The JGP series FRP trefoil cable cleat is purpose-built for securing three single-core high-voltage cables in a triangular (trefoil) arrangement — the standard configuration for HV single-core cable circuits. Made of fiberglass-reinforced polymer (FRP), the cleat is fully non-magnetic and electrically insulating, eliminating eddy-current losses and providing additional insulation between phases.

Key Features

• Trefoil Configuration — Holds three cables in tight triangular formation, minimizing circuit reactance and balancing short-circuit forces between phases.
• FRP Composite Body — Non-magnetic, non-conductive and spark-free; no eddy-current loss and no risk of phase-to-phase short through the cleat.
• Excellent Corrosion Resistance — Fiberglass does not rust or corrode, ideal for humid tunnels, coastal areas, chemical plants and direct-burial applications.
• High Mechanical Strength — Withstands short-circuit electrodynamic forces and long-term static load without deformation.
• Rubber Cushion Pads — EPDM pads protect cable sheaths and absorb vibration and thermal movement.
• Lightweight & Easy to Install — Significantly lighter than metal cleats; U-bolt design allows quick fastening on cable brackets and ladders.
