FAQ
Q. What is the maximum operating temperature of multi-core XLPE insulated copper conductor fire-proof cables?
A. The continuous operating temperature is typically 90°C (IEC 60502-2 compliant) with short-circuit withstand capability up to 250°C for 5 seconds
Q. Which fire safety standards do these cables comply with?
A. They meet IEC 60332-3-22 (flame spread in vertical installations) and IEC 60331 (fire resistance duration, e.g., 90 minutes at 750°C)
Q.Where are these cables commonly installed?
A. Critical applications include high-rise buildings (emergency circuits), subway tunnels (low-smoke requirements), and power plants (high mechanical stress areas)
Q. What is the difference between flame-retardant and fire-resistant versions?
A. Flame-retardant cables slow flame propagation (IEC 60332-1), while fire-resistant cables maintain circuit integrity during fires (IEC 60331)
Q. Can these cables be used in underground or marine environments?
A. Yes, with steel wire armor (SWA) for underground burial (IEC 60502-2) or halogen-free sheaths for marine corrosion resistance
Q. What conductor materials are available besides copper?
A. Aluminum-core variants exist (e.g., AAAC conductors) but offer lower conductivity (≈61% of copper) and higher weight
Q. How many cores can these cables have?
A. Standard configurations include 1-5 cores (single-phase to three-phase systems), with options for concentric grounding conductors
Q.Do these cables require special installation precautions?
A. Avoid sharp bending (minimum bending radius: 12× cable diameter) and overheating during welding near PVC sheaths
