    RT/ZHLS, A-2Y(L)2Y External Telephone Cables to NR/PS/TEL/00015

    • RT/ZHLS, A-2Y(L)2Y External Telephone Cables to NR/PS/TEL/00015
    • RT/ZHLS, A-2Y(L)2Y External Telephone Cables to NR/PS/TEL/00015
    • RT/ZHLS, A-2Y(L)2Y External Telephone Cables to NR/PS/TEL/00015

    Application

    The cables are designed primarily for trackside railway installation in non electrifi ed area. For direct burial application, brass tape armoured or Zetabon type corrugated steel tape armoured can be offered against rodent attack.

    Standard

    • NR/PS/TEL/00015 (formerly RT/E/PS/00015 or GK/RT 0315)
    • TS0886/BR1822
    • BR892

    Cable Construction

    • OptionalConductors: Solid plain copper conductor, 0.63 or 0.9 mm nominal diameter.
    • Insulation: Solid polyethylene to BS 6234.
    • Cabling Element: Two insulated conductors are twisted together to form a pair.
    • Stranding: Pairs are helically stranded in 10 pair units.
    • Core Wrapping: Plastic tape(s) with overlapping.
    • Moisture Barrier: One laminated sheath made of aluminium tape (0.15mm) coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
    • Outer Sheath: Polyethylene to BS 6234. LSZH compound option can be offered upon request.
    • Jelly Filled Cables: The cable core interstices are fi lled with petroleum jelly to avoid longitudinal water penetration within the cable. The water resistant filling compound is applied to the air space between non-hygroscopic tape and shield, shield and sheath within the cable core.
    • Armoured Cables: Corrugated steel tape armour coated on both sides with copolymer can be applied over an intermediate sheath. The steel tape thickness is 0.145mm. Brass tape armour can be offered as an option.
