The Importance of Cable Gland Armoured in Industrial Applications


Cable glands are indispensable components in the wiring and cabling industry, offering secure and reliable connections. Among the various types of cable glands available, Armoured Cable Glands stand out for their robust construction and ability to handle challenging environments. At Cabex India, we specialize in providing high-quality cable management solutions, including cable glands tailored for armoured cables. In this detailed guide, we delve into every aspect of armoured cable glands to ensure your installations are efficient and durable.

What is an Armoured Cable Gland?

An armoured cable gland is specifically designed to terminate armoured cables securely. These cables, reinforced with a layer of steel wire or tape, are commonly used in industrial, hazardous, and outdoor settings due to their enhanced protection against mechanical damage. Cable glands ensure proper grip, strain relief, and electrical continuity, making them an essential component in maintaining the integrity of armoured cable installations.

Key Features of Armoured Cable Glands

  1. Durability: Made from materials like brass, stainless steel, or aluminum, armoured cable glands are built to withstand harsh conditions, including extreme temperatures, corrosion, and physical stress.
  2. Electrical Continuity: These glands are equipped to maintain the electrical bonding of the cable’s armour, ensuring a reliable grounding path.
  3. IP Ratings: High ingress protection (IP) ratings, such as IP66, IP67, or IP68, offer excellent protection against dust, water, and other environmental contaminants.
  4. Ease of Installation: Designed for quick and secure fitting, armoured cable glands reduce installation time while maintaining performance standards.

Applications of Armoured Cable Glands

Armoured cable glands are widely used in various industries, including:

  • Oil and Gas: For safe connections in explosive and hazardous environments.
  • Power Distribution: Ensuring the reliable transmission of electricity across grids.
  • Marine and Offshore: Providing corrosion-resistant solutions for cables in marine applications.
  • Construction: Protecting electrical systems in commercial and residential buildings.
  • Renewable Energy: Ensuring secure connections in wind and solar power installations.

Types of Armoured Cable Glands

1. BW Glands

BW glands are used for indoor applications and are suitable for single-wire armour cables. They provide electrical continuity and a secure grip for the armour wires, ensuring a robust installation.

2. CW Glands

CW glands are ideal for outdoor applications. They offer excellent sealing and are designed for double-wire armour cables, ensuring both mechanical and environmental protection.

3. E1W Glands

E1W glands are versatile and suitable for indoor and outdoor use. Their design provides superior sealing and strain relief, making them a preferred choice in demanding environments.

4. Flameproof/Explosion-Proof Glands

These glands are specifically engineered for hazardous areas where there is a risk of explosion. They are certified to meet stringent safety standards and prevent the ingress of flammable gases.

How to Choose the Right Armoured Cable Gland

Selecting the right cable gland for your armoured cable involves considering several factors:

  1. Cable Type: Ensure the gland is compatible with the specific type of armoured cable in use.
  2. Material: Choose materials that match the environmental conditions, such as brass for general use or stainless steel for corrosive environments.
  3. Ingress Protection: Verify the gland’s IP rating to ensure it meets the required protection level.
  4. Size: Ensure the gland fits the cable’s diameter and armour type.

Installation Process of Armoured Cable Glands

Proper installation of armoured cable glands is critical for their performance. Follow these steps for a secure and effective installation:

  1. Prepare the Cable: Strip the cable to expose the conductors, armour, and insulation. Trim the armour layer to ensure a neat fit.
  2. Insert the Cable: Pass the cable through the gland body and position the armour wires within the gland’s cone.
  3. Secure the Armour: Tighten the gland to grip the armour firmly, ensuring electrical continuity and strain relief.
  4. Seal the Gland: Use the gland’s sealing mechanism to protect against ingress of dust and moisture.
  5. Test the Connection: Verify the electrical continuity and mechanical strength of the installation.

Benefits of Using Armoured Cable Glands

  • Enhanced Safety: Ensures proper grounding and prevents electrical faults.
  • Extended Lifespan: Protects cables from mechanical damage and environmental factors.
  • Cost-Effective: Reduces maintenance costs by ensuring reliable performance over time.
  • Regulatory Compliance: Meets industry standards for safety and performance.

Common Challenges and Solutions

1. Compatibility Issues

Ensure that the gland size matches the cable dimensions to avoid installation problems.
Solution: Use sizing charts and manufacturer recommendations.

2. Corrosion in Harsh Environments

Corrosion can compromise the gland’s performance.
Solution: Opt for stainless steel glands for high-corrosion areas.

3. Improper Sealing

Poor sealing can lead to moisture ingress and electrical faults.
Solution: Use glands with certified IP ratings and follow installation guidelines.
