RESEARCH ON THE THREADED CONNECTION SYSTEM FROM AlMgSi ALLOY FOR ELECTRICAL POWER CABLES UNDER VARIOUS CLAMPING LOADS.

This article presents strain gauge tests showing the force loads in the connection system of power cables, with AlMgSi sheer bolts. Among others, the analysis of the influence of the tightening torque of the clamping unit on the distribution of forces and the evaluation of the strain in the entire system was carried out. The knowledge of the force conditions and loads in the threaded connection system allowed to develop, with the use of Finite Element Method (FEM) modelling, the optimal geometry and material of elements for the power cable connection system.
