Power cables in industrial and infrastructure projects must remain securely supported throughout their service life. Cable movement caused by vibration, mechanical impact, installation stress, or electrical fault conditions can place unnecessary pressure on cables and nearby equipment. Cable cleats are designed to hold cables in position and provide dependable mechanical support.
The correct cleat depends on cable diameter, arrangement, installation environment, and the level of restraint required. This becomes particularly important with a single core cable and with three single-core cables installed in a trefoil arrangement. Understanding different Cable Cleats types, materials, and applications helps engineers and buyers choose a safer and more reliable cable-support solution.
Why Cable Cleats Matter in Electrical Installations
What Do Cable Cleats Do?
Cable cleats are mechanical supports used to secure electrical cables to trays, ladders, structures, or other mounting surfaces. Their main purpose is to prevent unwanted movement and maintain the planned cable arrangement.
During normal operation, cleats help keep cable routes stable. During vibration or electrical fault conditions, correctly selected cleats can also help restrain movement that could damage cables or terminations. Atlas Metal describes cable cleats as components used to secure and support cables while helping prevent movement caused by vibration, short circuits, and other external forces.
They are commonly considered for power plants, substations, manufacturing facilities, renewable-energy projects, infrastructure, and large commercial electrical systems.
Benefits of High-Quality Cable Cleats
Quality cable cleats provide firm support, better cable organisation, easier inspection, and improved protection against movement. They can also help reduce unnecessary strain on cable terminations by maintaining cables in their intended position.
The cleat material, cable range, fixing method, environment, and system design should therefore be considered together rather than selecting a product only by appearance or price.
Different Cable Cleats Types and Their Applications
Two-Bolt Cleats for Individual Cables
Among the common Cable Cleats types, two-bolt cleats are used to support and secure individual cables. They are suitable where each cable is installed separately and requires strong mechanical fixing.
Atlas Metal Industries currently offers aluminium two-bolt cable cleats across multiple cable diameter ranges for electrical installations.
Trefoil Cleats for Grouped Single-Core Cables
Trefoil cable cleats are designed to hold three single-core cables together in a triangular or trefoil formation. This arrangement is commonly used in three-phase power systems.
Keeping the three cables in a defined formation helps maintain consistent positioning along the cable route. The cleat must match the actual cable diameter and provide suitable restraint for the installation conditions.
Atlas Metal’s cable cleat range includes both aluminium two-bolt cleats and aluminium trefoil-type cleats.
Understanding Single Core Cable Installations
What Is a Single Core Cable?
A single core cable contains one electrical conductor within its insulation and protective layers. In a three-phase installation, three individual single-core cables may be used to carry the three phases.
A single core cable may be installed separately or as part of a grouped arrangement depending on the system design. Because each cable remains independent, suitable mechanical restraint is important for maintaining the required position and reducing unwanted movement.
Best Cable Cleats for Single Core Cable Applications
For an individually installed single core cable, a two-bolt cleat can provide secure support when correctly sized. Where three single-core cables are arranged together in trefoil formation, trefoil cable cleats are designed specifically to maintain that grouped arrangement.
Selection should be based on the cable outside diameter, cable formation, mounting conditions, and engineering requirements rather than conductor size alone.
Understanding Trefoil Cable Cleats
Advantages of Trefoil Cable Cleats
Trefoil cable cleats hold three single-core power cables in a compact triangular arrangement. This helps maintain the intended cable formation throughout the installation.
Their key benefits include:
- Stable positioning of three single-core cables
- Organised cable routing
- Efficient use of installation space
- Mechanical support against unwanted cable movement
- Consistent cable formation along the route
Where significant fault forces are expected, cleat selection and spacing should follow the project design and the required test performance.
Why Aluminium Cable Cleats Are Preferred
Aluminium cable cleats are widely selected because they offer a useful combination of relatively low weight, mechanical strength, and corrosion resistance in suitable environments.
Their lighter construction can also simplify handling during long cable runs or large industrial installations. Aluminium cable cleats are used in power distribution, utilities, machinery, infrastructure, and other industrial electrical applications.
The alloy, finish, cable range, operating conditions, and required performance should always be confirmed before selection.
