Cable Glands for Armoured Cable: A Complete Guide for Safe Connections

When it comes to electrical wiring – the terms safety and reliability are inextricably linked. In India, where heavy machinery, high voltage setups, and industrial environments tend to dominate, armoured cables are often employed for protection against physical damage. However, using armoured cables is not enough in itself. Added in conjunction are cable glands, which are also important to create safe, strong, and long-lasting connections.

Though cable glands are generally small, they can have a large role towards ensuring safety, organisation, and efficiency in an electrical system. Below is everything you need to know about cable glands for armoured cables, why they matter, and how to determine which are correct for your needs.

What is a Cable Gland?

Cable glands are small, mechanical devices that secure the end of a cable to a piece of equipment to ensure that connections remain safe and reliable. You could think of cable glands as a physical lock that holds the cable in place, often protecting the cable from moisture, dust, and vibration – all of which are common challenges in Indian conditions. Cable glands also ensure that proper earthing and grounding occurs in order to avoid electrical faults and promote safety. With armoured cables, standard cable glands should not be employed as these cables have extra layers of protection with metals. There are brass slots that have been specifically designed to accommodate their strength and maintain a strong seal, in addition to preventing conductivity. There is a cable gland specific to every situation, whether for industrial or commercial uses or for residential applications. Cable glands can also protect copper terminals and electrical connections for consistent future performance.

Why do Armoured Cables Need Cable Glands?

Armoured cables are considered stronger than standard cables because they have extra protection - a layer of metal. Armoured cables are also appropriate for use in industrial or outdoor applications because they can withstand being crushed or snagged during transportation, installation, or use. However, most of the time, their armoured shells need to be properly terminated to avoid the risk of short circuits, overheating, or loose connections.
This is where cable glands for armoured cables step in:

  • This is where armored cable glands come into play:
  • Safety: By providing adequate earthing, they guard against electrical shocks.
  • Durability: They shield cables from deterioration, particularly in India's harsh climate of heat, dust, and rain.
  • Efficiency: Smoother current flow and reduced energy loss are the results of secure connections.
  • Compliance: Appropriate termination using cable glands is required by numerous industrial standards in India.

Types of Cable Glands for Armoured Cables

While there are many varieties, the most common types include:

  • Brass Indoor Cable Glands – Ideal for dry indoor environments.
  • Brass Outdoor Cable Glands – Designed to withstand moisture, dust, and weather.
  • Flameproof Cable Glands – Used in industries like oil, gas, and chemicals where safety is critical.

Each type is chosen based on the installation environment and safety requirements.

How to Install a Cable Gland on Armoured Cable

Installing a gland may sound technical, but it follows a simple process:

  • Strip the Cable – Remove the outer sheath carefully to expose the armour.
  • Fit the Gland – Insert the gland components in the right order.
  • Secure the Armour – Clamp the armour wires into the gland to ensure proper grounding.
  • Tighten the Fittings – Use the locknut and tighten the gland securely.
  • Check the Seal – Make sure the gland grips the cable firmly to avoid slippage.

(Pro tip: Always disconnect power before working on electrical terminations.)

Choosing the Right Cable Gland

Here’s what to keep in mind when selecting a cable gland for armoured cables:

  • Cable size – Pick a gland that matches your cable diameter.
  • Application area – Indoor, outdoor, or hazardous zones.
  • Material – Brass is the most durable and widely used in India.
  • Standards – Ensure it meets IS/IEC safety standards.
