Power Distribution Networks
Widely used in urban underground power grids, industrial parks, and substation connections for medium-voltage (0.6/1kV) power transmission.
Suitable for both overhead and underground installations due to its armored (steel tape armor) structure.Industrial Facilities
Deployed in manufacturing plants, oil refineries, and chemical industries where flame-retardant (ZC grade) and mechanical protection (YJV22) are required.
Commonly connects motors, transformers, and switchgear in harsh environments.Infrastructure Projects
Essential for metro systems, tunnels, and bridges where cable durability against crushing (double steel armor) and fire resistance are critical.
Complies with IEC/GB standards for public safety projectsConductor:Class 1 or class 2 stranded Copper conductor
Insulation:Cross-Linked Polyethylene(XLPE)
Inner sheath:Polyvinyl chloride (PVC)
Armour:Single core: Steel Tape Multi core: Galvanized Steel Tape
Outer sheath: Polyvinyl chloride (PVC)

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.
