Description
Summary:For pt.I see ibid., vol.7, no.2, p. 581-7 (1992). An analysis is presented of the test results relative to estimated end-of-life values. The remaining useful life of conductors can be estimated from the curves of progressive degradation. Air pollution studies have led to an environmental corrosion index, which has been correlated with remaining life based on the torsional ductility of steel core wires. This has been used to map expected conductor life across the province. The average service life is found to vary between about 67 and 77 years, depending on the local contamination level.< >
