Marking on the outer sheath

On the outer sheath by embossing on two primarylines with the following information (example) :

Legend 1 (line 1):

CABELTE ELECTRIC CABLE 600/1000 V

NR/L2/ELP/27408 PVC 2x50 Cu YEAR H NMR

“Railway Catalogue number” Property of Network Rail M.M.

Legend 2 (line 2):

CABELTE ELECTRIC CABLE 600/1000 V

NR/L2/ELP/27408 PVC 2x50 Cu YEAR H NMR

“Railway Catalogue number” Property of Network Rail

Year - Year of manufacture

M.M. - Metric Marking (shall be printed)

Line 1 and line 2 are spaced ~180º.The distance between the end of one element of markingand the beginning of the next identical element of markingis ≤ 550mm.

(1) - Whilst the rated voltage is 600/1000V, the reinforced

insulation thickness permits an insulation level suitable for

voltages 1000/1730V (Uo/U).

Circular conductors schematic design

Shaped conductors schematic design

1 – ConductorStranded copper conductor s, circular (≤ 16mm

2) or

shaped (> 16mm2), class 2, according to

BS EN 60228.

2 – Insulation

XLPE type GP 8 according to BS 7655-1.3.The two insulated conductors are stranded.

3 – Bedding (only in circular conductors design)

PVC.

4 – Identification tapePolypropylene tape with a printed legend: “Property of Network Rail CABELTE YEAR”, applied over the

stranded cores.Thickness = 50µm | Minimum width = 5mm.

5 – Rodent protection

Fibreglass tape, helically applied with a minimumoverlap of 15%. Weaving design: plain weave 1/1

(272 tex). Nominal thickness of tape = 0,65mm.

Optional tape - Polypropylene plastic tape appliedunder the fiber glass tape, helically with overlap.

Nominal thickness of the tape =0,05mm
