FAQ
What is the primary purpose of a single-core low voltage cable with steel tape armor (STA)?
Designed for fixed installations in industrial and commercial settings, STA cables provide robust mechanical protection against external damage, ensuring reliable power distribution in harsh environments.
What voltage rating is suitable for this type of cable?
These cables are rated for 0.6/1kV (600/1000 volts), making them ideal for low-voltage applications such as building wiring and machinery connections.
Why is PVC insulation used in these cables?
PVC insulation offers cost-effectiveness, flexibility, and durability, making it perfect for indoor or protected outdoor installations where environmental stress is moderate.
How does steel tape armor enhance cable performance?
The steel tape layer provides superior resistance to mechanical impact, crushing, and rodent attacks, extending cable lifespan in high-risk areas like underground or exposed tunnels.
What are the current-carrying capacities of these cables?
A 10mm² single-core STA cable typically handles up to 60–80 amps, depending on installation conditions, supporting high-power circuits like air conditioning units.
Where are these cables commonly installed?
Used in industrial plants, urban power networks, and commercial buildings, especially where durability against physical damage is critical.
Are these cables suitable for underground use?
Yes, STA design with PVC insulation and steel armor makes them ideal for direct burial or underground conduits, resisting moisture and soil pressure.
