Cable ComponentsTHIS MANUAL CONTAINS TECHNICAL INFORMATIONON A WIDE VARIETY OF COMMONLY USED MEDIUMVOLTAGE (MV) POWER CABLES MANUFACTURED TOAUSTRALIAN STANDARD AS/NZS 1429.1.Full constructional and technical details are given forPrysmian’s standard range of MV power cables. Otherconstructions and variants are available by special order.For standard industrial applications, XLPE insulation isnormally recommended, but for situations where thecable may be continuously subject to wet conditions,the well proven resistance of Prysmian’s EPR compoundoffers additional security. Both insulation systems havebeen assessed for long term resistance to water underthe two year UNIPEDE test regime and successfully metthe criteria. Prysmian’s EPR compound has also met therequirements of more onerous long term tests.The standard oversheaths supplied are either BLACKPVC (5V-90) or a combination of layers of PVC and HDPEto AS/NZS 1429.1, AS/NZS 4026 and AS/NZS 3808.For situations where limiting the emission of smokeand corrosive gases from cables affected by fire isdesirable, the use of Prysmian’s LSOH HFS-90TP sheathto AS/NZS 3808 is recommended. These cables areconstructionally and dimensionally the same as AS/NZS1429.1 cables and employ the same insulation systemsbut with LSOH sheaths. The tabulated data in thistechnical manual is valid irrespective of the sheathingoption.High-density polyethylene sheath (HDPE) can besupplied where greater impermeability to moisture andgreater resistance to abrasion is required for adverseinstallation conditions, but such sheaths are notrecommended in areas of fire risk.Where protection against termites and other invasiveinsects is required, cables can be supplied with acovering of Nylon 12, or with two helically applied brassor stainless steel tapes. Alternatively Prysmian offerTermitex covering as a protection against termites.For protection against rodents, Prysmian recommendthe use of armour or steel tapes. Brass or coppertapes provide only limited protection against rodentsand specifiers need to be aware of the risk for eachinstallation.4
