LV Aerial Bundled Cable Aluminium conductor Construction

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 mm² 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.
