1.1 ,This specification covers non-specular surface finishes on overhead aluminum electrical conductors. Overhead aluminum electrical conductors, when installed, typically have a shiny surface appearance. This “,reflective”, or “,specular”, surface can make a transmission line more noticeable in appearance against the background landscape. A factory treatment process of the outer surface of the aluminum wires can render the surface finish into a dull, non-reflective, matte grey finish. This non-reflective or “,de-glared”, surface finish allows the conductor to become less visible when observed from a distance and enables the transmission line to blend in with the skyline or landscape background.2
