Cable Protection

Cable protection solutions: duct systems for infrastructure projects

Cable protection ducts must withstand mechanical loads and enable clear identification. OHM offers multiple quality levels and both single‑layer and functional multilayer designs (e.g. colour stripes or a coloured outer layer). Optional longitudinal inner ribs can reduce pulling forces during cable installation.

Cost efficiency & installation methods

Depending on project requirements, quality levels and designs can be selected to support efficient installation:

• Alternative installation methods: RC variants for increased requirements (project‑dependent).
• Efficient cable installation: inner ribs (optional) help reduce pulling forces.
