kabelgangen

Kabelgangen is a term used in Scandinavian building and electrical design to describe a dedicated passage, channel, or corridor through which electrical cables and service lines are routed. It includes cable ducts, trays, raceways, and sometimes floor voids or raised floors. The kabelgangen is typically located in service floors, basements, or between structural elements and cladding. Its purpose is to organize, protect, and manage cabling infrastructure, facilitate maintenance and future expansion, and improve fire safety by containing cables in defined compartments rather than allowing free, exposed runs.

Structure and components commonly found in kabelgangen include cable trays or ducts made of steel, aluminum, or durable plastics, access panels or doors, and fire-stopping materials at penetrations. Documentation and clear labeling are standard to support maintenance. Design often enforces separation between high-voltage and low-voltage circuits, and may incorporate raised floors or voids for cooling, airflow, and access. Materials and fittings are chosen for durability, fire resistance, and ease of installation, with attention to proper bend radii and support spacing to prevent cable damage.

Design and safety considerations emphasize heat management, electromagnetic interference mitigation, and accessibility for inspection and repairs. Projects follow local electrical and fire-safety codes, including requirements for fire-rated assemblies, insulation, labeling, and documentation. Regular maintenance and testing are performed to ensure cable integrity and proper separation of systems.

Applications vary from residential and commercial buildings to data centers, industrial plants, ships, and offshore platforms, where kabelgangen serves as the backbone for power, control, and data distribution. In English, the concept is often referred to as cable ducts, cable trays, or cable corridors.
