AERIAL (ABC)Aerial Bundled Cables (ABC) are overhead power lines that combine several insulated conductorsbundled tightly together, usually with a bare neutral conductor. This contrasts with the traditionalpractice of using uninsulated conductors separated by air gaps.

Given that tree growth is a significant problem for overhead power lines. Aerial bundled cableswill not arc over if touched by tree branches. Although persistent rubbing is still a problem, tree-trimming costs can be reduced.

All cables are manufactured in accredited ISO9001 factories to A/NZ Standards.

OPGWOptical Ground Wire (OPGW) is a type of cable manufactured from steel and aluminium strandswhich encompass a tubular structure containing optic fibre cables. The OPGW cable is runbetween the tops of high-voltage electricity pylons. The conductive part of the cable serves tobond adjacent towers to earth ground, and shields the high voltage conductors from lightningstrikes.

The optic fibres within the cable are generally single mode optic fibres with low transmission loss.These can be utilised for communication networks between cities, and for carrying data. Thenumber of optic fibres within the cable is varied according to project requirements.

Aerial Bundle Cable (ABC) is a very innovativeconcept for overhead power distribution. Itprovides higher level of safety and reliability,lower power losses and ultimate systemeconomy by reducing installation,maintenance and operative cost. This systemis ideal for rural distribution and it isespecially perfect for installation in difficultterrains such as hilly areas, forest areas,coastal areas etc. ABC is also considered to beideal for power distribution in congestedurban areas with narrow lanes and by-lanes.In developing urban complex, ABC cable is thefirst choice because of it’s flexibility forre-routing as demanded by changes in urbandevelopment plan.

OPGW

Optical Fibre Ground Wire (OPGW) is a revolutionary solution that enables synergies betweenefficient power distribution grids and high speed optical fibre-based networks, giving power utilitycompanies the unique capabilities of a telecom carrier or service provider.

OPGW replaces a conventional ground wire (or earth wire) to protect the transmission system fromlightning strikes and serves as a conductive medium for carrying fault currents to ground. It alsoacts as a medium for real-time monitoring and security of the transmission system over which it isinstalled doubling up for controls and networks.

The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part ofthe cable serves to bond adjacent towers to earth ground, and shields the high voltage conductorsfrom lightning strikes. The optical fibres within the cable can be used for high speed transmission ofdata, either for the electrical utility's own purposes of protection and control of the transmissionline, for the utility's own voice and data communication, or may be leased or sold to third parties toserve as a high-speed fibre interconnection between cities.

OPGW as a communication medium has unique advantages over buried optical fibre cable whereininstallation cost per kilometre is lower than a buried cable. Effectively, the optical circuits areprotected from accidental contact by the high voltage cables below (and by the elevation of theOPGW from ground).

A communications circuit carried by an overhead OPGW cable benefits from the lower likelihood ofaccidental damage due to excavation work, for example road expansion or by any kind of repairingwork of underground drainage system or water supply system.

Bare Overhead Conductors

Properties of Materials

Aluminium 1350

High purity electrical conductor (EC) grade aluminium (alloy 1350) has a conductivity of 61% IACS and UTS of160–185MPa.

Aluminium alloy 1120

Aluminium alloy 1120 has a conductivity of 59% IACS and UTS of 240–250MPa. This alloy can be considered a‘high tech’ version of EC grade aluminium and offers significant advantages over older type alloys, such asalloy 6201. Steel-reinforced aluminium alloy 1120 conductors have a high strength to weight ratio, resultingin small sags on long span lengths. Fittings for alloy 1120 conductors are similar to those used for EC gradealuminium conductors. Compared with alloy 1120, alloy 6201 conductors have poor electrical performance,are less resistant to corrosion, more susceptible to fatigue failure, more expensive and require the use ofspecial fittings.

Galvanised steel

Galvanised steel wire made from fully-killed steel with a carbon content of 0.6% has UTS of 1.31–1.39GPa. Itis galvanised by either a hot dip or electrolytic process to give a zinc coating mass of 200–260g/m2.

Aluminium-clad steel

Aluminium-clad steel has an aluminium cladding with a radial thickness not less than 5% of the overall wirediameter. It has a conductivity of 20.3% IACS and UTS of 1.27–1.34GPa. Conductors incorporating aluminium-clad steel for reinforcement have lower electrical resistance and provide better protection against corrosionthan those using galvanised steel.

Construction

The wires in all bare conductors are stranded concentrically with successive layers having an oppositedirection of lay, the outermost layer being right-handed. When required, a larger central wire (king-wire) isincluded in a conductor. The diameter of this wire is based on conductor design considerations and is usually5% greater than the surrounding wires. The incorporation of a king wire is often an advantage for ACSR typeconductors, as it ensures that the surrounding layer of wires fits firmly on the central wire. ACSR conductorsmay be subjected to corrosive conditions such as high pollution found in industrial areas or salt spray incoastal areas. The application of high melting point grease over the steel wires provides additional protectionagainst corrosion. Conductors incorporating aluminium-clad steel are more corrosion-resistant than thoseincorporating galvanised steel. Aluminium alloy 1120 conductors are becoming more popular asreplacements for steel-reinforced conductors in areas of high corrosion risk. The exposed surface ofaluminium wires can be specially treated to provide a dull finish when conductors are required to blend intothe environment. Aluminium alloy 1120 conductors may be identified by means of a blue threadincorporated within the conductor.

Low Voltage Aerial Bundled Cables

AS/NZS 3560 specifies the requirements of Aerial Bundled Cables with XLPE insulation for use up to 0.6/1kV.It is a result of considerable deliberation among supply authorities and manufacturers seeking to improve onthe overseas standard, and features unique tests to verify superior field service performance.

Conductor

All four conductors are manufactured from high conductivity high purity aluminium alloy 1350 and arestranded circular compacted. Based on extensive development testing and production research, the surfaceof the conductor is specially treated to improve adhesion of the insulation to the conductor. This isimportant because the installed cable tension is completely provided by this ‘adhesion’ or ‘friction’ betweenthe conductor and the insulation.

Insulation

The insulation consists of X-90UV, a cross-linked polyethylene with a minimum of 2% carbon black to provideadequate protection from ultra violet radiation. This material is far superior to PVC, in its ability to withstandhigher operating temperatures, is more robust during installation, and has much better (higher) insulationresistance values. For improved characteristics in fire or overload situations, X-FP-90 insulation is available.For this application, PGCNT uses a highly filled XLPE with greater levels of carbon black and other fillers. Bothinsulation types are tested at 80°C with a special adhesion test that simulates the conditions prevailing under

WWW.PGCABLES.NET.AU iv Ph: +61 2 4587 7172

tension at strain clamps to ensure no failure of insulation adhesion occurs in the field. X-FP-90 insulatedcables are additionally tested at the higher temperature of 120°C, and are also subjected to a heat radiationtest that simulates conditions prevalent in bush fires. The X-90UV material used by PGCNT passes the criteriatest at 105°C which provides our customer with a further safety margin over the Standard.

The cores

Each phase core is marked with numerals 1, 2 or 3 and with one rib, two ribs or three ribs to denote thethree phases. The neutral core carries equally spaced ribs right round the circumference. These ribs facilitateidentification of the phases and the neutral even when numerals cannot be properly seen due to bad light.To expedite ascertaining the approximate length of cable left on the drum, sequential six-digit numerals aremarked on one active core at one metre intervals. Drum lengths start at any number with the lowest numbernear the end at the drum barrel. The cores are laid up in a bundle with a left hand lay. Rating of LV-ABC isbased on a conductor operating temperature of 80°C.

High Voltage Aerial Bundled Cables

Two types of HV ABC are available:

Metallic Screened (MS HV ABC) and Non Metallic Screened (NMS HV ABC).

Metallic Screened High Voltage Aerial Bundled Cable conforming to AS/NZS 3599.1 incorporates a metallicscreen of copper wires and a galvanised steel messenger. Non-Metallic Screened High Voltage Aerial BundledCable conforming to AS/NZS 3599.2 is provided only with a semi-conductive screen and the fault currents arecarried by the high conductivity Aluminium Alloy (1120) catenary. NMS HV-ABC is smaller, lighter and lessexpensive than MS HV ABC.

Metallic Screened HV ABC

Conductors

Phase conductors are stranded circular compacted aluminium alloy 1350 to H68 condition. The standardcatenary is manufactured from galvanised stranded high tensile steel. For corrosive environments catenariesof aluminium clad steel are available.

Conductor Screen, Insulation and Insulation Screen

Semiconductive conductor screen, XLPE insulation and semiconductive insulation screen are triple extruded.The insulation screen is hand strippable without preheating and complies with strip ability and adhesiontests given in AS/NZS 3599.1. Figures and words “1 ONE,” “2 TWO” and “3 THREE” are printed on the insula-tion screen to identify the three phase cores. Alternative identification means are available on request. A wa-ter swellable textile tape is applied over the insulation screen to prevent longitudinal ingress of moisture inthe event of damage to the outer sheath.

Metallic Screen

The metallic screen comprises a layer of helically applied copper wires. For short circuit protection, two types

WWW.PGCABLES.NET.AU v Ph: +61 2 4587 7172

of screens, a light and a heavy duty, are available. A separator tape to prevent the penetration of sheathmaterial between the screen wires is applied over the metallic screen. On this design of cable it should benoted that the screens of individual cores are not in direct contact with each other and therefore the faultcurrent level is limited.

Sheath

High density polyethylene (HDPE) is used as the standard outer sheath of each phase core. In addition to theidentification on the cores, the sheaths of each phase cable are marked with phase numbers matching thoseof the cores. Furthermore, identification of the bundled cable comprises embossing of the words “PGCNT”the year of manufacture, and the voltage on the sheath or the use of printed tapes inserted throughout thelength under the sheath of a phase cable.
