Abstract
This paper presents a method of testing some connection elements used in the construction of OHL – overhead power lines. The testing of the clamps during thermal cycles was carried out in accordance with the provisions of the SR EN 61284:2000 standard, corresponding to IEC 61284:1997, and the results obtained after the testing are presented. It can be seen that this type of test provides the beneficiaries with essential information regarding the state of the equipment, and allows the estimation of an optimal duration of the equipment’s operation.
