To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Australia web site at .au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue.Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization.We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Please address your comments to the Chief Executive of either Standards Australia International or Standards New Zealand at the address shown on the back cover.This Standard was issued in draft form for comment as DR 98043.AS/NZS 4026:2001Licensed to UEA Electrical Pty Ltd on 06 Mar 2007. 1 user personal user licence only.

The Standard applies to a range of cables recommended for use by electricity distributors in underground residential distribution (URD) systems at working voltages of 0.6/1 (1.2) kV, 6.35/11 (12) kV and12.7/22 (24) kV.For reasons of standardization and rationalization, this Standard provides for the construction, dimensions and test requirements of only a limited range of cables.The requirements of this Standard are compatible with and complementary to those for the range of cables covered in AS/NZS 1429.1, AS 1026 and AS/NZS 5000.1.This Standard differs from the previous edition in the following significant ways:(a)This Standard has been published as a Joint Australian/New Zealand Standard.(b)For 6.35/11 (12) kV distribution network cables an additional 300 mm2 conductor size has been included in the rationalized range.(c)The terms light duty and heavy duty in reference to metallic screens for cables complying with AS/NZS 1429.1 have been replaced by nominal short circuit ratings of 3 kA and 10 kA respectively.(d)For XLPE insulated 0.6/1 (1.2) kV distribution cables, separate rationalized ranges of conductor sizes have been included for Australia and New Zealand.(e)For XLPE insulated 0.6/1 (1.2) kV service cables, an additional 50 mm2 conductor size has been included in the rationalized range.(f)An additional high voltage Type Test on the XLPE insulated cores of the0.6/1 (1.2) kV service cables has been introduced.(g)Additional maximum continuous current rating data has been included to provide for installation at different soil temperatures.The term informative has been used in this Standard to define the application of the appendix to which it applies. An informative appendix is only for information and guidance.3CONTENTSAS/NZS 4026:2001Licensed to UEA Electrical Pty Ltd on 06 Mar 2007. 1 user personal user licence only.
