Corrosion Performence of AAAC and ACSR

05/16/2012 11:30 PM

we found that ACSR conductor is more corrosion (galvanic) prone than AAAC. But in CBIP lab test suggest that AAAC is more prone to pitting corrosion than ACSR conductor. Therefore for selection of power transmission line conductor in coastal and industrial area which type of conductor is preferrable and why?

Follow the prevailing local standards applicable to the country and region of installation.

ACSR has a poorer resistance to (galvanic) corrosion,as it contains steel,which is prone to rust. AAAC has a better corrosion resistance, as they are largely or completely aluminium. Pitting is localized galvanic corrosion.

When routing transmission line,both the aspects of galvanic and pitting corrosion are to be considered locationwise. Conducter with lesser total (galvanic and pitting) corrosion is to be selected.

My requirement is that the rate of corrosion for ACSR and AAAC for

1.galvanic and

2.ptiiting corrosion

with some graphical representation.
