Not covered here? Send your drawing — an engineer replies within 2 business hours.

What governing standard and construction define SNE (BS 7870-3.20 SNE 0.6/1 kV Separate Neutral & Earth Split-Concentric Service Cable)?

SNE (BS 7870-3.20 SNE 0.6/1 kV Separate Neutral & Earth Split-Concentric Service Cable) is manufactured in accordance with BS 7870-3.20 / BS 7671 for 0.6/1 kV service over -25 °C to +90 °C. Its 4-layer construction comprises stranded copper conductor, xlpe core insulation, polymeric neutral covering, pvc outer sheath.

What is the minimum bending radius and installation temperature for SNE?

The minimum installed bending radius for SNE 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 SNE arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per BS 7870-3.20 / BS 7671); (02) XLPE core insulation (Extruded XLPE dielectric (individual core / group layer)); (03) Polymeric neutral covering (Extruded Polymeric neutral covering protective layer (individual core / group layer)); (04) PVC outer sheath (Extruded PVC outer sheath protective layer (continuous layer)).

What factory test certificates are supplied with SNE?

Every production drum or spool of SNE undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per BS 7870-3.20 / BS 7671, and is delivered with an EN 10204 3.1 factory test certificate.
