cables use copper or aluminum conductors, along with insulation materials such as PVC, XLPE, PE, rubber, or halogen-free compounds. The outer sheath may include PVC, PE, or protective armor depending on the application.

2. What is the difference between insulation and sheathing?

Insulation protects the conductor from electrical leakage, while the outer sheath provides mechanical and environmental protection. Both are essential for cable performance.

3. How are cables tested for quality?

Cables undergo tests such as spark testing, tensile strength checks, flame-retardant tests, voltage withstand tests, conductor resistance measurement, and insulation thickness checks to ensure compliance with standards.

4. Why are fiber-optic cables gaining popularity?

They offer higher data transfer speeds, greater bandwidth, and better immunity to interference compared to metal-based cables. They are widely used in telecom and high-speed internet infrastructure.

5. What factors determine the lifespan of a cable?

Lifespan depends on material quality, environmental conditions, electrical load, installation method, and maintenance. High-quality cables installed correctly generally last longer.
