Q: What is the primary application of this cable?
A: Designed for industrial control circuits and power distribution in harsh environments, such as mining, construction, and renewable energy projects.Q:
Q: Why is steel wire armor used?
A: Provides mechanical protection against crushing, impact, and rodent damage, making it suitable for direct burial or exposed installations.
Q: What conductor material is used?
A: High-purity copper ensures low resistance and reliable conductivity for stable signal/power transmission.
Q: Is the PVC insulation flame-retardant?
A: Yes, it meets flame retardancy standards (e.g., IEC 60332) and resists chemicals, oils, and moisture.
Q: How many cores are available?
A: Multicore variants (e.g., 4-37 cores) allow complex wiring configurations for automation systems.
Q: Is it suitable for underground installation?
A: Yes, the steel armor and PVC sheath protect against soil corrosion and external mechanical stress.
Q: What distinguishes it from non-armored cables?
A: Enhanced durability and safety in demanding environments, though slightly heavier than unarmored alternatives.
