Fitting a gland on a cable is essential to ensure the safety, reliability, and longevity of electrical installations. A Cable gland secures the cable’s entry into equipment or enclosures, providing strain relief, environmental sealing, and protection against hazards such as moisture, dust, and mechanical stress. Without a properly fitted gland, cables are vulnerable to damage, which can lead to electrical failures, short circuits, fires, and non-compliance with industry regulations.

What Is a Gland on a Cable?
A Cable gland is a mechanical device designed to attach and secure the end of an electrical cable to equipment or an enclosure. It provides:
- Strain relief to prevent cable movement and wear
- Sealing to block the ingress of moisture, dust, and contaminants
- Mechanical support for stable, reliable connections
Cable glands are made from materials such as brass, stainless steel, plastic, or aluminum, and are available in various sizes and designs to suit different environments and cable types.
Key Reasons to Fit a Gland on a Cable
1. Mechanical Stress Relief
- Prevents cables from being pulled out, twisted, or damaged at the entry point.
- Reduces wear and tear caused by vibration or movement, especially in industrial or outdoor settings.
2. Environmental Protection
- Seals the cable entry, preventing moisture, dust, dirt, and chemicals from entering enclosures and damaging sensitive equipment.
- Ensures continued performance even in harsh or hazardous environments.
3. Electrical Safety
- Minimizes the risk of short circuits, electrical fires, and accidental disconnections by holding cables securely in place.
- Prevents exposed wires and maintains the integrity of the electrical system.
4. Regulatory Compliance
- Helps meet industry safety standards and electrical codes by ensuring proper cable termination and sealing.
- Essential for certifications in regulated sectors such as oil & gas, manufacturing, and infrastructure.
5. Explosion and Corrosion Protection
- Specialized glands prevent the ingress of flammable gases in hazardous areas, reducing the risk.
- Protects cables from corrosion in chemical or marine environments, extending their lifespan.
Types of Cable Glands and Their Applications
| Type | Material | Typical Application | Key Benefit |
| Brass | Metal (Brass) | Industrial, outdoor, hazardous environments | High durability, corrosion resistance |
| Stainless Steel | Metal (Steel) | Marine, food processing, chemical industries | Superior corrosion resistance |
| Plastic/Polyamide | Plastic | Indoor, light-duty, telecom | Lightweight, cost-effective |
| Explosion-Proof | Metal/Composite | Oil & gas, mining, hazardous locations | Prevents gas/flame ingress |
How to Select and Fit a Cable Gland
Step-by-Step Guide (HowTo Schema)
- Identify Cable Type and Size
- Measure the cable’s diameter and check insulation type.
- Choose the Appropriate Gland
- Match the gland material and type to the environment (e.g., brass for industrial, plastic for indoor).
- Prepare the Cable
- Strip the cable as required, ensuring no damage to insulation or conductors.
- Insert the Cable into the Gland
- Slide the gland components onto the cable before termination.
- Secure the Gland
- Tighten the gland to the enclosure and compress the seal around the cable.
- Check the Seal and Strain Relief
- Ensure the gland is tight and the cable is firmly held without movement.
Practical Checklist for Cable Gland Installation
- Measure cable diameter and select a matching gland
- Choose a gland material suitable for the environment
- Inspect the cable and gland for damage before installation
- Ensure proper sealing and strain relief after fitting
- Verify compliance with relevant safety standards

FAQ
Q1: Can I skip fitting a gland if the cable is indoors?
No. Even indoor environments can expose cables to dust, accidental pulls, or moisture. Glands are recommended for all critical electrical terminations.
Q2: Are all cable glands waterproof?
Not all. Check the IP rating of the gland—IP66/IP68 glands offer high water resistance for outdoor or wet environments.
Q3: What happens if a cable gland is not used?
Cables may become loose, exposed to damage, or allow contaminants inside enclosures, leading to failures or hazards.
Q4: How do I know which gland size to use?
Refer to the cable’s outer diameter and match it to the gland’s clamping range, as specified by the manufacturer.
Q5: Can cable glands be reused?
Some types can be reused if undamaged, but always inspect for wear and replace if necessary to ensure safety.
