Calculation of conductor tensions of a tension angle support taking into acount shifting of the pole body

The problem considered here was treated in Ref. [1] for particular case of tension-line support. This paper deals with the influence of shifting (declination) of a tension-angle support on conductor tensions and sags in neighbouring sections of an overhead distribution line. The overhead line designed with reinforced concrete pole and steel reinforced aluminium conductors is analysed. Shifting of tension-angle support is caused either by changing of conductor temperatures and/or different maximum working conductor tensions in two neighbouring sections (spans) defined by designer of overhead line. Shifting of the support caused only by different conductor tensions at critical temperature is treated here. Influence of temperature on conductor tensions and sags will be the subject of some other paper. It is pointed out that problem which apears in Ref. [1], can be treated as a special case of approachment exposed (explained) here. We hope that the matter is comprehensively treated.
