Hazardous Area Cable Glands – Ensuring Safety

Hazardous area cable glands are widely used in industries where explosive or flammable substances are present. Key applications include:

In industries dealing with hazardous environments, ensuring the safety and reliability of electrical connections is paramount. Hazardous Area Cable Glands serve a crucial role in protecting cables from explosion risks, fire hazards, and environmental factors. These specialized glands are engineered to provide secure sealing, mechanical retention, and environmental protection, making them indispensable in oil and gas, chemical processing, pharmaceutical, mining, and marine industries.

What Are Hazardous Area Cable Glands?

Hazardous area cable glands are specialized connectors designed to terminate cables in potentially explosive atmospheres. These glands prevent flammable gases, vapors, or dust particles from igniting due to electrical sparks or excessive heat. They comply with stringent international safety standards such as ATEX, IECEx, UL, and CSA, ensuring they meet the highest industry requirements.

These glands come in various materials like brass, stainless steel, and aluminum to withstand corrosive environments. They are designed for use with armored and unarmored cables and can be fitted with additional sealing solutions to provide enhanced ingress protection.

Types of Hazardous Area Cable Glands

1. Ex d Flameproof Cable Glands

These are designed for Zone 1 and Zone 2 hazardous locations, where an explosive gas atmosphere is likely to occur. They prevent flame propagation inside the enclosure and eliminate the risk of explosion.

2. Ex e Increased Safety Cable Glands

Used in areas where the presence of explosive gases or dust is minimal but still a concern. These glands provide enhanced mechanical protection and maintain ingress protection to prevent the entry of contaminants.

3. Ex n Restricted Breathing Cable Glands

Designed for Zone 2 environments where explosive gases are not frequently present but could appear under abnormal conditions. These glands limit the ingress of flammable substances and prevent electrical components from becoming an ignition source.

4. Ex i Intrinsically Safe Cable Glands

Used in circuits where electrical energy is limited to safe levels, ensuring that even a faulty connection will not cause an explosion. These are commonly used in low-energy instrumentation and control circuits.

5. EMC Cable Glands

Designed to provide electromagnetic compatibility (EMC) shielding, these glands are essential in environments where electrical interference can affect the performance of sensitive instruments.

Key Features of Hazardous Area Cable Glands

1. Explosion-Proof Design – Prevents internal ignition from escaping and causing a broader explosion.
2. Ingress Protection (IP) Ratings – Offers IP66, IP67, and IP68 ratings for superior protection against water, dust, and corrosive substances.
3. Durable Materials – Available in brass, stainless steel, aluminum, and nickel-plated brass to withstand extreme conditions.
4. Thread Types – Comes in multiple threading options like metric, NPT, BSP, and PG for compatibility with various enclosures.
5. Wide Temperature Range – Can operate in extreme temperatures, ranging from -60°C to +200°C, making them ideal for harsh environments.
6. Multi-Cable Compatibility – Suitable for armored, unarmored, marine, and flexible cables.

Applications of Hazardous Area Cable Glands

Hazardous area cable glands are widely used in industries where explosive or flammable substances are present. Key applications include:

• Oil & Gas Platforms – Offshore and onshore installations require flameproof cable glands for safety in volatile conditions.
• Chemical Processing Plants – Protection against corrosive chemicals and combustible gases.
• Mining & Tunneling – Ensures dust and gas containment in underground operations.
• Pharmaceutical Facilities – Prevents the risk of ignition in sensitive production areas.
• Marine & Offshore – Used in ships, tankers, and floating rigs where exposure to saltwater and humidity demands durable components.
• Power Plants & Refineries – Provides long-term reliability in high-temperature and high-pressure environments.

Choosing the Right Hazardous Area Cable Gland

Selecting the correct cable gland depends on several factors:

• Type of Hazardous Zone – Determine if your application is in Zone 0, Zone 1, or Zone 2 (for gases) or Zone 20, Zone 21, or Zone 22 (for dusts).
• Cable Type – Identify whether you are using armored or unarmored cables.
• Material Requirements – Choose between stainless steel, brass, or aluminum based on the environmental conditions.
• Temperature & IP Rating – Ensure the gland can withstand extreme weather conditions and is compliant with IP66 or higher.
• Certification Compliance – Look for ATEX, IECEx, or UL-certified cable glands for international safety compliance.
