How to Choose the Right Cable Gland for LED Explosion-proof Light | ATEX & IECEx Guide
When you're setting up LED explosion-proof lighting in hazardous areas, every component matters. But there's one small piece that often gets overlooked until the last minute: the cable gland.
Here's the thing—a cable gland for LED explosion-proof light isn't just a fancy cable holder. It's a critical safety device. In environments where explosive gases, dust, or vapors are present, that humble fitting is what stops an electrical connection from becoming an ignition source. It maintains the integrity of the enclosure, keeps gases and dust out, withstands mechanical stress, and ensures your installation stays compliant with ATEX and IECEx standards.
Without the right hazardous area cable gland, even the best-certified explosion-proof LED light can fail safety requirements.
What Exactly Does an Explosion-proof Cable Gland Do?
An explosion-proof cable gland is a fixing and sealing device used in electrical machinery, marine systems, and corrosion-resistant equipment. Its job is straightforward but essential:
- Flameproof Protection: It ensures that if an explosion happens inside the fixture, the flame and hot gases cannot escape through the cable entry.
- Environmental Sealing: It provides a high IP rating (usually IP66 or IP68) to protect the internal LEDs from moisture, dust, and corrosive chemicals.
- Strain Relief: It clamps the cable firmly, ensuring that vibrations or physical pulling won't damage the internal wiring.

Types of Cable Glands for Hazardous Areas
Choosing the right gland depends on your cable type and installation method. Here are the three most common types we use at ShineLong:
Single-Seal Atex Connector
The single-seal connector is a high-quality standard for non-armored cables. It provides a tight, gas-proof seal around the outer sheath of the cable. These are commonly used in Zone 1 and Zone 2 environments where basic but robust sealing is required.
Double-Seal Armored Atex Connector
If you are using armored power cables—which are standard in many industrial and mining sites—you need a gland that can handle the extra layers. A double-seal connector seals both the inner sheath and the outer sheath of the cable. More importantly, it includes an internal clamping mechanism to ground and secure the cable's armor, ensuring electrical continuity and mechanical strength.
Pipe-Connecting Atex Sealed Connector
In some installations, cables aren't just exposed—they are run through conduits or pipes for extra protection. A pipe-connecting gland allows you to transition seamlessly from the lighting fixture into a pipe system. This gives you the flexibility to route power safely while maintaining full explosion proof certification.
