Introduction

Installing a brass cable gland correctly ensures electrical safety, system reliability, and long-term durability. Even a high-quality brass gland can fail if installed improperly. At Volt Metal Industries, we manufacture and export only brass cable glands, brass cable lugs, and earth tags. With decades of field experience, we educate customers and exporters on how to achieve safe, secure, and professional installations.

Why Correct Installation Matters

Every electrical system depends on the connection between the cable and its equipment. A properly installed brass cable gland:

• Maintains mechanical support and electrical continuity.
• Prevents dust, moisture, and chemical ingress.
• Protects cables from pull-out and vibration.
• Ensures proper earthing and strain relief.

Incorrect installation can cause insulation damage, short circuits, or equipment failure. Following best practices helps installers, engineers, and exporters deliver consistent quality every time.

Step-by-Step Brass Cable Gland Installation Process

1. Select the Correct Gland Type

Choose the correct gland based on your cable type—armoured or unarmoured—and environmental conditions. For example:

• Use single compression glands for indoor or general industrial use.
• Use double compression glands for outdoor, armoured, or high-vibration areas.

Since Volt Metal Industries manufactures brass glands only, you ensure superior strength, conductivity, and corrosion resistance compared to plastic alternatives.

2. Measure the Cable Diameter Accurately

Measure the cable’s outer sheath and armour (if any). Match these dimensions to the gland’s entry and clamping size. A tight and accurate fit maintains sealing integrity and strain relief.

3. Prepare the Cable Entry Point

Cut the cable neatly and remove just enough sheath to expose the conductor and armour. Clean the entry area to remove dust or moisture before fitting the gland.

4. Fit the Gland Components in Correct Order

Slide the gland components – nut, washer, seal, and body – onto the cable in proper sequence. Always follow the recommended assembly drawing. Align the gland perfectly with the cable axis before tightening.

5. Tighten Using Correct Torque

Tighten each gland component using a torque wrench. Apply uniform pressure to achieve a firm but not excessive grip. Proper torque ensures sealing without damaging the brass threads or seals.

6. Terminate and Earth Properly

For armoured cables, clamp the armour securely between the gland cone and body. Attach the brass earth tag to maintain a safe earth path. Volt Metal Industries also supplies brass earth tags compatible with all major gland types.

7. Inspect and Test the Installation

After tightening, inspect the gland visually. Check that seals sit evenly, threads engage fully, and there is no gap between fittings. Conduct an electrical continuity test to confirm earthing and mechanical security.

Common Installation Mistakes to Avoid

Installers often face issues that can be easily prevented:

• Selecting the wrong gland size for the cable.
• Over-tightening or under-tightening the gland.
• Ignoring sealing washers or missing O-rings.
• Using plastic or mixed-material glands in high-temperature or outdoor conditions.
• Failing to terminate armour correctly in armoured cables.

Avoiding these mistakes ensures long service life and compliance with international safety standards.

Tips for Exporters and International Projects

Volt Metal Industries exports brass cable glands, lugs, and earth tags to multiple global markets. Exporters can ensure successful overseas installations by:

• Requesting correct thread types (Metric, NPT, PG, or BSP).
• Selecting appropriate plating – nickel or tin – for marine or corrosive environments.
• Following the packing and labelling guidelines for export consignments.
• Providing installers with the manufacturer’s assembly instructions.

By educating end users, exporters help ensure safe and repeatable installations worldwide.

Maintenance and Periodic Checks

Brass glands rarely fail if installed correctly, but inspection helps maintain reliability:

• Re-check the tightening torque after a few operating cycles.
• Inspect seals and threads for corrosion or wear.
• Replace damaged components immediately with genuine brass parts.

Regular checks keep connections safe and stable for years.

FAQ

Q1. Why should I choose brass over plastic glands?
Brass provides superior strength, conductivity, and resistance to corrosion and temperature, making it ideal for industrial and export applications.

Q2. Can I reuse a brass cable gland?
You can reuse it if all parts remain undamaged, but always replace worn seals and washers for safety.

Q3. Do you provide custom sizes or plating?
Yes. Volt Metal Industries manufactures custom brass glands and accessories with options for nickel or tin plating.

Q4. What torque should I use for tightening?
Torque varies by gland size. Always follow the recommended torque chart or contact our technical team for guidance.

Conclusion

Correct installation of a brass cable gland improves system safety, performance, and durability. Every step—from gland selection to tightening – plays an important role. Volt Metal Industries guides customers, distributors, and exporters to install brass cable glands confidently and efficiently.
