33KV Power Cables to BS 7835 NR/PS/ELP/00008
Application
33KV Power Cables are used to distribute three phase a.c. electrical power supplies at nominal system
voltages of 33KV to traction substations on D.C. electrifi ed lines.
Construction
Conductors： Class 1 circular solid aluminium (for 185 mm²) or class 2 compact circular stranded plain copper (for
300mm²) to BS EN 60228: 2005 (previously BS 6360).
Conductor Screen： Extruded semi-conducting XLPE (Cross-Linked Polyethylene) solidly bonded.
Insulation： XLPE (Cross-Linked Polyethylene).
Insulation Screen： Extruded semi-conducting XLPE (Cross-Linked Polyethylene), solidly bonded and cold
strippable.
Separator： Semi conducting water blocking tape.
Screen： Copper wire screen, helically wound with equalising copper tape.
Separator： Semi conducting water blocking tape.
Sheath： Graphite coated MDPE type TS2.
