How These Simple Cable Cleats Prevent Major Disasters – Proven Facts!

The tiny device that protects your entire electrical system.

April 24, 2025

When it comes to electrical safety, it's often the small components that make the biggest difference. Cable cleats might seem insignificant, but these simple devices play a critical role in preventing electrical accidents, fires, and system failures. Whether you're installing them in a commercial facility or a high-voltage industrial site, cable cleats are your first line of defense against disaster.

Let’s explore exactly how they work, why you need them, and how to make the right choices for your project.

🔌 What Are Cable Cleats and Why Do They Matter?

Cable cleats are mechanical supports that securely hold electrical cables in place. Installed on cable tray systems, they protect cables from movement due to electrical faults, thermal expansion, or external impact.

Without them, loose cables can whip violently under fault conditions—causing electrical fires, equipment damage, or even injury.

⚠️ Real-World Disasters Caused by Missing or Poorly Installed Cable Cleats:

Arcing and fire in data centers due to short-circuit cable movement
Major power plant shutdowns caused by dislodged high-voltage cables
Industrial injuries from cable whiplash in fault conditions

✅ How These Simple Devices Prevent Catastrophe

Here’s how properly selected and installed cable cleats prevent dangerous scenarios:

1. Containment During Short Circuits

Cleats hold cables in place during a short-circuit event, preventing dangerous movement or collisions.
Especially critical in high-voltage environments like substations and power plants.

2. Protection From Wear and Tear

Prevent chafing and mechanical stress caused by vibration or thermal expansion.

3. Fire Risk Reduction

Fire-resistant cleats can prevent flames from spreading along cable routes.

4. Compliance with Safety Standards

Using certified cable cleats helps you meet IEC 61914 and NEC standards for cable installations.

🧠 How to Choose the Best Cable Cleats Manufacturer for Your Electrical Project

Not all cleats are created equal. Choosing a reliable manufacturer is just as important as selecting the right product.

🔍 Key Factors to Look For:

Proven Compliance with IEC 61914
Heavy-Duty Options for high-voltage and outdoor systems
Customization for unique tray configurations
Strong brand reputation (e.g., Ellis Cable Cleats)

Tip: North American Sales Company offers premium-quality cleats, including the globally trusted Ellis Cable Cleats, backed by decades of experience.

🛠️ How to Install Cable Cleats on a Cable Tray, Step by Step

Want maximum safety? Correct installation is essential.

Step-by-Step Installation Guide:

Assess the Cable Layout

Know your voltage rating, fault level, and tray spacing.

Choose the Right Cleats

Match cleat type (trefoil, single, or double) with cable configuration.

Mark Cleat Positions

Follow spacing guidelines based on short-circuit rating.

Secure Cleats to the Tray

Use approved fasteners and ensure alignment.

Lock Cables in Place

Make sure cables are snug but not overly compressed.

Inspect and Test

Confirm tightness, position, and mechanical strength.

Pro Tip: Use trefoil cleats for three-core cables in high-voltage settings to enhance containment.

🌐 When Simplicity Saves Lives

These aren’t just accessories—they’re lifesavers. Ignoring cable cleats in your design can lead to massive losses in money, time, and safety. From choosing a reputable manufacturer to installing them correctly, every step ensures your electrical system is robust, compliant, and safe from disaster.

❓ Frequently Asked Questions

Q1: Are cable cleats necessary for low-voltage installations?

Yes. While high-voltage systems face more risk, even low-voltage installations benefit from proper cable restraint and fire safety.

Q2: What’s the difference between plastic and metallic cleats?

Plastic cleats are lightweight and corrosion-resistant, ideal for indoor use. Metallic cleats offer superior strength and are better suited for industrial and outdoor applications.

Q3: Can I install cable cleats on an existing tray system?

Absolutely! Retrofit installations are common and ensure continued safety for aging systems.
