- Abstract
ElectraNet SA (and predecessor organisations) has used the Stobie Pole as its standard overhead power line pole structure for more than 80 years. Up to the present, the tallest stobie poles used in transmission lines were 26m in height.
A feasibility study determined taller stobie poles up to 36m in height could provide a practical alternative structure type and be manufactured in a cost-effective manner. Positive benefits included greater likely acceptance for new lines traversing environmentally sensitive areas. This is because the stobie pole structure footprint is dramatically smaller than either lattice towers or other structures requiring guy supports.
In order to verify the structural performance and reliability of 36m stobie poles, ElectraNet SA implemented a full-scale load-testing program.
This paper outlines the key objectives of the load-testing program; describes the test arrangements implemented to achieve the objectives; and discusses conclusions drawn from the observed structural performance of the tall stobie poles.
The load test program included a total of six full-scale pole tests including three-off 36m pole tests. Proposed future studies include scale-model testing and development of a finite element model for use as a design tool.
