Questions engineers ask first

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

What governing standard and construction define CNE (BS 7870-3.10 CNE 0.6/1 kV Combined Neutral & Earth Concentric Service Cable)?

CNE (BS 7870-3.10 CNE 0.6/1 kV Combined Neutral & Earth Concentric Service Cable) is manufactured in accordance with BS 7870-3.10 / ENA TS 09-7 for 0.6/1 kV service over -25 °C to +90 °C. Its 4-layer construction comprises stranded copper conductor, xlpe phase insulation, concentric copper neutral-earth, pvc outer sheath.

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

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

From inside to outside, the construction sequence is: (01) Stranded copper conductor (High-conductivity copper conductor per BS 7870-3.10 / ENA TS 09-7); (02) XLPE phase insulation (Extruded XLPE phase insulation dielectric (continuous layer)); (03) Concentric copper neutral-earth (Concentric copper neutral-earth metallic electromagnetic screen (helically applied wires)); (04) PVC outer sheath (Extruded PVC outer sheath protective layer (continuous layer)).

What factory test certificates are supplied with CNE?

Every production drum or spool of CNE undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per BS 7870-3.10 / ENA TS 09-7, and is delivered with an EN 10204 3.1 factory test certificate.
