Electrical Grade Aluminum

[neduet]

What is Electrical Grade Aluminum for Tubular BusBars. i am confused between 6063 and T6 or T5 and what is BS 2898 and BS 159?

[Cake of Doom]

BS 2898:1970 Specification for wrought aluminium and aluminium alloys for electrical purposes.

BS 159:1992 Specification for high-voltage busbars and busbar connections

You'll have to double check and make sure the specs in these standards haven't been superseded by the current BS EN standards.
