| Abstract | ||
| The overhead wire systems for transmission of electrical power with high voltage of 132 up to 400kV use straight and parallel groove connectors to join aluminum and copper wires in a transmission network. In this work, straight and parallel grooves connectors of aluminum and copper cables have been manufactured to transmit high tension power of 132KV. A joint compound material has been painted at the interface between Al and Cu metals within the connectors. The joint compound is prepared in a laboratory with high resistance of corrosion. The manufacturing connectors are tested to study their mechanical and electrical properties. The results shown that the resistance between the terminals of Al and Cu with the anticorrosion material between them is 0.1Ω. While the Tensile Test Report for the specimen of straight connectors confirmes the value of maximum tensile force of 5.75 tone. The failure section occurred at 2cm inside the Cu cable and not inside the manufacturing straight connectors.These manufacturing connectors are examined successfully for 6 months within the transmission network under the authority of the General Company for Generation and Transportation of Electrical Power in Basra. A certificate has been issued by this company confirming the good quality for the application of these connectors. | ||
