Armoured cable constructions for underground routes exposed to soil pressure, moisture and mechanical risk.

Armoured Multi-Tube
Start with the route
The appropriate armour, sheath system and cable core are selected against soil conditions, installation method, crush requirement, rodent exposure and route maintenance risk.
Review soil, moisture, flooding, rocky terrain and expected external pressure along the route.
Choose the armour and single- or double-sheath construction around the mechanical risk.
Confirm trenching or ploughing method, pulling tension, bend limits and planned drum sections.
Available constructions
Each family is a configurable product platform. Final materials, dimensions and mechanical performance are confirmed against the approved project TDS.
