In potentially explosive industrial environments, choosing the right ATEX cable gland is essential to ensure safety and compliance. But what criteria should you take into account to make the right choice? Let’s take a closer look at the technical, regulatory and practical aspects that influence this choice for the safety and performance of industrial installations.
What are the technical characteristics of an ATEX cable gland? ?
An ATEX cable gland has several features, mainly concerning :
- Material : a cable gland can be made of brass, stainless steel or plastic. Each material has its own advantages and disadvantages.
- Size : this must correspond to the diameter of the cable to be fixed. An incorrect size can compromise the safety of the installation.
- Type of cable : round cable, flat cable, armoured cable, etc.
- The level of protection: this must comply with standards to guarantee safe installation in areas at risk of explosion.
By taking these features into account, you can choose the cable gland that best suits your needs.
Which cable gland for which application?
To choose the right cable gland, you first need to define the type of application you’re going to use it for, according to the ATEX classification. Is your application in Zone 1 or 2 (gas), or Zone 21 or 22 (dust)?
- Zone 1 or 2 applications require an ATEX ‘d’ type cable gland. These models are designed to withstand an internal explosion. They prevent the propagation of the explosion outside the enclosure.
- Zone 21 or 22 applications require ATEX type ‘e’ cable glands. They prevent ignition of surrounding dust by arcs, sparks or high temperatures.
The nature of the cable
The presence of armor on the cable is an aspect to be taken into account when choosing a cable gland. The armor, often made of materials such as stainless steel, strengthens the cable and offers additional protection against mechanical damage, such as twisting, crushing or cutting. In harsh industrial environments where cables may be exposed to difficult conditions, armor plays an essential role in ensuring the durability and reliability of electrical connections.
When selecting a cable gland, it is therefore advisable to check whether the cable is fitted with an armor suitable for the environment in which it will be used. This will guarantee optimum protection against mechanical hazards, while ensuring compliance with current safety standards.
Cable gland compatibility with your equipment
Make sure your ATEX cable gland is compatible with your equipment. The wrong choice can lead to safety problems. There are several factors to consider:
- The type of cable you use: some cable glands are only compatible with certain types of cable.
- The material of your equipment: some are not compatible with all cable glands.
- The operating temperature of your equipment: some cable glands cannot withstand all temperatures.
Cable gland reliability and cost before purchase
Before finalizing your cable gland purchase, check its cost and reliability. The cable gland is a safety component, and its failure can entail risks. Make sure your cable gland complies with current standards. A reliable, cost-effective cable gland is a sound investment for your company. Its quality will guarantee the safety of your installations and your employees.
The choice of your ATEX cable gland must be rigorous and based on a number of criteria, including compliance with standards, type of application, cable size and manufacturing material. Don’t hesitate to ask the experts for advice to make the best possible choice. This will ensure the safety and efficiency of your installations.
