What governing standard and construction define EISF (NF M 87-202 EISF Individual & Overall Screened Unarmoured PVC Instrument Cable)?

EISF (NF M 87-202 EISF Individual & Overall Screened Unarmoured PVC Instrument Cable) is manufactured in accordance with NF M 87-202 / IEC 60332-3 for 500 V service over -30 °C to +70 °C. Its 7-layer construction comprises stranded bare & tinned copper conductor, al/pet individual screen, pvc individual sheath, pvc core insulation, polyester binder, al/pet overall screen, pvc rh outer sheath.

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

The minimum installed bending radius for EISF is 7.5 × OD across its continuous operating temperature range of -30 °C to +70 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of EISF arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Stranded bare & tinned copper conductor (High-conductivity bare & tinned copper conductor per NF M 87-202 / IEC 60332-3); (02) Al/PET individual screen (Al/PET individual screen metallic electromagnetic screen (individual core / group layer)); (03) PVC individual sheath (Extruded PVC individual sheath protective layer (individual core / group layer)); (04) PVC core insulation (Extruded PVC dielectric (individual core / group layer)); (05) Polyester binder (Helically applied polyester binder); (06) Al/PET overall screen (Al/PET overall screen metallic electromagnetic screen (lapped tape)); (07) PVC RH outer sheath (Extruded PVC RH outer sheath protective layer (continuous layer)).

What factory test certificates are supplied with EISF?

Every production drum or spool of EISF undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per NF M 87-202 / IEC 60332-3, and is delivered with an EN 10204 3.1 factory test certificate.
