Construction and testing according standards

NetworkRail NR/L2/ELP/27408

BS EN 60228 BS 7655-1.3 and BS 7655-4.2

IEC IEC 60502-1

Rated Voltage

(1)

0,6/1kV

Outer sheath colour

BLACK

Conductor Identification

Brown, Black

Marking on the outer sheath

On the outer sheath by embossing on two primary

lines with the following information (example) : Legend 1 (line 1):

CABELTE ELECTRIC CABLE 600/1000 V

NR/L2/ELP/27408 PVC 2x50 Al 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 Al 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 marking

and the beginning of the next identical element of marking

is ≤ 550mm.

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

insulation thickness permits an insulation level suitable for

voltages 1000/1730V (Uo/U).

SAC/XLPE/FGT/PVC

Circular conductors schematic design

Shaped conductors schematic design

1 – Conductor Solid Aluminium Conductors (SAC), circular

(≤ 35mm2) or shaped (> 35mm2), class 1, 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 tape

Polypropylene 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 minimum

overlap of 15%. Weaving design: plain weave 1/1

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

Optional tape - Polypropylene plastic tape applied

under the fiber glass tape, helically with overlap.

Nominal thickness of the tape =0,05mm

6 – Outer sheath

PVC type 9 according to BS 7655-4.2.

7 – Fillers

PVC.
