CONNECTINGWITH COPPERIS CONNECTING WITHTRUSTThere has never been a question of reliability when itcomes to copper-to-copper connectors in electricalapplications. The real question is how reliable are othercombinations of electrical connectors compared to allcopper connectors.Powertech Labs were commissioned to perform an in-depthstudy on aluminum-to-aluminum, aluminum-to-copper, andcopper-to-copper connectors. The photos shown here aredocumented comparisons of these three combinationsbefore and after 2000 hours of intensive testing, whichincluded current burst testing. The copper-to-copperconnectors had the least corrosive build-up andretained the highest electrical conductivity.The study and its results are outlined inour publication “Connecting with Copperis Connecting with Trust”.
