Available for Single Type, Trefoil Type and Quad Type.
Why does Trefoil Cable Cleats Stainless Steel so important? The core function of stainless steel cable clamps is to secure high-voltage cables during short-circuit faults, resisting enormous electrodynamic forces and preventing cable displacement, swinging, and damage. IEC 61914 Trefoil Cable Cleats are engineered for secure cable retention and short circuit protection in medium and high-voltage power systems.
Manufactured from non-magnetic 316L stainless steel and tested in accordance with IEC 61914 standards, Yokelink Trefoil Cable Cleats provide outstanding resistance to electromechanical forces, corrosion, vibration, and extreme environmental conditions.
Trefoil Cable Cleats 316L Stainless Steel IEC 61914:2021 Certificated Application :
Trefoil Cable Cleats are widely used in metro and railway tunnels, power substations, offshore oil & gas platforms, marine vessels, renewable energy projects, battery energy storage systems (BESS), wind farms, solar power stations, industrial plants, and data centers.
For tunnel and railway applications, the LSZH (Low Smoke Zero Halogen) liner helps improve fire safety and reduce smoke emission in confined environments. In offshore and marine projects, the 316L stainless steel structure delivers superior corrosion resistance against salt spray and harsh weather conditions.
For substations and utility power networks, YOKELINK Trefoil Cable Cleats provide reliable cable restraint under high short-circuit fault currents, ensuring safe and stable cable installations. In renewable energy and industrial facilities, Trefoil Cable Cleats support long-term outdoor durability, UV resistance, and vibration protection for critical power cables.

Trefoil Cable Cleats use 316L non-magnetic stainless steel and LSZH (Low Smoke Halogen-Free) gaskets,
ensuring compliance in harsh environments such as marine and oil/gas spill conditions.
3. Installation Compatibility:
The mounting hole design references mainstream international standards,
allowing direct installation on existing Panduit or Ellis dedicated cable trays for seamless switching.
How to select Cable Cleats?
1. Know the Cables
- Which type of cable is being used, Single or Multi-Conductor?
- What is the outer diameter of Cables?
- What is the available short circuit current (RMS or IP Peak) of the cable?
- If a ground wire is installed in the cleats, know the outer Diameter of the ground wire.
2. Know the System and Cleat Types
- What is the cable formation, Single or Trefoil?
- What type of the cable tray is installed?
How to install the cable cleats?
1. Remove the top plastic spacer to expose the bolt hole.
2. Place the cleat over the corresponding hole on the rung.
3. Insert the supplied carriage bolt through the hole at the bottom of the cleat.
4. Secure the bolt with the included nut and washer.
