Heliformed ® Line Fittings Armour Rods Type AAR - Aluminium Alloy for AAC, AAAC and ACSR Type CAR - Copper Alloy for Copper Conductors Type SAR - Galvanised Steel for SC/GZ Conductors Type LAR - Aluminium Clad Steel for SC/AC Conductors Identification Tag Colour Code & Centre Mark Application Protection of conductors against bending & compressive stresses. Protection against abrasion & arcing damage. Repair of conductors having no more than 20% of outer strands damaged or broken. Guide to Usage As the degree of protection in specific situations is affected by such factors as line design, temperature, tension, exposure to wind flow, vibration history, etc., the following recommendations are made: (i) Armour Rods should be regarded as minimum protection for clamp style supports or suspension arrangements. Heliformed ® Line Fittings (ii) (iii) 7-16 They should be considered as mimimum protection on hand tied, pin type construction of span lengths greater than 90M in urban areas, having no history of vibration. Armour Rods are not designed to act as vibration dampers. Their role is to provide conductors with an extra degree of protection at support points. In areas where a history of vibration is known, or where vibration is suspected, the supplementary use of Type SVD Heliformed ® Spiral Vibration or Dogbone ® Dampers should be considered. (iv) On pin type construction, the use of Helities ® are recommended as being superior to usual armour-clamp arrangements. (v) At suspension points Heliformed ® type HSU Suspension Units are recommended as superior to usual armour-clamp arrangements. Restorative Repair Armour Rods may be used to restore full conductivity and strength to aluminium, ACSR and copper conductors, where damage is outside of the support area and does not exceed 20% of the outer strand layer. Dulmison should be consulted when damage is located at the point of support. The conductor should be scratch brushed and greased prior to the application of Armour Rods used for repair. Tapping Heliformed ® Armour Rods may be used as tap armour to protect conductors from wear and flashover damage under hot line taps. Where tapping clamps are to be installed over the Armour Rods a moisture inhibitor, e.g. Alminox, should be applied. The conductor should be scratch brushed and greased prior to the application of Armour Rods used for tapping. www.dulmison.com.au
