These are low-voltage (0.6/1 kV), multi-core power cables constructed with:
Stranded copper conductors (Class 2),
PVC (Polyvinyl Chloride) insulation,
Galvanized steel tape armour (GSTA) for mechanical and rodent protection,
A durable PVC outer sheath (usually black and UV resistant).
The cable is robust and commonly used for fixed power distribution applications where mechanical protection and cost-efficiency are essential.
These cables are designed for:
Power distribution systems in industrial, commercial, and residential installations,
Fixed installations in cable trays, ducts, conduits, or embedded in masonry,
Underground installations, where moderate mechanical protection is required,
Indoor and outdoor use, including areas exposed to moisture and limited mechanical impact.
Not recommended for:
Environments with high continuous operating temperatures (PVC limit = 70°C),
Direct burial without additional mechanical protection in high-risk zones.
