Conductivity It’s true. Aluminum conductors carry twice the electrical current per pound as copper conductors. This is a signiﬁcant performance advantage that utilities depend on for the national power grid. In feeder cable applications, the same performance advantage of aluminum can be realized by using STABILOY aluminum alloy instead of copper. Insulation No question about it. STABILOY aluminum alloy conductors feature superior insulation. In fact, the cross-linked polyethylene (XLPE) insulation on STABILOY conductors performs better in cold impact, wet electrical and long-term aging tests. This makes it a better insulation for every application. Termination Why mix metals? STABILOY aluminum alloy conductors terminate safely with industry standard dual-rated aluminum lugs. The “similar metals” connection eliminates thermal expansion mismatch, which translates into a safe and reliable termination.
