An electrical connector for connecting electrical power transmission lines where the electrical connector is capable of conducting 1×106 to 2.5×106 siemens per meter squared (S/m2), and includes a base metal having a surface layer doped with a conductive material dopant. The conductive dopant material improves the reliability and performance of the electrical connector. An electrical power transmission system includes electrical power transmission lines connected by the electrical connector, and a method of joining power transmission lines with the electrical connector.
