Description
図3(B)は、例えば特許文献1の図1に示されるような直流同軸ケーブル16を使用し、その直流同軸ケーブル16の主導体17を正極性の直流送電用に使用し、主導体17の外周に絶縁層を介して設けた中性線導体18を中性線として使用し、負極性の直流送電用に別の直流ケーブル19(直流同軸ケーブルでもよい)を使用する方式である。
図3(C)は、双極送電用の直流同軸ケーブル(特許文献2参照)を用いた方式であり、双極送電用直流同軸ケーブル20の中心導体21に正極性の直流を接続し、第2の導体22に負極性の直流を接続し、鉛被23をアースに接続して、双極送電し、中性線回路は別の中性線ケーブル24を使用するものである。
