kabeldragnings

Kabeldragnings is the process of installing cables by drawing them through conduits, ducts, or cable trays from an origin to a destination. It is a common task in electrical, telecommunications, and building services projects, involving power, data, and fiber optic cables.

The procedure begins with route planning and impact assessment, followed by installing a pull line or fish tape to guide the cable. Cables are then attached to a pulling grip or rope and drawn gradually using manual pulls or powered pullers. Lubricants may be used to reduce friction, and temporary supports or guides help maintain a safe path.

Key considerations include tension management, bend radius, and friction. Pulling tension must not exceed the cable's rated maximum; bending radii should stay within manufacturer specifications to avoid damage. Proper lubrication, gradual feeding, and monitoring of pull force help prevent kinks, crushing, or insulation damage. All work is performed with the circuit de-energized and under appropriate safety procedures.

Outcomes include a continuous, traceable installation with documented paths and cable labeling. Post-installation checks typically verify continuity and insulation, and may include diagnostic tests for data or fiber runs. The practice is governed by national electrical codes and industry standards, and performed by trained technicians.
