Which German term means 'casting lead'?

The term that means 'casting lead' in German is "Massekabel." This term specifically refers to cables used in electrical systems that can involve the casting of lead for various applications, including in the manufacturing of electrical components. In contexts where lead is used in its molten form for casting, "Masse" may refer to the bulk material, while "Kabel" relates to the electrical aspect.

The other options do not align with the concept of casting lead. For instance, "Buchse" means 'socket' or 'bushing,' which pertains to a component that holds another part or provides a passage for wiring. "Grat" refers to 'burr,' often material that has been left over from cutting or machining, which would not involve the concept of casting. Finally, "Kronenmutter" means 'crown nut,' a type of fastener used to secure other components together, which is also unrelated to the process of casting lead.
