Product Information
Full details
The Event Distribution SWA Steel Wire Armoured 3 Core Cable is a high-durability solution designed for electrical professionals and DIYers requiring reliable outdoor power distribution. Featuring a robust steel wire armour layer, it offers excellent mechanical protection against external damage, making it ideal for underground installations or heavy-duty outdoor environments; however, the rigid nature of the armouring can make it challenging to route through tight bends or cramped conduit spaces.

FAQs
Can I use this cable for indoor wiring?
Yes, it can be used indoors, though its mechanical strength is generally unnecessary and its rigidity may make installation more difficult than standard twin-and-earth cable.
Does this cable require conduit for underground burial?
Because of the steel wire armouring, it is specifically designed to be buried directly in the ground, provided it is at a safe depth and marked correctly.
What tools are needed to terminate the cable?
You will need a cable cutter capable of cutting SWA, a sharp utility knife for insulation stripping, and appropriate SWA cable glands and spanners.
Is this cable UV resistant?
Yes, the outer black sheath is typically formulated to be resistant to UV degradation for long-term outdoor exposure.
What is the maximum current this cable can carry?
The current carrying capacity depends on the cross-sectional area (mm²) of the conductors and the method of installation. Always consult the IET Wiring Regulations (BS 7671) for specific rating tables.
Troubleshooting
Difficulty stripping the outer sheath and armour
Use a professional SWA cable stripping tool or a junior hacksaw to carefully score the armour layer without nicking the inner cores.
Water ingress at connection points
Verify that high-quality, weather-rated SWA glands are installed correctly and that the shroud is fully seated.
Pros and Cons
Pros
- High mechanical resistance due to steel armour
- Wide temperature operating range
- Reliable performance for high-voltage outdoor use
- Durable XLPE insulation protects against thermal degradation
Cons
- Increased cable weight due to steel armouring
- Less flexible than unarmoured cables
- Requires specialized tools for cutting and stripping
Setup, Compatibility & Care
Installation of SWA cable requires the use of appropriate SWA-rated cable glands to ensure the armour is properly terminated and the seal remains weatherproof. It is recommended to use specialized cable cutters designed to handle the steel wire layer. Always ensure that the cable is secured with heavy-duty cleats if running along walls to account for the weight of the armour. For underground burial, ensure the trench is of an appropriate depth and clearly marked with warning tape. Regularly inspect the gland terminations for signs of moisture ingress or loose connections to maintain the cable's longevity and safety profile.
