Product Overview: Aluminum Cable Cleat
The Aluminum Cable Cleat (ACC Series Heavy-Duty Power Cable Clamps) is a critical cable management safety fitting designed to secure low, medium, and high-voltage electrical cables along cable trays, ladder racks, walls, and structural steel channels. Manufactured by YiHao Power, our cable cleats are engineered from high-tensile cast aluminum alloy. Designed in strict compliance with international manufacturing and safety standards for electrical cable cleats and short-circuit restraints, every Aluminum Cable Cleat protects valuable cable infrastructure against mechanical damage, gravitational sag, and catastrophic short-circuit electro-dynamic forces.

Key Performance Features of Our Aluminum Cable Cleat
- Non-Magnetic Construction Prevents Eddy Currents: Cast aluminum body is non-ferrous and non-magnetic, eliminating hysteresis heating and eddy current losses around high-current AC single-core cables.
- Short-Circuit Force Restraint: Engineered and tested to withstand high peak short-circuit fault currents, preventing cables from whipping or tearing away from mounting supports.
- Trefoil Formation Symmetry: Trefoil model holds three single-core cables in a tightly balanced triangular arrangement, minimizing magnetic induction fields and impedance imbalances.
- Cushioned Sheath Protection: High-grade EPDM rubber lining absorbs thermal expansion and contraction cycles of heavy power conductors without damaging outer PVC/XLPE insulation sheaths.
Installation Guidelines for Power Cable Restraint
Proper spacing and installation of an Aluminum Cable Cleat system guarantees maximum short-circuit protection and physical support. Follow these standard field practices:
- Determining Cleat Spacing: Calculate cleat mounting intervals based on projected system fault current levels and cable weight, typically mounting cleats every 600mm to 1200mm along cable runs.
- Tray or Channel Mounting: Secure the base plate of the cleat to the cable tray rung or strut channel using M10/M12 stainless steel mounting bolts.
- Positioning & Clamping: Lay the cable(s) onto the cushioned base, position the top cap, and tighten the side closing bolts evenly until the compression springs or rubber liners firmly grip the cable sheath without crushing it.
Primary Application Scenarios Across Power Facilities
Our premium aluminum cable cleats and trefoil clamps are widely installed across global electrical infrastructure projects, including:
- High-voltage substation transformer basements, generator risers, and switchgear rooms.
- Offshore wind turbine tower risers, marine platforms, and FPSO vessels.
- Underground utility cable trenches, tunnel raceways, and vertical shaft drops.
- Heavy industrial plants, data center main feeder lines, and solar PV central inverter connections.
Frequently Asked Questions (FAQ)
Q1: Why should single-core AC power cables be clamped using aluminum cleats instead of steel cleats?
A1: Magnetic materials like steel form a closed magnetic loop around single-core AC cables, causing severe inductive heating (eddy currents). Non-magnetic aluminum cleats eliminate this risk completely.
Q2: What is the purpose of compression springs on trefoil cable cleats?
A2: Compression springs maintain constant clamping pressure during thermal expansion and contraction of the cable sheath while absorbing sudden impact forces during a short-circuit fault.
Quality Assurance & Factory Testing
Every batch of Aluminum Cable Cleat products manufactured by YiHao Power undergoes rigorous quality control inspection before dispatch. Our testing protocols include aluminum alloy spectro-analysis, mechanical lateral load testing, short-circuit withstand simulation tests, and salt spray corrosion checks.
