Abstract

La présente invention concerne un multipode (1, 3) pour la production d’aluminium par électrolyse ayant un axe longitudinal (AL), un axe transversal (AT) et une axe vertical (AV), ledit multipode (1, 3) pouvant être mécaniquement et électriquement lié à deux anodes (22, 42)et un support anodique (21, 41), ledit multipode (1, 3) comprenant : deux rangées (I, II) parallèles comprenant chacune une pluralité de rondins (13,33) configurées pour être connectées auxdites anodes (22, 42),au moins une barre (14, 34) coopérant avec chaque une desdites deux rangées (I, II) mécaniquement et électriquement etun corps (11, 31) reliant les deux rangées (I,II) et étant configuré pour être connecté au support anodique (21, 41).
