EX gland

An EX gland is a dedicated mechanical device for inserting cables into electrical and instrument housings in explosive atmospheres. It is a key element to ensure safety in industrial installations operating in explosive atmospheres (in the presence of flammable gases, dusts or vapors).

Design and materials

ATEX glands can be made of various materials, including metals (stainless steel, nickel-plated brass) and corrosion-resistant plastics. The choice of material depends on the environmental conditions in which the gland will operate. In explosive atmospheres, it is necessary for glands to be corrosion-resistant and to withstand extreme temperatures and other adverse conditions.

Cable Glands for Armoured Cables

HCG2 series of cable glands for armoured cables is available in a variety of sizes ranging from M16 to M90 and thread types including metric and NPT. They are an excellent option for enteering cables into enclosures, cable strain relief, sealing enclosures and assisting in dust, moisture and water protection, as well as for industrial applications where there is significant contamination by water, vibration or extreme temperatures.

Cable Glands for Non-armoured Cables

ATEX gland features

  • Environmental protection: seals the outer sheath of the cable, providing protection from dust and moisture, which is key to maintaining the characteristics of the electrical enclosure
  • Grounding continuity: for reinforced cables, metal glands provide ground continuity, which is important for installation safety. They can be tested to withstand minimum short-circuit current.
  • Mechanical resistance: provides adequate cable holding force to prevent cable pulling out and prevent loads from being transferred to internal cable terminations.
  • Additional sealing: when a high level of ingress protection is required, HARDO glands offer additional sealing, maintaining an appropriate IP rating.
  • Maintaining Ex protection level: in explosive atmospheres, glands must maintain the Ex protection level of the equipment to which they are attached, according to ATEX and IECEx standards.

    • Selection according to certification

    ATEX glands must be certified in accordance with relevant safety standards (e.g. IEC 60079-14). It is important that they are properly selected for the cable type, installation specifications and environmental conditions. Certification ensures that the gland meets all explosion protection requirements, which is crucial for the safety of installations in hazardous areas.

    Application in industry

    ATEX glands are indispensable in many industries, such as chemicals, petrochemicals, pharmaceuticals, and mining. They provide critical protection in environments where there is a risk of explosion, protecting both personnel and equipment from potential hazards.

    ATEX glands are an indispensable component of electrical systems in hazardous areas. Thanks to their design, corrosion-resistant materials and compliance with international safety standards, they ensure the reliability and durability of installations in the most demanding conditions. Choosing the right ATEX gland is crucial to ensuring the safety and efficiency of electrical systems in harsh and hazardous environments.
