What is EMC cable gland?
Electromagnetic Compatibility, also known as EMC, is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment.
The goal of EMC is the correct operation of different equipment in a common electromagnetic environment.
That’s why the EMC cable gland is important in the shielding concept of a system.
The EMC cable gland means the cable gland with electromagnetic compatibility.
The EMC cable gland not only can like other cable glands can provide ideal strain relief function and attach electrical cables to equipment securely.
But also can make sure that external signals cannot upset the normal operation of circuits, and the operation of that circuit does not affect other circuits.
How do EMC cable glands work?
When the isolation cable enters the EMC cable gland, the metal contact piece attached to the cable gland can be used to make contact with the metal isolation woven mesh inside the cable. In turn, the electromagnetic waves of the interference are guided to the ground line, so that the electromagnetic interference source can be evacuated.
How to install a EMC cable gland?
To correct installation of the EMC cable gland is very important, only the correct installation can play its role.
Step 1:
Screw the lock nut, then tighten the full EMC cable gland to the housing, install the lock nut in the back side to fit the EMC cable gland and enclosure
Step 2:
Determine the spot where the cable will enter the enclosure and mark the jacket. Remove the outer sheath of shielded cable, it will need approx 5-10mm of the insulation of the cable.
Step 3:
Insert cable through EMC cable gland, make sure the EMC cable gland’s grounding springs are in contact with the shield of the cable. The design of the contact elements will adapt to different cable diameters according to the clamping range of the cable glands.
Step 4:
Tighten the cap and conductivity will be established. Once the gland is secured, do not pull or rotate the cable because this could damage the cable.
EMC cable gland as an economic benefits solution, are widely used in electrical, automotive and Communications Engineering.
Jixiang EMC cable glands are made of nickel plated brass and fast assembly. The thread type could be PG type, metric type and NPT type as customers need, , more information about EMC cable gland, feel free to contact us today.

Before you using an armoured cable gland, noted to ask yourself these questions:
Select the correct type of Armoured Cable Gland, consider:
Type and size of the armour braid
Is the armoured cable gland be situated in a safe or hazardous zone
Is the pressure rating of the armoured cable gland size you’ve picked high enough for your application needs?
Other factors to consider are if the surrounding area is damp, dusty or any gases or corrosive materials around
Select the correct size of Armoured Cable Gland, consider:
Diameter of cable inner bedding
Diameter of cable lead covering
Is the armoured cable gland size wire hole diameter large enough to accommodate all the cables in the specific system?
Is the armoured cable gland size mounting hold diameter large enough for your cable gland?
Is the armoured cable gland size and depth thread metric or PG?
After selecting the suitable Armoured Cable Gland, you can start the installation.
How to Fit an Armoured Cable Gland?
Get these tools ready: a pair of quality wire cutters or a hacksaw, suitably sized spanners
And switch off all electrical equipment and disconnect any live wires.
The fitting process is as follows:
Step 1. Unscrewing the armoured cable gland
Unscrewing each parts of the armoured cable gland in the correct order, convenient for later use
Step 2. Fit the PVC shroud
The PVC shroud is used to provide a cover for the armoured cable gland for aesthetic and protection reasons. Cut the end off the protective cover and slide this onto the wire, make sure it is facing the correct way!
Step 3. Remove the protective sheath of the cable
Simply slice this with a suitable knife, remove the protective sheath, the length depends on the type of the armoured cable gland you’re using, you can find the steel wires sticking out.
Step 4. Strip the armouring layers
You use a hacksaw you can lightly score the steel wire and then bend it back and forth to break it off. Regarding the thin SWA cable, you can use side cutters.
Step 5. Fit the outer seal nut, body and anyway clamping ring
Screw the outer seal nut and body together, slide the SWA cable through them and anyway clamp the ring.
Step 6. Fit the armoured clamping cone
Fit the cone of the cable gland between the inner insulation and armouring. The steel wires need flaring slightly. Make sure these lay over the cone and do not enter it as this can cause damage to the inner insulation.
Step 7. Use your spanners to tighten each gland part
Slide up the Anyway Clamping Ring, screw the body back to the cone, thereby forcing the anyway clamping ring up the cone and trapping the wires in place
Step 8. Tighten the lock nut
Seal the back of the armoured cable gland by applying the lock nut. These compress the internal sealing against the outer insulation, making the armoured cable gland watertight.
Slide the PVC shroud over the gland and you have successfully terminated a wire at an appliance/ box.
Conclusion
This is your step-by-step guide on how to install armored cable glands. These are only the essential information you need to know about armoured cable glands.

Hazardous Area Classification
The Explosion-proof Cable Gland are an essential part of the wide range of electrical explosion protection equipment and prevent the occurrence of sparks or arcs which could lead to an explosion.
Firstly, we need to know three necessary components for an explosion to occur:
1.Flammable Substance– this needs to be present in a relatively high quantity to produce an explosive mixture (e.g. gas, vapours, mists and dusts).
2.Oxygen – oxygen is required in high quantities and in combination with the flammable substance to produce an explosive atmosphere.
3.Ignition Source– a spark or high heat must also be present.
Fundamentally, for an explosion to take place, flammable or explosive gases, vapours, mists or dusts will be present. Then, the level of risk of an explosion is based on the frequency and duration of the occurrence of an explosive atmosphere.
Hazardous areas are classified into zones based on an assessment of the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:
Within Europe ATEX certification of Explosion-proof Cable Gland for use in potentially hazardous atmospheres is compulsory.
Jixiang’s Explosion-proof Cable Gland available in different materials as per the need such as brass, stainless steel and nickel plated brass.
