In modern electrical installations, particularly in hazardous environments, ensuring the integrity of cable connections is paramount. Armoured Cable Glands are crucial components designed to secure and protect cables entering electrical equipment while providing mechanical strength and protection against environmental factors. These glands are essential for preventing damage, ensuring the safety of the installation, and maintaining the performance of the system in harsh conditions.

Whether you are dealing with industrial plants, power stations, or offshore platforms, armoured cable glands offer significant advantages. This article delves into the key aspects of armoured cable glands, including their function, benefits, types, and applications, highlighting their critical role in ensuring reliable and safe electrical systems.

An armoured cable gland is a mechanical fitting designed to provide a secure, reliable, and protected connection between an armoured cable and electrical equipment. These glands are used for cables that have an additional layer of metal shielding or armour, providing protection against mechanical damage, abrasion, and environmental stress.

Armoured cables are commonly used in high-risk or heavy-duty environments, where electrical installations need to be safeguarded from physical damage, moisture, or corrosion. The role of the armoured cable gland is to maintain the cable’s structural integrity, provide a safe and effective seal, and prevent any external forces from damaging the cable or compromising its safety.

There are various types of armoured cable glands designed to meet different installation requirements. Each type is engineered to offer specific features that ensure protection against mechanical, electrical, and environmental risks. Below are the most common types of armoured cable glands:

These glands are used for basic cable protection, where the cable armour is exposed to mechanical stress but does not require additional sealing or protection. Standard armoured cable glands offer a simple, cost-effective solution for connecting armoured cables to electrical equipment in low-risk environments.

In environments exposed to moisture or liquids, watertight armoured cable glands provide a crucial seal against water ingress. These glands are equipped with rubber or silicone seals that prevent water, dust, or chemicals from entering the cable system, ensuring the continued performance and reliability of the electrical installation.

In hazardous environments where explosive gases or dust are present, explosion-proof armoured cable glands are used to prevent the risk of ignition. These glands are designed to contain any potential sparks or heat generated by electrical faults and prevent them from igniting the surrounding atmosphere. They comply with stringent international safety standards and are commonly used in oil and gas, petrochemical, and mining industries.

Double compression armoured cable glands offer enhanced protection by compressing both the outer sheath of the cable and the armour. This provides additional mechanical strength, ensuring that the cable is firmly secured and protected from external forces. These glands are ideal for use in environments where cables are exposed to high levels of mechanical stress.

Some armoured cable glands are designed to maintain earth continuity between the armour of the cable and the electrical system. These glands are used in installations that require a direct connection between the cable’s armour and the grounding system. They help to prevent electric shock hazards and ensure the safety of the installation.

The versatility and robustness of armoured cable glands make them suitable for a wide range of applications across various industries:

In manufacturing plants where heavy machinery and electrical systems are in constant use, armoured cable glands provide the necessary protection to ensure the safety and reliability of the electrical installations. These glands prevent mechanical damage and protect cables from abrasion, reducing downtime and ensuring continuous operations.

In offshore platforms and marine environments, cables are exposed to harsh conditions, including saltwater, moisture, and corrosive elements. Armoured cable glands offer robust protection against these environmental factors, ensuring the cables remain secure and functional.

The oil and gas industry is fraught with hazards, including the presence of flammable gases and corrosive materials. Armoured cable glands are used extensively in this industry to ensure the safe installation of cables and prevent sparks or damage that could lead to explosions.

In power stations, electrical cables are subject to constant mechanical stress and environmental challenges. Armoured cable glands protect cables from physical damage and ensure the safety of the power generation process by preventing electrical faults and ensuring reliable cable connections.

In the chemical and pharmaceutical sectors, the risk of contamination and damage to electrical systems is high. Armoured cable glands help protect cables from moisture, chemicals, and other environmental factors, ensuring safe and reliable electrical systems in these critical industries.

Armoured cable glands are indispensable components in modern electrical installations, providing essential protection against mechanical damage, moisture, and environmental stress. Their role in safeguarding electrical systems cannot be overstated, especially in hazardous or high-risk environments where safety is paramount. With various types designed for different applications, armoured cable glands ensure the integrity, longevity, and safety of electrical installations in diverse industries.
