Aplicación
Líneas aéreas de transmisión y distribución primaria o secundaria.
Tiene menor peso y gran resistencia al esfuerzo mecánico lo cual permite grandes vanos en líneas de transmisión. Los conductores con lubricante son más resistentes a la corrosión, su uso es aconsejable en zonas con atmósferas salinas.
Normas de Fabricación
American Standard-ASTM B 399/B 399M
