Why Unarmoured Cable Glands Are Essential for Electrical Installations

 


Introduction

Unarmoured Cable Glands are essential components used to secure, seal, and protect unarmoured cables, which lack the internal steel or metallic armor found in armored cables. These cable glands are designed to provide strain relief, environmental sealing, and electrical continuity where necessary. Unarmoured cable glands are commonly used in industrial, commercial, and residential applications where cables need to pass safely through enclosures, panels, or equipment without the extra layer of mechanical protection that armored cables provide.

What Are Unarmoured Cable Glands?

Unarmoured cable glands are mechanical devices that attach and secure cables to electrical enclosures or equipment. They provide sealing, strain relief, and environmental protection, ensuring that cables remain securely fastened while preventing dust, moisture, or debris from entering the enclosure. Unlike cable glands for armored cables, these are specifically designed for cables without internal protection layers, making them ideal for non-hazardous environments where mechanical protection isn't necessary.

Key Features of Unarmoured Cable Glands

1.      Strain Relief
These glands provide essential strain relief by preventing cables from being pulled or dislodged from equipment or junction boxes. This is particularly important in environments where movement, vibration, or stress on cables is a concern.

2.      Environmental Protection
Unarmoured cable glands offer sealing protection against environmental factors such as dust, moisture, and chemicals, ensuring that cables remain protected from external hazards. This helps to maintain the integrity of electrical connections.

3.      Ease of Installation
Unarmoured cable glands are designed for easy installation and come with various options such as threaded, compression, and push-fit designs, depending on the specific application.

4.      Corrosion Resistance
Made from materials such as nylon, brass, or stainless steel, unarmoured cable glands offer high resistance to corrosion, ensuring long-term performance in a range of environments.

Applications of Unarmoured Cable Glands

·         Electrical Enclosures
These cable glands are used in industrial and commercial settings to connect unarmoured cables to electrical enclosures, ensuring a safe and secure connection.

·         Control Panels
In control panels, unarmoured cable glands provide a secure entry point for cables while maintaining the panel’s sealing and integrity.

·         Residential Installations
Unarmoured cable glands are often used in residential wiring systems, where mechanical protection of the cable is not required, but environmental sealing and strain relief are still needed.

·         Telecommunications
These cable glands are used in communication and data systems, providing secure and protected connections for cables in non-hazardous environments.

Advantages of Unarmoured Cable Glands

1.      Cost-Effective
Since unarmoured cable glands do not require the extra components needed for armored cables, they are often more cost-effective while still providing essential protection.

2.      Versatility
Unarmoured cable glands are available in a wide range of materials and sizes, making them suitable for various applications across different industries.

3.      Durability
Despite being designed for cables without internal armor, these glands offer excellent durability and are capable of withstanding harsh conditions, thanks to their high-quality construction.

Conclusion

Unarmoured cable glands are vital for ensuring the secure and reliable connection of unarmoured cables in a wide variety of applications. They provide essential protection against strain, environmental factors, and mechanical damage, making them indispensable in both industrial and residential settings. Whether you're working with control panels, telecommunications, or general electrical installations, unarmoured cable glands ensure the safety and performance of your cable systems.
