Understanding The Critical Role Of Cable Cleats in Data Centres
March 31st, 2025
Do You Need Cable Cleats in Data Centres?
In an increasingly digital world, Cable Cleats in Data Centres are crucial in support of the backbone of global connectivity. Every click, transaction, and streamed video relies on complex Data Centre infrastructures operating seamlessly. As the demand for high-speed data and reliable uptime continues to grow, so too does the need for robust electrical infrastructure. Among the often-overlooked yet crucial components of Data Centre design is cable management – ensuring that LV MV HV Power Cables and data cables are installed, protected, and maintained to the highest standards.
What is a Cable Cleat?
Cable Cleats are devices used to secure, fix, strap and support electrical power cables in an installation, ensuring safe operation and prevention of damage or injury, specifically in the event of a short circuit. Cable Cleats in Data Centres are ultimately purposed to increase/enhanced safety, organisation, cable protection, containment and ensure optimal performance. Typically, Cable Cleats are designed to be attached to various surfaces, such as ladders, trays, struts, rails, or beams.
LV MV HV Power Cable Management in Data Centres
Modern data centres are high-density environments where vast amounts of power are distributed through extensive cabling systems. These installations face several key challenges:
- High Power Demand: Data Centres require vast amounts of electrical power, leading to high-capacity cabling systems that must be properly supported and secured.
- Thermal Management: Poor cable management with no Cable Cleat usage can obstruct airflow, leading to overheating and reduced efficiency.
- Fire Safety: Electrical faults, if not properly contained, can pose a serious risk to critical infrastructure and personnel. Regulations require secure cable installation to prevent short circuits and mitigate fire hazards.
- Maintenance and Upgrades: Well-organised cabling simplifies maintenance and reduces downtime as data centres are continually evolving.

Cable Cleats Critical Role in Ensuring Safety and Performance
Cable Cleats, Clamps & Hangers play a fundamental role in securing electrical power cables, particularly in high-voltage environments. While they may be a small component of the overall electrical system, their importance cannot be overstated. Cable Cleats in Data Centres provide vital protection by:
- Protection during Short Circuits and Electrical Failures: In the event of a fault, the forces generated by high-powered electrical cables can be immense. Without proper restraint, power cables can move violently, leading to catastrophic failures. Cable Cleats hold cables in place, mitigating these risks.
- Ensuring Compliance with Industry Standards: International regulations, such as IEC 61914 Power Cable Standards, set stringent requirements for cable fixing and restraint systems. High-quality cable cleats ensure compliance with these safety standards.
- Aiding Thermal Management: Securely spaced cables allow for improved airflow and more efficient heat dissipation, contributing to the overall energy efficiency of a Data Centre.
- Enhancing Longevity and Reliability: Properly restrained cables experience less wear and tear over time, reducing the likelihood of maintenance issues and unplanned outages.
How Do You Choose the Right Cable Cleats for Data Centres?
Not all Cable Cleats are created equal, and selecting the right product for a Data Centre environment requires careful consideration to provide optimal LV MV HV power cable support. Key factors include:
- Performance Under Fault Conditions: Cleats must be tested under high short-circuit conditions to ensure they provide adequate restraint in the event of a fault.
- Material Selection: Corrosion-resistant materials such as stainless steel or high-strength polymers are ideal for ensuring longevity.
- Installation Flexibility: Data centres often require custom cable arrangements, so cleats should allow for easy installation and adaptability to different configurations.

Cable Cleats, Clamps & Hangers
Cable Cleats in Data Centres aren’t necessarily the most visible component. However, Cable Cleats, Clamps & Hangers play an indispensable role in securing the power supply that keeps the digital world running from Data Centres. A well-designed support system incorporating compatible Cable Cleats protects infrastructure while contributing to operational efficiency and regulatory compliance.

Ellis Emperor Cable Cleats | Sunrise Wind Offshore Wind Farm Case Study
November 9th, 2023
Cable Cleats Offshore Windfarm
Windfarm cable cleats
Ellis Patents, a global leader in the manufacture and innovation of cable cleats, including the Emperor and Flexi Straps range are being installed in the first offshore windfarm in the USA to use a high voltage direct current system (HVDC) to deliver power onshore; the advantages of HVDC are as follows:
- the ability to interconnect networks that are asynchronous
- the ability to transmit power over long distances without technical limitations
- the ability to control power flows on the HVDC connection for all system backgrounds
- the ability to transmit power in either direction as desired by the network operator
- in certain cases the ability to improve AC system stability
The Sunrise Wind Offshore Wind Farm is a significant step towards New York’s clean energy goals. When it is completed the 800MW windfarm will power nearly 600,000 households with renewable electricity by 2025 and help New York accomplish a carbon-free energy grid by 2040.

Sunrise Wind Offshore Wind Farm
Ellis Patents Offshore Wind Project
Experts at Ellis Patents worked closely with the UK Design Team on this. This ensured the highest safety standards and optimal cable management on the offshore platform.
Furthermore, the platform is characterised by a steel jacket substructure and a topside deck housing essential electrical equipment and is the heart of the windfarms operations.
Kelly Brown Ellis Patent’s Sales Director made a statement on this. She said: “Sunrise Wind is a major project for the advancement of the wind sector in the US and having Ellis Cable Cleats installed gives us a huge feeling of pride to be involved in something on such a global scale. This clearly demonstrates the trust in Ellis’ expertise in cable management to enhance safety and efficiency in the offshore platform”.
The Offshore Converter Station is designed to collect the 66kV alternating current (AC) power generated by the wind turbines, relies on a robust subsea export cable that spans an impressive 100 miles to connect to the onshore converter station located at Holbrook on Long Island. The onshore converter station plays a vital role in converting the power back to AC before feeding it into the distribution grid, ensuring clean energy reaches homes, industries, and other end-users across New York.
Cable Management Solution for Sunrise Offshore Windfarm
Ellis provided a cable cleat and management solution tailored to the unique performance requirements of the Sunrise Wind Project.
The Ellis Patents Cable Cleats and Flexi-Straps were installed in the first offshore wind farm. This also played a pivotal role in securing and supporting the cables in the challenging offshore environment.
