Temporary or permanent protection tunnels
The composite protection tunnels for HV powerline designed and manufactured by COMMET GROUP are very lightweight, making installation significantly easier and saving considerable time compared to heavy concrete tunnels that are cumbersome to handle.
They come in two versions:
- Temporary protection for the temporary securing of lines during work
- Permanent protection for the protection of lines fixed to the ground

Description
Your site gets secured very quickly.
Made from fiberglass-reinforced layered composite and dope-dyed (gray for temporary installations, off-white for permanent installations), COMMET GROUP protection tunnels are rotproof and have RTE approval.
The equipment is stackable for optimized storage.
The finish on the top surfaces features a "diamond point" nonslip texture.
How to choose?
The main criterion for choosing protection tunnels is based on the notion of temporary or permanent installation.
- The temporary fixing mode does not require anchoring the tunnels to the ground; a simple flexible link between the shields is enough.
- The permanent fixing mode involves anchoring the tunnels to the ground at four points using standard M12 anchor bolts, depending on the nature of the ground.
Permanent installations may require specific radius of curvature for the layout of the line. In this case, articulated angle shields are offered (length 500mm).
