What are Steel Wire Armoured cable glands? In short, installers of SWA cable use cable glands to seal and terminate Steel Wire Armoured cable into an enclosure or electrical box. The gland maintains a weather and dustproof seal preventing dust and moisture from entering the box and also seals and protects the cables outer sheath. SWA Cable glands also prevent the likelihood of a cable detachment or pull out in the event the cable is twisted or pulled.
Main functions:
- Protection from the environment – seals the cable’s outer sheath to prevent dust, particles and moisture from the electrical box or enclosure.
- Earth continuity – if the cable gland is metallic in construction, it can be tested for earth continuity.
- Securing the cable – provides resistance against cable pull-outs when the cable is impacted.
- Complex sealing – cable glands offer substantial ingress protection for the part of the cable that enters electrical boxes or enclosures.
