The aerial bundled cables designed for overhead distribution lines have all conductors made of aluminium 1350 and insulated with XLPE. Phase and neutral cores are laid up in a bundle with a left hand lay. Can be used for fixed installation as overhead power lines up to 1000 V incl.
BS 7870-5:1999
| Conductor (for either phase, neutral or street lighting) | The conductors shall be of aluminium 1350 wires and are compacted circular stranded(RM). |
|---|---|
| Insulation | XLPE. 1, 2 and 3 raised longitudinal ribs on the surface of the cores. The surface of the neutral core should have at least 12 ribs for cross-sections up to 50 mm^2 and a minimum of 16 ribs for cores above 50 mm². In the case of five core bundles the surface of the protective core should be smooth. |
| Assembly | 2 up to 4 cores of equal cross section are stranded together in left-hand lay, additionally 1 or 2 cores of reduced cross section can be co-stranded. |
