EX glands
EX glands must be properly certified and properly sized for operation in explosive areas. Requirements specified in the installation code or standard and any certification restrictions or described in the conditions of use must be considered. EX glands must also be approved for the selected cable type and suitable for the specific application, expected ambient temperatures, local climate, environmental exposure and any other adverse conditions.
More detailed information on the intricacy of applications in explosive atmospheres can be found in relevant knowledge bases and standards.
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.

Ex cable glands as key components of electrical systems in hazardous areas
Cable glands are mechanical cable insertion devices that can be made of metallic materials, non-metallic materials or combinations thereof. They are used in all industries in connection with cables and cabling used in electrical, instrumentation, control and automation systems.
Ex cable glands can be used for all types of cables: power, control, instrumentation, data and telecommunications. They serve as sealing and termination devices to ensure that the properties of the enclosure into which the cable enters are safely preserved.
Main functions of cable glands according to type
- Environmental protection: the glands seal the outer sheath of the cable, protecting it from dust and moisture in the electrical or instrumentation enclosure.
- Grounding continuity: for reinforced cables, chokes with metal construction allow grounding continuity. In this case, the chokes can be tested to withstand the minimum short-circuit current corresponding to the reinforcement of the cable or the peak failure of the electrical system.
- Cable holding force: HARDO glands provide adequate resistance to cable pullout by preventing lateral and axial loads from being transferred to the inner ends of the cable conductors.
- Additional sealing: the glands provide additional sealing of the portion of the cable entering the enclosure when high penetration protection is required.
- Environmental sealing: the glands maintain the degree of penetration protection at the level of the enclosure and cable gland combination by selecting the appropriate accessories dedicated to this function.
- Corrosion resistance: the glands are made of corrosion-resistant materials according to the selected technical standard or corrosion resistance tests.
- Explosion protection: the glands maintain an Ex level of protection for the equipment to which they are attached when installed in explosive atmospheres (hazardous areas).
