Power Cable Cleats: Securing Cables at All Voltage Levels

A power cable cleat is used to securely fasten power cables to their supports in substations, electrical stations, cable trays, or tunnels. Unlike a standard plastic cable tie, this type of cable cleat is specifically designed to withstand the intense mechanical forces generated during a short circuit. KOZ cable cleats cover all fastening requirements, from single low-voltage cables to high-voltage multicore cable arrangements.

What Is a Power Cable Cleat?

A power cable cleat is a mechanical fastening component designed to secure one or several cables onto a supporting structure. It ensures long-term cable retention, proper conductor spacing, and installation safety, even in demanding environments (outdoor installations, saline atmospheres, vibrations).

The Role of an Electrical Cable Cleat

Beyond simply holding cables in place, cable cleats organize cable routing, reduce mechanical stress on conductors, and facilitate maintenance operations. In power networks, they are considered a critical safety component.

Withstanding Electrodynamic Forces During Short Circuits

During a short circuit, cables are subjected to considerable repulsion forces. A power cable cleat must hold conductors firmly in place to prevent movement or damage. This is what fundamentally differentiates an industrial cable cleat from a standard cable tie.

The trefoil configuration groups three single-core cables in a triangular arrangement. This setup optimizes mechanical resistance and reduces electrical losses. The KOZ TRI cable cleat is specifically designed for this configuration.

Single-Core or Flat Formation Fixing

For a single cable or multiple cables installed side by side in flat formation, other configurations are more suitable: single cable cleats or multi-tier fixing systems, depending on the number of conductors and the required spacing.
