  SIS100 will be op­er­at­ed with high in­ten­si­ty heavy-ion and pro­ton beams. The re­duc­tion of ring impedances is there­fore of great im­por­tance in order to avoid co­her­ent beam in­sta­bil­i­ties. The kick­er sys­tem is one of the main con­trib­u­tors to the over­all ring impedance in SIS100. This paper will focus on the con­tri­bu­tion of the ex­ter­nal net­work to the kick­er impedance. Cal­cu­la­tions as well as ex­per­i­men­tal impedance mea­sure­ments of the net­work con­tri­bu­tion have al­ready been car­ried out for the SIS18 and ESR kick­ers. The SIS100 will be equipped with a bipo­lar kick­er sys­tem, which uses a Pulse Form­ing Net­work (PFN) as en­er­gy stor­age. For po­ten­tial de­tach­ment pur­pos­es an in­su­la­tion trans­former will be in­stalled. Since this setup is new in sev­er­al ways it is im­por­tant to know its con­tri­bu­tion to the cou­pling impedance of the kick­er sys­tem. In this con­tri­bu­tion the cor­re­spond­ing nu­mer­i­cal cal­cu­la­tion is pre­sent­ed.
