Do you have to gland both ends of SWA?

Glands should always be fitted at both ends to correctly terminate the cable into the enclosure, if the armour isnt being used as the cpc then an earth banjo at the supplly end will do.

Can you gland SWA into a plastic box?

You can terminate into a plastic enclosure as long as you use a ‘banjo’ tag and connect that tag to the earth terminal. It is also recomended that you use 2 lock nuts(either side of the plastic) to avoid ‘creepage’ of the plastic! Hope this helps.

How do I choose a cable gland size?

Cable gland size is equal to the size of the cable bundle diameter. For example, if your cable bundle diameter is 50mm means then you should select the 50MM cable gland only.

Can you use SWA as CPC?

Armouring: Steel Wire Armour (SWA) used for mechanical protection. That way the cable can withstand higher stresses, be buried directly and used in external or underground projects. The armouring is usually connected to earth and can be used as the CPC (as described above).

Does SWA armor have to be earthed?

As to why it needs to be earthed, that’s because it is an exposed-conductive-part and by definition is not normally live but can become live under fault conditions. It has nothing to do with the type of earthing or whether TT rods are being used, that’s a separate earthing issue. SWA armour must be earthed.

Do you have to use banjo on SWA?

Now there aren’t many cases when you’ll have that many sockets side by side, if its not high leakage stuff after all, but if instead something more like theatre lamps, then mechanical strength trumps all, so proper SWA gland, but no need to banjo or tail.

How do you connect armored cable to CU?

SWA should be terminated in to a brass gland. If you want to use a plastic CU then you can terminate the SWA in to a single metal socket box using a metal blanking plate. You can then use a short length of corrugated plastic conduit to protect the inner sleeve of the cable going into the CU.

What is the difference between BW and CW cable glands?

The BW gland is used for indoor application when a waterproof seal is not required. CW Gland – Brass gland for use with steel wire armoured cables (H694-XL). Used to provide clamping of the armour wire to ensure electrical continuity and mechanical retention of the cable.

Do you need to earth both ends of SWA Cable?

It should be earthed at least at the source end, as it is clearly an exposed conductive part. Most calculation methodologies and much tabulated cable data assumes that the armour is reliably connected to earth at both ends.

Which gland packs are available for SY Cable?

When do I need to consider alternative Cable glands?

*If the cable armour is of a non-standard material, e.g. Aluminium Wire Armour, it may be necessary to consider an alternative Cable Gland material, e.g. Aluminium. **For certain medium voltage and high voltage cables, with higher fault rate levels, CIEL Cable Glands, which have been tested for higher SCC faults may be required.
