Introduction
The Doncaster Cables SWA Armoured Cable guide explains how steel wire armoured (SWA) cable supports safe outdoor and underground wiring. It highlights mechanical protection, correct selection, and installation practices under BS 7671 Wiring Regulations*. For product selection, browse our Armoured Cable Range and related Doncaster Cables Products (anchor text varied to avoid exact‑match).
Why Installers Choose SWA
- Steel wire armour delivers genuine impact protection.
- Suitable for direct burial when installed to good practice.
- Weather, UV and moisture resistant for long service life.
- Broad size and core options for domestic, commercial and industrial work.
Compare sizes in our SWA Cable Options, or filter by Low‑Smoke SWA, LSF SWA, PVC‑Sheathed SWA, and SWA by the Metre.
Choosing Core Counts & LSZH Variants
Pick cores to suit the application and protection scheme:
- 3‑core armoured cable – common for single‑phase (L, N, CPC).
- 4‑core SWA – lighting/control or three‑phase without neutral.
- 5‑core SWA – three‑phase with neutral/control.
For reduced smoke and halogen‑free requirements, see 2‑core LSZH SWA, 3‑core LSZH SWA, 4‑core LSZH SWA, 5‑core LSZH SWA, and 7‑core LSZH SWA.
Alternatives to SWA (and When)
Where flexibility is more important than armour, consider Hi‑Tuff Cable (no steel armour). For European specifications and direct burial without armour, see NYY‑J Cable Options. For a deeper comparison, read our Hi‑Tuff Cable Guide.

FAQs – Doncaster Cables SWA Armoured Cable guide
Can SWA be buried directly?
Yes—when installed to good practice and BS 7671 guidance (depth, marking, and mechanical protection where necessary).
Is Hi‑Tuff equivalent to SWA?
No. Hi‑Tuff is tough but not armoured; it’s chosen for flexibility and easier handling.
Which glands should I use?
Select SWA termination kits that are correctly sized for the cable you’re working with. Always include earthing banjos to maintain continuity of the armour and ensure a safe, compliant installation.
How do I keep outdoor joints weatherproof?
Choose high-quality IP-rated enclosures and make sure all cable entries are properly sealed. Pay attention to routing so water cannot pool around joints, reducing the risk of long-term damage.
