CSEP Instruments Cable Flame Retardant (Non-Armoured)
CU/XLPE/OSCR/PVC-FR 300/500V Ref to BSEN 50228-7, IEC 60332-3-24

Application

Instrumentation cables are used in data processing and process control. The electrostatic screen protect the screened pairs against outer electrostatic interference fields. Low level of line attenuations and low  mutual capacitances enable long transmission distances fast pulse acceleration.


Cable Structure & Features

Conductor	(Cu) Plain annealed stranded copper conductor Class 2, IEC 60228, BS6360
Insulation	(XLPE) Cross-linked Polyethylene
Pairing / Twining	Two/Three/Four insulated cores are cabled together
Assembly	Multiple pairs/triads/quads are cabled together, supplied with non-hygroscopic filler (optional) to obtain a circular construction and covered with a polyester tape wrapping
Overall Screen	(OSCR), Min. 20% overlap of aluminium backed polyester tape in contact with 0.5mm² (16/0.20mm) tinned annealed drain wire followed by a polyester tape wrapped over the screening tape
Outer Sheath	(PVC-FR) PVC compound with Flame redartant. Black (Optional: Blue colour for Intrinsically Safe)
Insulation color	1 pair in Black & White 2 pair & above -each pair in Black & White core with numbering. 1 triad in Black, White & Red 2 triad & a bove –each triad in Black, White & Red printed with   numbering.
