How Armoured Cable Glands Enhance Electrical Safety and Durability?

Electrical safety and durability are two key factors in the design and installation of industrial, commercial, and residential wiring systems. Armoured cable glands are one of the key components that ensure the safety and longevity of electrical systems. Armoured cable glands provide strong protection for cables, especially in harsh environments, to prevent physical damage, moisture, and other potential hazards.

In this blog post, we will explore what armored cable glands are, what types there are, their benefits, and factors to consider when selecting and installing them.

What is an Armoured Cable Gland?

An armoured cable gland is a device used to securely attach and seal the ends of armoured cables to electrical equipment, panels, or enclosures. These glands are designed to provide both mechanical support and environmental protection for cables, ensuring a safe and durable connection. Armoured cables are often used in environments where extra protection is required due to physical hazards, moisture, or extreme temperatures.

The armoured component of the cable typically consists of a metal sheath, which can be made of steel or aluminum, providing the cable with added strength and resistance against impact, abrasion, and corrosion. The cable gland, in turn, serves as the interface between the cable and the equipment, offering a seal that prevents dust, water, or other contaminants from entering the cable or electrical system.

Types of Armoured Cable Glands

There are several types of armoured cable glands, each designed for different applications. The key difference between them lies in how they grip and seal the armoured cable, as well as the environmental conditions they are built to withstand.

Here are some common types:

Benefits of Using Armoured Cable Glands

Armoured cable glands provide several advantages that contribute to the overall safety, durability, and performance of electrical installations.

Here are some of the key benefits:

Enhanced Mechanical Protection: Armoured cables are designed to withstand external forces, such as impact, abrasion, and crushing. The cable gland ensures that the armoured sheath is securely connected to the equipment, preventing accidental damage and minimizing the risk of short circuits or cable failures.

Environmental Protection: One of the primary functions of armoured cable glands is to seal the cable entry points and protect the internal components from dust, moisture, and other contaminants. This is especially important in outdoor or harsh environments, such as factories, construction sites, or marine applications.

Prevention of Cable Pull-Out: A properly installed armoured cable gland will help prevent the cable from being accidentally pulled out of the equipment, reducing the risk of cable damage or electrical faults. This ensures the integrity of the system and minimizes downtime caused by cable failures.

Earthing and Grounding: Armoured cable glands often incorporate an earthing or grounding function. By providing a secure connection to the earth, they help prevent electrical shocks and reduce the risk of electrical fires caused by faulty wiring.

Increased Durability and Longevity: Armoured cable glands are built to last, offering long-term protection for cables and electrical systems. Their ability to resist environmental factors such as corrosion, vibration, and extreme temperatures makes them ideal for industrial and outdoor applications where reliability is critical.

Importance in Industrial Applications

In industrial applications, where heavy machinery and equipment are used, maintaining the integrity of electrical wiring is crucial to ensure efficient and safe operation. Armoured cables and glands provide the extra protection necessary to withstand harsh environments, such as mechanical stress, chemicals, moisture, and extreme temperatures. These factors often pose significant risks to electrical systems, but armoured cable glands offer superior protection, ensuring that cables remain intact and operational, even in challenging conditions.

Moreover, armoured cable glands play a vital role in ensuring safety compliance in industries such as oil and gas, mining, and manufacturing, where strict safety regulations are required to prevent electrical hazards. By minimizing the risk of electrical failures caused by cable damage or inadequate protection, these glands contribute to a safer working environment. Additionally, their use can reduce the likelihood of system downtime and cable failures, ultimately saving on repair, replacement, and maintenance costs, while enhancing the overall longevity and efficiency of electrical systems.

Factors to Consider When Choosing Armoured Cable Glands

Choosing the right armoured cable gland for your application requires careful consideration of several factors.

Here are some key points to keep in mind:

A. Cable Size and Type
Ensure that the gland is compatible with the size and type of the armoured cable. The gland should fit securely around the cable to provide the necessary protection.

B. Material
Choose a gland material that suits the environment. For instance, stainless steel is ideal for corrosive environments, while brass is suitable for general applications.

C. Environmental Conditions
Consider the environment in which the cable will be used. If the cable will be exposed to chemicals, moisture, or extreme temperatures, select a gland that offers adequate protection against these elements.

D. Safety Standards
Make sure the gland meets industry-specific safety standards, particularly for hazardous environments where explosion-proof or fire-resistant features are required.

E. Ease of Installation
Opt for a gland that is easy to install and maintain, reducing installation time and improving system efficiency.

Armoured Cable Gland Installation Tips

Proper installation of armoured cable glands is essential to ensure their effectiveness and reliability.

Here are some installation tips:

Clean the Cable: Before installing the gland, clean the cable to remove any dirt, moisture, or corrosion. This ensures a secure and tight connection.

Strip the Cable: Carefully strip the outer sheath of the cable, exposing the armoured layer. Avoid damaging the cable conductors.

Install the Gland: Slide the gland onto the cable, ensuring that the armour is clamped securely inside the gland. Tighten the gland to prevent any movement or pull-out.

Check the Seal: After installation, check that the gland is properly sealed to prevent any contaminants from entering the system. This is especially important for outdoor or industrial applications.

Test the Connection: Finally, test the connection to ensure that the gland is securely attached and that the cable is functioning correctly.
