Conductor type – AACAAC Full Tension Midspan Joints, are manufactured from an Aluminium extrusion, equivalent instrength to the conductor onto which the fitting is applied.

Each fitting is manufactured with internal and external tapers, to eliminate stresses associatedwith compression, and reduce corona discharge.

Each fitting is clearly marked with the compression length, the applicable conductor stranding,and the appropriate compression die size. All design parameters for the items in this section arein accordance with AS1154.

General Recommendations:Dogbone Dampers are designed to eliminate conductorfatigue damage and line maintenance costs by effectivelydiminishing aeolian vibration, thereby allowing increasedline tensions. The messenger cable and unique dogboneshape of the masses are designed to achieve optimalenergy dissipation for minimal clamp movement. Themessenger cable and dogbone weights are matched to give additional resonant modes and widereffective frequency response. The mechanical impedance of the damper is matched to theconductor to optimise performance. The offset dogbone shaped masses introduces a torsionalmode of vibration damping not present in conventional Stockbridge type dampers.

The range of Dogbone Vibration Dampers is a development resulting from our extensiveexperience and research in the field of conductor vibration control. The Dogbone concept is basedon the known and proven principles of the Stockbridge Damper but embodies improvementswhich increase both power dissipation and range of frequency response beyond those of aStockbridge Damper. The performance of the Dogbone Damper has been further improved usingthe latest CIGRE and IEEE recommended methods including I.S.W.R. Power Dissipation andMechanical Impedance Testing.

Radio Interference Voltage (RIV):Dogbone Dampers are designed to be corona free at all operating voltages.

Placement:Due to the many parameters involved and the exhaustive tests conducted by Dulmison foroptimum damper placement and performance, it is recommended that Dulmison be consulted forexact damper requirements.

Option:Armour Rods can be supplied for added protection to OPGW Cable. See page 7-16 for details.

Dulmison Spiral Vibration Dampers are designed for use on conductors and guy wires rangingfrom 4.42mm to 19.30mm.They are designed to reduce aeolian vibration by acting as aninterference device for the aeolian vibration pattern, and are generally the most effective devicesfor use on small diameter conductors and earthwires. Dulmison Spiral Vibration Dampers aremanufactured from UV stable, high impact PVC and are suitable for use in ambient temperaturesranging from -40oC to 70oC. Further information is shown on page 7-30 of this catalogue.

Materials:Spacer, body, keeper, and Posilok clamp fastener - high strength aluminiumalloy.Clamp liner - an elastomer compound specially formulated for resistance toozone, ultraviolet, weathering, high and low temperature variations andcompression set. The conductor range and part number is moulded into theinside of each liner.

Posilok Twin Spacer Dampers are available for conductor sizes ranging from18mm to 35mm and for spacing ranging from 200mm to 520mm. DulmisonPosilok Twin Spacers have been successfully used for over 25 years inAustralia, USA, UK and many other countries. Posilok Twin Spacers featurean elastomer lined clamp that minimises damaging static compressivestresses on the conductor while providing high slip strength. The clamp actionof the Posilok makes this spacer easy to use with the clamp being fastenedby the action of the locking pin. This method of clamping ensures that theclamp is always properly fastened, with a controlled amount of force exertedthrough the rubber onto the conductor.

General Recommendations:Posilok Spacers are designed to maintain specified subconductor spacing. Furthermore they aredesigned to withstand the forces and movements caused by transient conditions such as shortcircuit differential icing and wind loading, without either causing damage to the subconductors orsustaining damage themselves. Dulmison’s exclusive Posilok fastener maintains a clamping force,independent of the installing lineman. The Posilok clamp design was developed specifically toeliminate the variables involved with other types of fasteners. When properly installed it exerts apositive vibration proof grip on the conductor. Correct installation is easily verified from the ground.

The Posilok spacer is flexible enough to allow some longitudinal movement between sub-conductors, and yet rigid enough to restrain the subconductors under adverse conditions. Theyprovide a smooth, unitised construction which minimises corona and presents a low level of RIV.The range of Posilok spacers are designed to accommodate all conductor sizes, all EHV voltages,and all bundle configurations.

Radio Interference Voltage (RIV) and Corona:Posilok spacers are designed to have satisfactory performance commensurate with the operatingvoltage of the transmission line.

Vibration:Although the elastomer cushioned housing is designed to minimise conductor damage, vibrationdampers must be used on lines subjected to aeolian vibration.

Bolted Option (Cast Bar Spacer):Cast bar spacers are available to suit most Australian standardconductors in twin, triple and four conductor configurations withspacings from 70mm to 520mm. Cast bar spacers are used invarying applications in substations such as overhead strung busbars and down droppers. They can also be used in transmissionline applications for jumper (pilot) strings.

especially compounded for resistance to ozone, weathering,extreme high and low temperatures and compression set. Theconductor range is moulded into the inside of each insert.

General Recommendations:Spacer Dampers are recommended for multi-conductorbundles with industry standard spacing. The Spacer Damperis designed to withstand the forces and movements caused bytransient conditions such as short circuit, differential icing andwind loading, without either causing damage to thesubconductors or sustaining damage themselves. The designaccommodates both longitudinal movement of thesubconductors, vertical sag differences, as well ascompressive and tensil forces. When the Spacer Damperis installed in accordance with Dulmison’s recommendationsfor subspan lengths, it constitutes a system which replacesconventional spacers and vibration dampers. SpacerDampers will control both aeolian vibration andsubconductor oscillation to levels recognised as acceptablewithin the industry and to the customers expressed needs.Dulmison will tailor the recommendations to terrain anddesign parameters.

Corona and RIV:Spacer Dampers are designed to have a satisfactoryperformance commensurate with the operating voltage ofthe transmission line.

Fault Currents:All of Dulmison’s Spacer Dampers are designed for a minimum compressive withstand loadbetween clamps of 1130kg and a minimum tensile to withstand load of 560kg.

Placement:Due to the many factors involved in designing an effective spacer damper system, it isrecommended that Dulmison be consulted for specific recommendations on both the choice ofSpacer Dampers and placement.

Damping:Spacer Dampers can accommodate torsional clamp arm movement of plus or minus 13 degrees,conical clamp arm movement of plus or minus 8 degrees, and longitudinal movement of plus orminus 38mm. These are possible because of the properties of our elastomeric damping elements.There are two per arm, one on each side. They are especially compounded to give long life underconditions of ozone, ultra violet light, anticipated temperature extremes, and continual conductormotion. Their ability to dampen over many years has been well established throughout the worldin all types of climates.
