APPLICATION
Low-voltage PVC (polyvinyl chloride) insulated cables are widely used in electrical systems operating at voltages below 1 kV (typically up to 1 kV AC or 1.5 kV DC).
Their versatility, cost-effectiveness, and durable properties make them suitable for a broad range of applications.

FAQ
Q: What is the maximum operating temperature for PVC insulated cables?
A: PVC insulation typically withstands up to 70°C continuous operation, with short-term peaks of 160°C per IEC 60502 standards.
Q: Are PVC-sheathed cables suitable for outdoor installations?
A: Yes, but UV-resistant PVC compounds are recommended for direct sunlight exposure to prevent degradation.
Q: What are the key advantages of PVC in power cables?
A: Cost-effectiveness, flexibility, flame retardancy (halogen-free options available), and ease of installation.
Q: Can PVC cables be used in wet or underground environments?
A: Yes, when equipped with water-blocking materials and proper moisture-resistant PVC formulations.
Q: What voltage ratings do PVC power cables support?
A: Typically up to 1 kV (0.6/1 kV rating per IEC 60227), with some designs reaching 3.6 kV.
Q: How does PVC compare to XLPE insulation for power cables?
A: PVC offers better flexibility and chemical resistance, while XLPE provides higher thermal capability (90°C continuous).
Q: Are PVC cables recyclable?
A: Yes, PVC is fully recyclable through mechanical or thermal processes, with industry recycling rates exceeding 90% in Europe.
Q: What is the minimum bending radius for PVC cables?
A: Generally 6-8 times the outer diameter (e.g., 4D for armored cables) to avoid insulation damage.
Q: Do PVC cables require special termination techniques?
A: Standard heat-shrink or cold shrink terminations work, but peel-back PVC layers to ensure proper conductor contact.
Q: How can I identify PVC-sheathed cables in conduit systems?
A: Look for markings like "PVC/PVC" or "90°C" on the sheath, and confirm via flame tests (self-extinguishing properties).
