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 LS0H 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 LS0H 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 ~180.
The distance between the end of one element of marking
and the beginning of the next identical element of marking
is 550mm.
SAC/XLPE/FGT/LS0H
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 Identification tape Polypropylene tape with a printed legend:
Property of Network Rail CABELTE YEAR, applied over the stranded cores.
Thickness = 50m | Minimum width = 5mm.
4 Bedding (only in circular conductors design) LS0H compound.
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.
6 Outer sheath LS0H type LTS4 according to BS 7655-6.1.
