In hazardous environments where flammable gases, vapors, or dust may be present, safety is paramount. Electrical installations in such areas must meet strict regulatory standards to prevent ignition sources. One of the most critical components in this context is the explosion proof cable gland—and ensuring correct explosion proof cable gland installation is essential for compliance and safety.
Understanding Hazardous Zones: Zone 1 Zone 2
Zone 1: An area where explosive atmospheres are likely to occur during normal operations.
Zone 2: An area where explosive atmospheres are less likely but may occur infrequently and only for short durations.
In both zones, electrical equipment must be installed with components that prevent any potential source of ignition. This includes certified cable glands that can withstand internal explosions and prevent their spread.
What Is an Explosion Proof Cable Gland?
An explosion proof cable gland is a specialized fitting designed to connect electrical cables to enclosures while maintaining the integrity of the explosion protection. These glands seal the cable entry points and provide:
Flameproof barriers
Strain relief
Environmental protection (IP66/IP68)
Compliance with ATEX and IECEx standards
These glands are mandatory for installations in areas where there is a risk of explosion due to gas or dust.
Key Steps for Proper Installation
Explosion proof cable gland installation must follow strict guidelines to maintain the flameproof integrity of the system:
Select the Right Gland: Ensure the gland is rated for the specific zone (1 or 2) and certified by ATEX, IECEx, or other relevant authorities.
Prepare the Cable Properly: Strip the cable as per the manufacturer’s guidelines, ensuring there’s no damage to the conductors or insulation.
Follow Manufacturer’s Instructions: Use the correct tightening torque and sequence for seals, armor clamps, and entry threads.
Verify Sealing and Earthing: The inner and outer seals must be secure, and metal glands must ensure continuous grounding.
Inspection and Testing: Once installed, glands should be visually inspected and tested to confirm compliance with hazardous area standards.
Incorrect installation can nullify the explosion-proof rating and introduce significant risk.
