Pole testing in China for transmission works at Dugald River
Zinfra’s National Business Development Manager and transmission line expert, Barney Manga, travelled to Nanjing and Beijing in China recently to inspect the quality of the factory and materials used to manufacture steel 220kV transmission poles and observe load testing of the poles.

Approximately 202 transmission poles are required for the Dugald River Mine project for client MMG in Cloncurry, Queensland, where Zinfra is delivering the design and construction of approximately 70 kilometres of 220kV overhead transmission lines using helicopter stringing methods.

Mr Manga witnessed the massive poles being subjected to various weight loadings to eight different parts of the pole (pictured). The weight load testing ensures the poles can withstand load, and also tests their integrity in wind, in this case up to 180 kilometres an hour.
