FAQ
Q: What is the main purpose of using armored flame-retardant cables in low-voltage systems?
A: They provide mechanical protection (armor) against physical damage and fire resistance (flame-retardant) to enhance safety in electrical installations.
Q: How does the armor layer in these cables contribute to their performance?
A: The armor (usually steel wire or tape) protects against crushing, rodent bites, and moisture ingress while maintaining flexibility.
Q: What temperature range can low-voltage armored flame-retardant cables operate in?
A: Typically -20°C to +90°C for PVC-insulated cables and up to +130°C for XLPE-insulated variants.
Q: Are these cables suitable for outdoor installations?
A: Yes, the armor and flame-retardant properties make them suitable for outdoor use, but UV-resistant outer jackets may be required for direct sunlight exposure.
Q: What is the difference between flame-retardant and fire-resistant cables?
A: Flame-retardant cables resist flame spread but may burn, while fire-resistant cables maintain circuit integrity during a fire for a specified duration.
Q: Can armored flame-retardant cables be used in underground duct systems?
A: Yes, but additional protection like conduit may be needed in corrosive soils or high-moisture environments.
Q: What voltage ratings are covered by low-voltage armored flame-retardant cables?
A: Generally up to 1 kV (0.6/1 kV), commonly used in industrial and building power distribution.
Q: How should these cables be terminated to maintain their flame-retardant properties?
A: Use flame-retardant gland connectors and sealing compounds to prevent fire propagation through termination points.
Q: What maintenance is required for armored flame-retardant cables?
A: Regular inspections for armor damage, insulation integrity, and proper grounding are recommended to ensure long-term performance.
