Trefoil Cleats

High-Strength Nylon / LSOH / FRP Trefoil Cable Cleats for LV, MV & HV Power Cable Installations

Certa’s Nylon / LSOH / FRP Trefoil Cable Cleats are engineered to provide reliable restraint for three single-core power cables arranged in a trefoil formation. Manufactured from high-quality glass fibre reinforced polyamide (FRP / Glass Filled Nylon), these cable cleats are specifically designed to withstand high short-circuit forces while ensuring maximum cable protection and long-term durability in demanding electrical installations.

Designed for Low Voltage (LV), Medium Voltage (MV), and High Voltage (HV) power cable systems ranging from 1.1 kV to 132 kV, these non-metallic cable cleats offer exceptional resistance to corrosion, chemicals, UV radiation, moisture, and extreme temperatures. Manufactured in compliance with IEC 61914, they provide a safe, maintenance-free solution for industrial, utility, and infrastructure cable management applications.
