Dissertation of Materials Engineering at the Technological University, Prof.Dr.Akram Rahim Gabr,prof.Dr. Fadel Geyad Attia and Eng. Hussain Ali Alwan, published a joint scientific paper entitled Effect of Caravine Addition on Electrical Transmission Relays on Electrical Conductivity and Durability Properties in the Journal of the Elsevier Publishing House, No. 119 of 2017.
 The study discussed the importance of recycle used and damaged waste from the aluminum wires which are used in the lines of transmission of electric power (high pressure lines), which are hundreds of tons in the warehouses of the Ministry of Electricity and re-operation of these wires by adding the caravans and improve their specifications in terms of electrical conductivity and mechanical pull durability to obtain higher specifications Of the standard specifications.
