In the realm of industrial and commercial wiring, cable glands play a pivotal role in ensuring safety, reliability, and longevity of electrical connections. Among the various types, unarmoured cable glands are widely used for flexible or PVC-insulated cables where additional mechanical protection is not required.
What Is an Unarmoured Cable Gland?
An unarmoured cable gland is a mechanical device designed to secure and terminate unarmoured cables to electrical equipment. Unlike armoured cables, these cables lack a metallic protective layer. Therefore, the primary function of the gland is to provide a tight seal, prevent cable pull-out, and ensure environmental protection (IP rating) rather than mechanical protection against crushing or impact.
Unarmoured cable glands are usually made from high-quality materials such as brass, nickel-plated brass, or stainless steel, which ensures durability and resistance against corrosion in industrial environments. They often include sealing rings, nuts, and washers to maintain a secure and safe connection.
Applications of Unarmoured Cable Glands
Unarmoured cable glands are commonly used in the following sectors:
Industrial Equipment: Providing a secure entry point for control and instrumentation cables.
Electrical Panels: Ensuring safe termination of low-voltage cables in control panels.
Lighting Systems: Protecting cables in indoor and outdoor lighting applications.
Telecommunications: Securing communication cables without the need for heavy armor protection.
Their versatility makes them ideal for environments where mechanical stress is minimal but environmental sealing (dust, water, or chemical resistance) is critical.
Benefits of Using Unarmoured Cable Glands
Ease of Installation: No need to strip or manage armoring, simplifying the process.
Cost-Effective: Less material-intensive than armoured glands, reducing overall costs.
Durability: Resistant to corrosion, chemicals, and harsh environmental conditions.
Reliable Sealing: Provides excellent protection against dust, moisture, and contaminants.
Versatility: Compatible with a wide range of cable types and diameters.
Choosing the Right Unarmoured Cable Gland
When selecting an unarmoured cable gland, consider the following factors:
Cable Type and Diameter: Ensure compatibility with the specific cable size.
Material: Choose between brass, stainless steel, or plastic depending on the environment.
Ingress Protection (IP Rating): Higher IP ratings provide better protection against dust and water.
Certification: Look for CE, ATEX, or IECEx certifications if used in hazardous areas.
