In high voltage lines the coupling between the tension string and the conductor is made by dead end clamps. The most used dead clamp is the compressed type. It is composed by a steel internal body and an aluminium alloy sleeve compressed on the conductor and on the internal body. In case of ACSR conductors, the terminal part of the internal body is compressed on the steel core of the conductor. After compression the aluminium sleeve shall become an integral part of the conductor. Therefore, the quality of this fitting is essential. The aluminium alloy used is chosen with low content of copper to avoid corrosion due to electrolytic couple and it is thermally treated to give it the necessary plasticity for a good and homogeneous compression.
