AI Technical Summary
【0039】 本発明の利点は、本明細書の他の箇所においても記載されており、当該利点には、ケーブルの長さ/距離にわたる電力損失および電圧低下の低減が含まれる。適切には、容量性ケーブルは、これらの利点を実現し、かつ電力システム設計に適したものとするに足る有意な長さを有する。本発明の利点は、交流の周波数が高いほど、より短いケーブル長で実現される。例えば、容量性ケーブルの長さは、概して1m以上もしくは5m以上、概して25m以上、100m以上、特に、200m以上および500m以上である。本発明の用途としては、例えば、10kHz以上の非常に高い周波数の電力の伝導が含まれるが、その場合、1m以上や5m以上といった非常に短いケーブル長でも利点がある。本発明の用途は、事実上、容量性ケーブルである送電線であるケーブルを含む実施形態にまで及び、これらの長さは、1km以上、好ましくは5km以上、さらには10km以上である。電力グリッドにおける使用では、ケーブルは、100km以上、あるいはそれよりもさらに長くてもよく、例えば、数百キロメートルの長さであってもよい。
