Kanavaputki

Kanavaputki, literally meaning “channel pipe” in Finnish, refers to a conduit pipe designed to protect and guide cables and wires through building structures or outdoor environments. The term is used across electrical, telecommunications, and civil engineering contexts. Kanavaputki is part of a broader ducting system (kanavaputkisto), which houses multiple conduits to organize services in a controlled manner and facilitate cable maintenance.

Materials and construction: Kanavaputki is commonly manufactured from plastics such as PVC or polyethylene for indoor and outdoor use, though steel or other polymers may be used in high-load or outdoor environments. It may be rigid or corrugated for flexibility. Joints and fittings, including elbows, tees, couplings, and pull boxes, allow changes in direction and access points for installation and maintenance. Diameters vary to accommodate different cable cross-sections and are compatible with standard sized cables.

Applications: Kanavaputki is used to route electrical power lines, fiber and copper communication cables, and other services in both new constructions and renovations. In urban infrastructure projects, a network of kanavaputki can be installed in advance beneath sidewalks, roads, or building floors, providing a protected pathway for later cable deployment. The system is designed to protect cables from mechanical damage, moisture, and soil movement, and to simplify cable replacement or upgrades.
