Network Rail Trackside Telecoms Duct 00015
Network Rail Telecommunications Cable
PACW/ solid polyethylene insulation/ PJ filled/ moisture barrier/polyethylene sheathed External Telephone Cable (Complies with Specifications NR/PS/TEL/00015 and TS0886) – Network Rail certificate of acceptance – PA05/06233
External Trackside Telecom Cable Duct Grade
Application
The cable is designed primarily for track-side railway installation in troughing. It is a petroleum jelly filled, twisted pair cable suitable for duct installation with a bonded moisture barrier block polyethylene sheath. It is available for direct buried or open channel installation with an additional protection of a bonded corrugated steel tape and sheath. The additional protection provides protection against rodent attack. The product satisfies the requirements of Network Rail Specification NR/PS/TEL/00015 (formerly GK/RT 0315) and Specifications TS0886 and BR1822 when armoured.
Construction
Twisted pairs in 10 Pair Units. The pair range is 2 – 100.
Product Description
Plain annealed solid copper wire, solid polyethylene insulation, twisted pairs, petroleum jelly filling, water swellable tape, paper core wrap, black polyethylene sheath incorporating a longitudinally applied aluminium/polyethylene moisture barrier.
Insulation Resistance
Insulation resistance measurements shall be made with not less than 500 volts D.C. After steady electrification for one minute the insulation resistance measured between each conductor and the remaining conductors connected together shall be not less than 1500 megohms per 1000 metres at 20°C.
Capacitance Unbalance
Not more than 1% of the corrected capacitance unbalance measurements between adjacent pairs shall exceed the following values: Two-Pair (Quad) Cable 800pF. All other sizes 275pF.
