BS 6724 XLPE-SWA-LSZH (BS 6724 0.6/1 kV Cu/XLPE/LSZH/SWA/LSZH Low-Smoke Zero-Halogen Armoured Cable) is manufactured in accordance with BS 6724 / IEC 60502-1 for 0.6/1 kV – 1.9/3.3 kV service over -25 °C to +90 °C. Its 5-layer construction comprises stranded copper conductor, xlpe core insulation, non-hygroscopic bedding, galvanized steel wire armour, lszh outer sheath.

What is the minimum bending radius and installation temperature for BS 6724 XLPE-SWA-LSZH?

The minimum installed bending radius for BS 6724 XLPE-SWA-LSZH is 8 × OD across its continuous operating temperature range of -25 °C to +90 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of BS 6724 XLPE-SWA-LSZH arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per BS 6724 / IEC 60502-1); (02) XLPE core insulation (Extruded XLPE dielectric (individual core / group layer)); (03) Non-hygroscopic bedding (Extruded Non-hygroscopic bedding protective layer (continuous layer)); (04) Galvanized steel wire armour (Galvanized steel wire armour mechanical protection (helically applied wires)); (05) LSZH outer sheath (Extruded LSZH outer sheath protective layer (continuous layer)).

What factory test certificates are supplied with BS 6724 XLPE-SWA-LSZH?

Every production drum or spool of BS 6724 XLPE-SWA-LSZH undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per BS 6724 / IEC 60502-1, and is delivered with an EN 10204 3.1 factory test certificate.
