LVAV Cable

LVAV (Low Voltage Aluminum Armoured) cables are engineered for demanding power distribution applications requiring maximum protection against mechanical damage. Featuring aluminum conductors with PVC insulation and double galvanized steel tape armour, these cables deliver reliable performance in harsh environments while providing excellent protection against crushing, impact, and rodent damage.

Primary Applications

Underground Installation

• Direct burial: Underground power distribution without additional conduit protection

• Utility networks: Municipal and industrial underground electrical systems

• Substation connections: Power distribution from substations to load centers

• Industrial sites: Underground power supply for manufacturing facilities

Harsh Environment Applications
