Preface The Asset Standards Authority (ASA) is an independent unit within Transport for NSW (TfNSW)

and is the network design and standards authority for defined NSW transport assets.

The ASA is responsible for developing engineering governance frameworks to support industry

delivery in the assurance of design, safety, integrity, construction, and commissioning of

transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively

discharges obligations as the authority for various technical, process, and planning matters

across the asset life cycle.

The ASA collaborates with industry using stakeholder engagement activities to assist in

achieving its mission. These activities help align the ASA to broader government expectations of

making it clearer, simpler, and more attractive to do business within the NSW transport industry,

allowing the supply chain to deliver safe, efficient, and competent transport services.

The ASA develops, maintains, controls, and publishes a suite of standards and other

documentation for transport assets of TfNSW. Further, the ASA ensures that these standards

are performance based to create opportunities for innovation and improve access to a broader

competitive supply chain.

This standard supersedes RailCorp standard EP 08 00 00 16 SP Designations of Overhead

Wiring Conductor Systems, version 2.1.

The changes to previous content include the following:

• updates to reflect organisational changes and resulting changes in responsibilities

• minor amendments and clarification to content

• conversion of the standard to ASA numbering, format, and style

1. Introduction Overhead wiring (OHW) is used to transmit power from traction substations to electric trains.

OHW generally consists of catenary and contact wires. The contact wire provides a

mechanically continuous path for train pantographs, and the catenary wire is used to support

the contact wire. The traction current to the trains is carried by both the catenary and contact

wires.

2. Purpose The purpose of this document is to list all overhead wiring conductor systems that have been

used in the RailCorp network and to provide a consistent shorthand designation for each

conductor configuration.

2.1. Scope The scope of this document is for 1500 V dc overhead wiring conductor systems as used in the

RailCorp network.

For new installations, all conductors shall be in accordance with T HR EL 08004 ST Overhead

Wiring Fittings and Materials. Contact wires shall also comply with EP 08 00 00 24 SP Contact

Wire.

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

Overhead Wiring Conductor System Selection.

2.2. Application This document provides a detailed description of each overhead wiring conductor system that

has been assigned a Technical Maintenance Code (TMC).

This document is not to be used as a reference for the actual overhead wiring conductor system

installed at a particular location.

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 with approval

by the Lead Electrical Engineer, ASA on a case-by-case basis. See EP 08 00 00 24 SP Contact

Wire for further information on contact wire requirements.

8. Regulated systems – simple catenary This section describes systems comprising of catenary and contact wires in which the wires are

attached to anchor points via a tension regulation device on at least one end.

All regulated tension configurations are considered suitable for speeds up to 130 km/h unless
