There are numerous cable glands for various applications.
How well do you know them?
Let's start off with the non-metallic compression gland.
This is typically made of a polymer or type of plastic. It consists of the gland body and a type of rubber compression piece that clamps an unarmoured cable and provides a means of securing a cable in an enclosure, and a level of ingress protection.
Some of these available on the market simply do not fulfill the requirements.
Then there is the armoured cable gland.
These have a dual purpose. They provide a mechanical clamp on the armour of a cable and also ensure electrical continuity of the cable armour to earth.
When fitted with internal seals, an external ingress protection washer and shroud, they are meant to prevent moisture and dust from gaining access to the enclosure, be it a junction box or motor terminal box.
There are also special purpose cable glands, such as Exd (flameproof) and Exe (increased safety) cable glands, for hazardous locations.
These can be both compression glands for unarmoured cables and armoured cable glands for armoured cables.
Cable armour can also take different forms, such as SWA (steel wire armour) or braided/screened cables.
How well do you know the different types of cables and the correct cable gland to use on a particular cable, in a particular application?
