Understanding Armoured Cable Glands

Armoured cable glands serve as a crucial interface between the cable and the equipment or enclosure it connects to. Their primary function is to provide mechanical protection and wire sealing for armoured cables, which are designed to withstand physical stresses, harsh conditions, and environmental influences.

Factors to Consider in Your Selection

1. Type of Armoured Cable

Different armoured cables require specific glands. Generally, there are two primary types:

• Steel-Wire Armoured (SWA): This type features a protective layer made from steel wires, providing enhanced protection against physical damage.
• Aluminium-Wire Armoured (AWA): Lighter than SWA, AWA cables still offer significant protection but may not be suitable for all applications.

Always match the gland to the type of armoured cable you’re using to ensure compatibility.

2. Ingress Protection Rating (IP Rating)

The IP rating tells you how well a gland protects against dust and moisture. The higher the IP rating, the better the protection. For outdoor or industrial applications where exposure to the elements is likely, look for glands with ratings of IP66 or above.

3. Material Composition

The materials used can affect the gland's durability and resistance to corrosion:

• Brass: Provides good strength and resistivity against corrosion but may not suit all environments.
• Stainless Steel: While more expensive, stainless steel glands are highly resistant to corrosion and are ideal for challenging applications such as marine or chemical environments.
• Plastic: Lightweight and resistant to certain chemicals, plastic glands may be suitable for indoor applications.

4. Cable Size

It's essential to choose a gland that fits the diameter of your armoured cable correctly. A gland that is too small can compromise the cable’s integrity, while one that is too large may not provide a secure fit. Always refer to the manufacturer's guidelines to get the exact measurement needed.

5. Mounting Style

Consider how you will be mounting the gland. Some common styles include:

• Through-Panel Glands: These are used when the cable needs to pass through a panel or enclosure.
• Non-Metallic Glands: Generally used in areas where electrical conductivity poses a risk, these glands still provide high levels of protection.

6. Certification and Standards

Ensure that the chosen gland meets any required certification or industry standards relevant to your application. Look for certifications like ATEX for explosive environments, which indicates the gland is safe to use in hazardous areas.

Installation Tips

Once you've selected the appropriate armoured cable gland, proper installation is paramount:

• Follow Manufacturer Instructions: Always consult the installation guidelines that come with your gland.
• Use the Right Tools: Ensure you have the necessary tools to create a tight and secure fit.
• Check the Seal: After installation, confirm that the gland creates a complete seal to avoid moisture ingress.

Conclusion

Selecting the right armoured cable gland is fundamental to ensuring the safety and longevity of your electrical installations. By considering factors like the type of cable, ingress protection rating, material composition, and correct sizing, you can make an informed choice.

Remember, investing time in selecting quality components can save you from costly repairs and replacements in the future. If you have questions or need additional support, don’t hesitate to consult with a professional. Your electrical systems deserve nothing less than the best protection!
