51317--9772-Coastal Environmental Field Trial of an Overhead Power Transmission Conductor

Picture for Coastal Environmental Field Trial of an Overhead Power Transmission Conductor
Available for download

Coastal Lima Peru is an aggressive atmosphere.  This reports a field trial of a high-temperature low-sag ACCR (aluminum conductor, composite reinforced) conductor. It contains aluminum and aluminum matrix composite constituents, and uses a greased configuration.

The coastal region of Lima Peru is an aggressive atmosphere classified by ISO 9223 as an S1P1 mixed atmosphere having high deposition rates of Cl- ions and SO2. Lima has little rain so the ions are not easily washed away but instead concentrate with daily fogs. Overhead power transmission conductors in this region are required to be both of all-aluminum constructions (no steel) and to have grease between layers in order to give longer environmental durability. This talk will report on an ongoing environmental field trial of a high-temperature low-sag ACCR conductor. The ACCR contains aluminum and aluminum matrix composite constituents and for the first time uses a greased configuration. Samples were periodically harvested from the field and characterized using microscopy and strength testing. A comparison in behavior is drawn between greased and ungreased conductors that shows the beneficial role of the grease between the layers for protecting the aluminum strands.

Key words: ACCR, conductor, corrosion, field trial, grease

Expansion has increased the risk of AC in pipelines. In this work, calculations of induced AC voltage and current are performed for scenarios involving: HVAC transmission powerline configuration, lateral distance to the transmission pipeline, and parallelism between the transmission lines, soil, and pipeline and coating properties.

Nuclear wastes are stored in large, underground carbon-steel storage tanks at the Hanford site. Carbon steels can become susceptible to localized corrosion. This paper presents the results of ongoing electrochemical investigations to understand the reasons behind the noble drift in the OCP of carbon steel in these waste simulants.

Calcium bromide is used in the coal fire power plant industry to help control mercury emissions. The objective of this study was to determine the effect of bromide additions in chloride-rich Wet Flue Gas Desulfurization slurries on the crevice corrosion resistance of commercially-available corrosion resistant alloys.
