Ultimate Guide to Explosion Proof Cable Gland: Benefits, and Types

In industries where safety is a top priority, especially in environments where flammable gases, vapors, or dust are present, ensuring that electrical installations are protected from potential hazards is crucial. This is where Explosion Proof Cable Gland come into play. These devices are vital in preventing explosions from occurring in hazardous environments by safely sealing electrical cables, ensuring that they are properly grounded, and providing a secure, airtight connection.

This blog will serve as an ultimate guide to understanding what explosion proof cable glands are, their installation process, and why choosing the right one is essential for your electrical setups. We’ll also introduce Cabex India, a trusted name in the industry, known for manufacturing high-quality explosion proof cable glands that meet stringent safety standards.

What Are Explosion Proof Cable Glands?

An explosion proof cable gland is a type of device designed to connect and seal the ends of electrical cables while preventing any sparks or flames from escaping into hazardous areas. These glands are typically used in industries such as oil and gas, chemical plants, mining, and other sectors where flammable materials are handled.

Their primary function is to maintain the integrity of electrical equipment, ensuring that the equipment operates safely without the risk of igniting surrounding flammable substances. Explosion proof cable glands work by containing any potential explosion within the equipment, preventing it from reaching the external hazardous environment.

Why Are Explosion Proof Cable Glands Important?

Hazardous areas are categorized based on the type and level of explosive risks present. Explosion proof cable glands are specifically designed for environments where there is a high risk of explosions. Installing them ensures the safety of both the equipment and the personnel working in these dangerous settings.

Here’s why explosion proof cable glands are so essential:

• Preventing Ignition: They prevent sparks or flames from escaping through cable entries, which could ignite surrounding gases or dust.
• Ensuring Sealed Connections: These glands offer robust sealing, ensuring that the connection remains airtight and dustproof, protecting the electrical components from external contaminants.
• Compliance with Safety Standards: They are built to meet various international safety standards, such as ATEX, IECEx, and others, ensuring their suitability for hazardous zones.

Explosion Proof Cable Gland Installation

The installation of explosion proof cable glands is critical, as improper installation can compromise safety. When installing an explosion proof cable gland, it’s essential to follow specific steps to ensure that the equipment operates safely and effectively. Below is a step-by-step guide for installing explosion proof cable glands:

1. Identify the Hazardous Zone: Before installation, it’s essential to determine the hazardous zone classification. This will dictate the type of explosion proof cable gland required. For example, Zone 1 and Zone 2 classifications will require different specifications.

2. Choose the Correct Gland Size: The size of the cable gland must match the diameter of the cable to ensure a proper fit. This is essential for maintaining a tight, secure seal.

3. Prepare the Cable: Strip the outer sheath of the cable without damaging the inner wires. Ensure that the cable is clean and free of any dirt or debris that could interfere with the sealing process.

4. Insert the Cable into the Gland: Carefully insert the cable into the gland body, ensuring that it’s properly seated. The cable should extend through the gland body so that the inner conductors are fully protected.

5. Tighten the Compression Nut: Tighten the compression nut on the gland body to secure the cable in place. This step is crucial for creating an airtight seal around the cable, preventing the ingress of gases or dust.

6. Check the Sealing: Once the gland is installed, inspect the connection to ensure that it’s fully sealed. Any gaps or loose connections could compromise the integrity of the installation.

7. Test for Continuity: After installation, it’s important to perform a continuity test to ensure that the electrical connection is intact and that there’s proper grounding. This step ensures the gland is functioning correctly and the system is safe.

By following these steps, you can ensure a safe and reliable explosion proof cable gland installation. Always adhere to the manufacturer’s instructions and relevant industry standards during the process.

Choosing the Right Explosion Proof Cable Gland

When selecting an explosion proof cable gland, there are several factors to consider to ensure that you choose the right one for your specific application:

• Material: Cable glands are available in various materials, including brass, stainless steel, and aluminum. The material you choose should be compatible with the environment and the type of cable being used.

• Thread Type: The thread type of the gland should match the equipment it’s being installed into. Common thread types include metric, NPT, and PG.

• Certification: Always ensure that the explosion proof cable gland you choose has the necessary certifications for your hazardous zone, such as ATEX or IECEx.

• Cable Type: The gland should be compatible with the type of cable you’re using, whether it’s armored or non-armored, to provide the proper level of protection.

• Temperature Range: Consider the operating temperature of your environment, as different cable glands have different temperature ratings.
