    Telecommunications Substation Communications Cabinets Architecture

    Design Work Instruction August 2013

  • SUMMARY Network Standard NS208 defines the architecture, design, procurement and installation of the Ausgrid communications rack and communications equipment for use within the Ausgrid substations. This document is one of a family of documents which encompass NS208.

    ISSUE For issue to all Ausgrid and Accredited Service Providers staff involved with the design of Ausgrids major substations.

    Ausgrid maintains a copy of this and other Network Standards together with updates and amendments on www.ausgrid.com.au.

    Where this standard is issued as a controlled document replacing an earlier edition, remove and destroy the superseded document.

    DISCLAIMER

    As Ausgrids standards are subject to ongoing review, the information contained in this document may be amended by Ausgrid at any time.

    It is possible that conflict may exist between standard documents. In this event, the most recent standard shall prevail.

    This document has been developed using information available from field and other sources and is suitable for most situations encountered in Ausgrid. Particular conditions, projects or localities may require special or different practices. It is the responsibility of the local manager, supervisor, assured quality contractor and the individuals involved to ensure that a safe system of work is employed and that statutory requirements are met.

    Ausgrid disclaims any and all liability to any person or persons for any procedure, process or any other thing done or not done, as a result of this Standard.

    Note that compliance with this Network Standard does not automatically satisfy the requirements of a Designer Safety Report. The designer must comply with the provisions of the WHS Regulation 2011 (NSW - Part 6.2 Duties of designer of structure and person who commissions construction work) which requires the designer to provide a written safety report to the person who commissioned the design. This report must be provided to Ausgrid in all instances, including where the design was commissioned by or on behalf of a person who proposes to connect premises to Ausgrids network, and will form part of the Designer Safety Report which must also be presented to Ausgrid. Further information is provided in Network Standard (NS) 212 Integrated Support Requirements for Ausgrid Network Assets.

    INTERPRETATION

    In the event that any user of this Standard considers that any of its provisions is uncertain, ambiguous or otherwise in need of interpretation, the user should request Ausgrid to clarify the provision. Ausgrids interpretation shall then apply as though it was included in the Standard, and is final and binding. No correspondence will be entered into with any person disputing the meaning of the provision published in the Standard or the accuracy of Ausgrids interpretation.
