A Comprehensive Guide to Choosing the Right Cable Gland Armoured
Armoured Cable Glands are critical components in electrical installations, ensuring secure terminations for armoured cables while maintaining safety and reliability. Designed to meet industrial standards, these glands protect against mechanical stress, environmental hazards, and electrical faults. At Cabex India, we are committed to providing superior solutions for all cable management needs, including armoured cable glands that guarantee optimal performance.
What Are Armoured Cable Glands?
Armoured cable glands are specialized fittings that secure and terminate armoured cables. These cables feature an additional protective layer, typically steel wire or tape, to shield them from mechanical damage. The gland connects this armour layer to the electrical system, providing strain relief, grounding continuity, and environmental sealing.
Armoured cable glands are essential in applications where durability, safety, and compliance with regulations are priorities.
Features of High-Quality Armoured Cable Glands
Robust Construction: Manufactured using durable materials like brass, stainless steel, or aluminum to withstand mechanical wear and harsh environments.
Waterproof and Dustproof: High ingress protection (IP66/IP68) ensures resistance to water and dust, making them suitable for outdoor and industrial use.
Strain Relief: Protects cables from mechanical tension, ensuring longevity.
Corrosion Resistance: Surface treatments or choice of material prevents corrosion in challenging conditions like marine or chemical industries.
Versatility: Compatible with a wide range of armoured cable sizes and types.
Applications of Armoured Cable Glands
Armoured cable glands are indispensable across numerous industries:
Energy and Power: Ideal for transmitting electricity safely in power grids.
Oil and Gas: Used in hazardous zones for secure and explosion-proof connections.
Manufacturing Plants: Protecting equipment in heavy industrial environments.
Telecommunications: Ensuring reliability in communication cables.
Marine and Offshore: Offering corrosion-resistant solutions for aquatic settings.
Types of Armoured Cable Glands
1. BW Armoured Cable Glands
These glands are ideal for indoor use and provide excellent grip for single-wire armour (SWA) cables. BW glands are widely used for non-hazardous applications.
2. CW Armoured Cable Glands
CW glands are designed for outdoor applications and offer superior sealing properties. They are suitable for environments requiring additional environmental protection.
3. E1W Armoured Cable Glands
Known for their high performance, E1W glands provide enhanced sealing and strain relief, making them suitable for indoor and outdoor installations.
4. Flameproof Armoured Cable Glands
Specifically engineered for hazardous environments, these glands prevent the entry of explosive gases and are certified for use in ATEX or IECEx zones.
Benefits of Using Armoured Cable Glands
Safety Assurance: Provides grounding continuity and prevents electrical hazards.
Environmental Protection: High IP ratings ensure resistance to moisture, dust, and extreme temperatures.
Durability: Prolongs the life of cables by protecting against mechanical wear.
Regulatory Compliance: Meets industry standards for safety and performance.
Reduced Downtime: Prevents failures and ensures uninterrupted operations.
Choosing the Right Armoured Cable Gland
When selecting an armoured cable gland, consider the following:
Cable Type: The gland must match the type of armoured cable (e.g., single-wire or double-wire armour).
Material: Choose a material based on the environment. Brass is common, while stainless steel is better for corrosive conditions.
IP Rating: For outdoor or hazardous applications, ensure the gland has an IP68 rating or higher.
Certification: Look for certifications like ATEX, IECEx, or UL for hazardous areas.
Size: Use sizing guides to match the gland to the cable diameter.
How to Install an Armoured Cable Gland
Installing an armoured cable gland is a straightforward process but requires precision. Follow these steps for successful installation:
Cable Preparation: Remove the cable's outer sheath to expose the armour and inner conductors. Ensure a clean cut for a secure fit.
Insert the Gland Body: Slide the gland onto the cable, ensuring proper alignment with the armour layer.
Secure the Armour: Tighten the gland’s components to grip the armour wires firmly, ensuring strain relief and electrical continuity.
Seal the Connection: Use the gland’s sealing mechanism to protect against environmental factors like moisture or dust.
Final Inspection: Verify that the gland is securely attached, and test for electrical continuity to ensure proper grounding.
Common Issues and How to Avoid Them
1. Incorrect Gland Size
Using an improperly sized gland can lead to inadequate sealing and a compromised connection.
Solution: Double-check the gland size and match it to the cable diameter using manufacturer specifications.
2. Poor Sealing
A poorly sealed gland can allow water or dust ingress, leading to cable damage.
Solution: Use glands with high IP ratings and follow installation guidelines precisely.
3. Corrosion
Corrosion weakens the gland and may lead to failure in harsh environments.
Solution: Opt for corrosion-resistant materials like stainless steel or aluminum with protective coatings.
