1 Introduction This document sets out the approved overhead wiring conductor systems and provides a consistent shorthand designation for each conductor configuration.

Note: The designations and corresponding descriptions listed in this document must not be amended as they represent actual installed configurations. However, this document is not to be used as a reference for the actual overhead wiring conductor system installed at a particular location. The status of a system may be amended. New systems and designations may be appended as approved.

It complies with the requirements of the RailCorp Safety Management System at the time of issue.

2 Scope and application For convenience, the overhead wiring conductor systems described in this document may be referenced by the system and number, eg. “System 2”, as a short hand configuration description.

All conductors shall be in accordance with EP 08 00 00 13 SP. Contact wires shall be in accordance with EP 08 00 00 24 SP.

For information on the process of selecting a suitable OHW System, refer to EP 08 00 00 17 SP.

The configurations listed in this document are to be referenced by any other electrification documents.

4 Definitions Current An OHW conductor system approved for use for the electrification of new routes, and for the major rehabilitation of existing infrastructure. See EP 08 00 00 01 SP.

Not For Future Construction (NFC) The OHW configuration may remain in service where already installed. This configuration is not to be used for future construction. If a Waiver is approved the configuration may be used for extensions and alterations to equipment of the same configuration.

Obsolete OHW of this configuration is not to be used for future construction and any existing OHW should be programmed for renewal.

Presag The process of deliberately lowering the contact wire (below the straight line between the contact wire registration points at consecutive support locations) towards mid-bay in a regulated overhead wiring system.

Technical Maintenance Code (TMC) A unique code allocated to an item of equipment or component that is repairable and/or has a defined maintenance policy. For overhead wiring equipment the TMC begins with “EP” (Electric Power), followed by “08” (for Overhead Wiring), then a six digit number which uniquely defines the equipment.

T/ω The quotient of the nominal catenary tension (T) in Newtons divided by the nominal system weight (ω) in N/m. Units are metres.

The current form of documenting OHW System details is to show them on the relevant OHW Layout, at the Sydney-end anchor of the conductor run, using the following format:

Conductor = Size (mm²) / Tension (kN) / Standard Height (m)

Example: (for OHW System 2) …

CATY = 270 / 30.0 / 6.5

CONT = 2x137 / 2x12.5 / 5.0

6 Contact wire material The existing RailCorp network has contact wires that are of hard drawn copper, tin bearing copper or cadmium copper.

Tin bearing copper contact wire shall be used for all current and future projects. Hard drawn copper contact wire may be used as an alternative for regulated overhead wiring and with approval by the RailCorp Chief Engineer Electrical on a case by case basis only. See EP 08 00 00 24 SP.

7 Regulated systems – Simple catenary This section describes systems comprising catenary and contact wires in which the wires are attached to anchor points via a tension regulation device at least at one end. All regulated tension configurations are considered suitable for speeds up to 130km/h unless stated otherwise.
