Neutral conductor grounding system |
摘要 |
System neutral to earth grounding, over the entire length of an electrical cable is achieved by adding one or more strips of semi-conductive material over the helically or otherwise wound concentric neutral conductors and completing the cable jacket with insulating material. The strip engages the soil when buried to provide a continuous ground path for the neutral conductors. In a second form protrusions of semi-conductive material project from a semi-conductive layer and encircle certain ports of the neutral conductors while the remainder are partially surrounded by the semi-conductive layer. Insulating material segments complete the cable jacket. The free ends of the protrusions engage the soil about the cable to provide a continuous ground for the neutral conductors helically wound or extending in parallel with the cable longitudinal axis.
