Explosion Proof Gland

What Is Explosion Proof Gland

Explosion-proof cable glands are the mechanical cable entry devices attached to the end of electrical cables, securing them to other electrical equipment, such as explosion-proof junction boxes, electrical terminals, and plugs. They are essential for terminating cables in harsh or hazardous areas where sealing and ingress protection is necessary. Additionally, they offer strain relief and protect delicate electrical wiring from corrosion, harmful gases, rust, and water. As you can see, these cable glands must match the environment in which they are used. The harsher the environment, the more robust a cable gland must be, as it can be costly if the wrong cable gland is utilised. They must also be selected according to the explosion protection methods employed.

Explosion-proof cable glands are indispensable across various industries where hazardous environments pose significant risks to personnel and equipment. They can withstand harsh conditions while maintaining safety standards.

Temperature Ratings of Explosion Proof Gland

Cable glands are not allocated a ‘T’ class unlike like other items of hazardous area electrical equipment because they are designed as a component part of a piece of equipment and in themselves cable glands do not produce heat; therefore it is impossible to assess any heating effects. However glands are allocated a “service” temperature, which is the temperature range to which a cable gland may be subjected to in service (if not specified in the certification report this is assumed to be -20ºC / +40ºC) and it is the responsibility of the user, in accordance with the installation codes of practice, to select an appropriate gland.

In some cases it may be possible for a cable gland manufacturer to state that a gland is suitable for a specific ‘T’ class application, i.e. where the glands specified ‘service’ temperature significantly exceeds the limiting temperature of the specified ‘T’ class, but the gland will not be marked with any ‘T’ rating.

In most cases the above assessment is determined and decided by the end user, since ‘T’ classes are allocated on the basis of a maximum possible external surface temperature, whilst in service the gland may see greater internal temperatures, or vastly reduced temperatures, due to factors like positioning, the external ambient and the geometry of the enclosure to which the cable glands are fitted.

How Do I Choose a Explosion Proof Gland

Choosing the right cable gland depends on several factors, such as the application, environment, cable type, and size. Here are some general steps to follow when selecting a cable gland:

Determine the cable type and size
Cable glands come in different sizes and are designed to work with specific types of cables. Measure the diameter of the cable and determine its type (e.g., armoured, unarmoured , braided, etc.)

Identify the application and environment
Consider the location where the cable gland will be installed, including the temperature, humidity, and any potential hazards like chemicals or moisture.

Select the material
Depending on the application and environment, you may need to choose a cable gland made from specific materials, such as plastic, stainless steel, brass, or aluminum.

Choose the sealing method
Cable glands can have different sealing methods, such as compression, explosion-proof, or weather-resistant. Select a gland with a sealing method that meets the needs of your application.

Check for certifications
Depending on the industry or application, you may need to choose a cable gland that meets specific certifications or standards, such as ATEX or IP ratings.

Some cable glands may have additional features, such as strain relief, EMC shielding, or grounding capabilities. Consider these features based on your specific needs.

Selecting the right cable gland requires careful consideration of the application, cable type, environment, and sealing requirements. Be sure to consult with a qualified professional if you are unsure about which cable gland is right for your application.

Explosion-proof cable glands are an essential component of electrical systems in hazardous areas. They play a critical role in preventing explosions and fires, and they ensure the safety and reliability of the electrical connections.

Training to Install Explosion Proof Gland

The process of installing the gland depends on the type of explosion-proof cable you are using. However, the basics are generally the same. So you can use what we have shared as a template. However, before starting, please ensure that the installation is carried out by a qualified professional with relevant experience and knowledge.

Installation of explosion-proof gland
Before starting the installation process, make sure that all electrical equipment and power cords are turned off and disconnected. We also recommend checking the cable tube to make sure it is the correct size and compatible with your cables.

In addition, follow the manufacturer’s instructions and ensure that you always follow workplace safety practices. If you work in a dusty environment or have solvents and chemicals in your workplace, you need to properly maintain your cable glands to avoid exposure to these substances. Finally, be careful not to damage the loose input wires.

Installation of gland cable
Now that you’re ready to start, open the explosion-proof cable and remove the nut. To get the right length for the pipe size, you need the right tool to strip the outer sheath of the cable. Don’t forget to expose the internal metal armor if there is any.

Installation of gland cable
After completing these steps, insert the right end of the gland into the cable before placing the sheath or armor evenly around the gland. After that, re-lubricate the nut and carefully tighten it using a wrench or similar tool to secure the gland.

Please note that some cables have two halves. These are designed to fit on both sides of the enclosure to ensure cable sealing. To install this cable gland, you must drill a hole in the wall of the application before securing each half of the gland.
