Description.
Conductor insulation: special PVC, separation soft tape, tinned copper braid, min. coverage 85%, EMC 89/336/EC. Outer sheath: special PVC.
APPLICATION.
Cables used in explosion risk area “i” (IEC 60079-11 Intrisically Safe) are blue coloured to be always easily identified.
This screen reduces EMI (Electromagnetic Interferences) noises up to 100 kHz caused by power lines and by inductive circuits such as electrovalves, motors, transformers, etc., see paragraph “Signal Transmission Noises” in the section “General Information.”.
Moderate resistance to common oils. Flame resistance grade: CEI 20-22 II and IEC 60332-3A.
Limited resistance to abrasion. Cables for intrinsically safe areas are also available in a nonshielded version: see MN-NK
Mutual Capacitance: wire/wire about 130 nF/km @ 1 kHz; wire/shielding about 185 nF/km. Inductance: about 0,65 mH / km.
Max working voltage: 300 V. Test voltage: 1500V up to 0,25 mm2, 2000 V over.
