Introduction

Cable glands are tools which are vital when terminating cables in harsh or hazardous settings.

This is where sealing, ingress protection and why cable gland is earthing is required.

Its role is to safely pass a tube, wire, or cable through an enclosure.

They offer strain relief and are also made to include flames or electrical parts which may take place in hazardous settings.

Are you struggling to find the right resources for your problem?

Fret not, because you’ve come to the perfect place! Allow this post to help you with your concerns. 

But first, keep in mind that armoured cable glands run a set of vital roles, especially in cable management.

How to Install Armoured Cable Gland

In fact, Did you know that they are created to attach and secure the end of an electric cable and the device it is connected to? 

Cable gland offer:

• earthing 
• grounding 
• insulation 
• bonding and;
• strain relief

They also act as a seal, stopping exterior impurities from causing any damage to the electrical system and the cable.

Some of these contaminants are:

• fluids,
• dirt,
• dust

 the following guidelines will help ensure that the installation of cable glands ensures a safe and reliable connection:

1. Care should be taken to avoid damage to entry threads when handling and installing Cable Glands.
2. Do not install cable glands whilst circuits are live. Similarly, following energising of the electrical circuits, Cable Glands should not be dismantled or opened until the circuit has been safely de-energised.
3. Cable gland components are not interchangeable with those of any other Cable Gland manufacturer. Components from one manufacturer’s product cannot be used in that of another, doing so will affect the safety of the installation and invalidate any explosion protection certification.
4. A Cable gland is not a user-serviceable product and under certification protocols, spare parts are not permitted to be supplied for products that have already been put into service.
5. Cable gland sealing rings are included within the cable gland when despatched from the factory. There should be no circumstances where sealing rings need to be removed from the Cable Gland.
6. Care should be taken to avoid exposure of Cable Gland sealing rings to dirt, hostile chemicals/substances e.g. solvents, and other foreign bodies.

Proper Step on Installing Armoured Cable Glands

Step 1: Determine the type of steel in the cable

Check the number of cores available on the cable. 

Make sure you also determine their exact size. 

Step 2: Check the gland pack

Before you start installing your armoured cable gland, make sure you carefully check your gland pack.

Doing so will confirm that what you have is the proper gland for the cable you have chosen.

On the back of the gland pack, you will see a grid matrix. 

That grid matrix presents the size of the conductors.  

There, you will have different sizes, such as 1.5, 2.5, 5, 6, 10, and so much more.

It also goes across and looks at the number of conductors within the actual SWA cable. You need to match that gland to the actual cable you are using. 

The gland pack will be composed of:

• two shrouds 
• two locking nuts
• two gland nuts
• two gland bodies 
• two earthing rings 

That will offer you enough to terminate both ends.

Step 3. Measure the length you need

Before you start the termination process, it would help if you measure the length of the cable you need.

Grab a tape and put a mark on it so you’ll have an idea of the area to cut.

Step 4. Fit the shroud 

Here’s where the real thing begins.

Grab your shroud and insert it onto the end of the SWA cable. Pull it nice and firmly. 

Cut around the top, but make sure the shroud has still a good fit to the SWA cable. 

After cutting, slide it down into the cable.

Step 5: Cut the cable 

Grab a junior hacksaw and cut the cable around the top of the tape you put earlier. 

Just follow the tape line that is there as best as you could. 

Just make sure you don’t go through, as you can damage the conductors inside.

 

Step 6: Remove the PVC

After you got around the cable, pull the outside of the PVC with your knife. 

Hold the armoured cable firmly and run your knife out along the cable length. Then remove it all.

Step 7: Unwind the wire off the cable 

Gently rock the wire backward forward after you unwind the cord off the cable.

You need to break it away from the base. If it doesn’t come off, you can always use your junior hacksaw.

Step 8: Put on the gland nut 

Get your gland nut and make sure the threads in the gland are pointing upwards. 

Determine how much of the PVC you are going to remove to expose the SWA. 

You need to ensure you do not take too much of the PVC off. 

To do that, take a knife and cut a centimetre 10 below the taped section. Just run it around with a knife.

 Step 9. Insert the gland with the serrated edge down 

Make sure the thimble part of the gland will drop inside and does not go beyond the thread.

Wind the gland body and gland nuts open. 

You can then drop the gland underneath the SWA.

Remember that it must be a firm rotation.

Make sure the SWA is in the section which of the thimble or the serrated part of the gland. 

Pull it out from fully inside it. 

Let the nut to come up to meet the threads. You need to make sure they do not cross-thread.

Push the gland downward, so it’s in the armouring. 

Wind it up with your fingers.

Step 10. Tighten it off 

The best way to tighten it is by using a spanner.  

Get two spanners. The first spanner should be on the actual nut while the other one will be on the gland body. 

Try to bring it back up. Twist the gland nut to tighten it into the gland body. 

It’s recommended to use spanners rather than adjustable grips, as the latter shaves off the brass parts of the gland body.

Step 11: Remove the outside PVC on the other side of the cable 

About ten to fifteen millimetres away from the body, the body itself will be attached to the earth.

Therefore, you do not want the conductors to rub against the actual body.

Take your knife and cut gently round.

Give it a little twist and remove it slowly. 

You will then expose the three conductors.

Step 12: Add the earthing ring to the enclosure

The next thing you need to do is to add the earthing ring into your enclosure, followed by the nut on the inside.

 

For the last step, make sure you check that none of the steel wire armours have crossed over.

To do that, simply rotate all the way around and make sure none of them have missed underneath the gland body. 

Now the gland is on and the gland is tight.

Conclusion

Cable glands are made for use with either non-armored or armored cable.

If used with armored cable, they offer ground earth for the cable design.

A compression ring or O-ring sealing element can tighten around the diameter of the cable.

It seals any risky flames, sparks or currents from coming to the machinery to which the cable leads.

They could be made of an array of plastics and metals, depending on their application.

These could be:

• aluminum
• brass
• plastic or
• stainless steel

Because they are made with safety in mind, it’s vital that cable glands bring one or more of the following electrical safety specification ratings.

Some of these are:

• IECx
• ATEX
• CEC
• NEC
• or likewise depending on the nation of origin as well as use

So if you want to get your cable glands, it is crucial that you size them appropriately.

That’s because only one cable can be utilized with one gland.

And the seal should be made with included o-ring.

Not with other elements the user might introduce like tape.

 

You will find a lot of glands accessible at different manufacturing outlets.

You can look a bit online and create a list of local dealers or manufacturers to receive the best offer.
