Construction and Technical Details – 6mm Armoured Cables Guide
Each 6mm SWA armoured cable is manufactured for safe power distribution and long service life:
- Conductor: Plain annealed copper, Class 2 stranded (BS EN 60228)
- Insulation: Cross-linked polyethylene (XLPE Type GP8)
- Armour: Galvanised steel wire armour (SWA)
- Sheath Options: PVC (BS 5467) or LSZH (Low Smoke Zero Halogen, BS 6724)
These cables can be installed clipped direct, laid on tray, buried underground, or embedded in concrete.
For full technical data, see the Doncaster Cables H6943XL6.0 LSNH specification confirming an operating range from −15 °C to +90 °C and a bending radius of 8 × diameter.
PVC vs LSZH Armoured Cables
| Feature | PVC SWA Cable | LSZH SWA Cable |

| Outer Sheath | PVC Type 9 | LSZH Type LTS1 |
