FAQs

1. What is the difference between PVC and XLPE insulated cables?

PVC insulated cables are cost-effective and suitable for low to medium voltage applications. XLPE insulated cables offer higher temperature resistance and better electrical properties, making them suitable for higher voltage applications.

2. What are LSZH cables and why are they used?

LSZH (Low Smoke Zero Halogen) cables produce minimal smoke and toxic fumes during a fire, enhancing safety in enclosed spaces. They are commonly used in buildings and public transportation.

3. What makes a fire-resistant cable different?

Fire-resistant cables are designed to maintain their integrity and functionality for a specified duration even under intense fire conditions. This ensures continued operation of critical systems during emergencies.

4. How do I choose the right cable for my application?

Consider the voltage rating, current carrying capacity, temperature requirements, environmental conditions, and safety standards (e.g., IEC, GB, BS) to select the appropriate cable for your specific needs.

5. Where can I find more information on Chinese cable manufacturers?

Online directories, industry trade shows like wire China, and the websites of individual manufacturers (like those mentioned above) are excellent resources for learning about Chinese cable manufacturers.
