  1. Hot – Pluggable AMS Connectors • Specificservicerequirements • Design Concept • Development steps

  2. AMS • The ideaistoavoiddisconnectorsbydisconnectingstandardconnectors. • Someofthe AMS connectorsshallbeoperatedunder Hot lineworkingconditions (145kV) = „Hot pluggable“ • Other connectorstobeoperatedwithoutvoltage(275-400kV), (SubCondeveloped a widerangeoftheseconnectortypes but theyare not infocusoftodayspresentation
