Abstract :
WHAT happened to a Hochstadter compression-type cable in London, England, when an aerial bomb struck nearby may be seen from the accompanying illustration. Other than being forced slightly out of its original position and the enclosing pipe being dented in one place, the cable was not damaged and continued in service without interruption. The inset shows a closeup at the point where the cable enclosure was dented, the corrosion-protective covering having been removed over a short length. Adjacent cables were put out of commission, leaving the compression cable to carry the entire load for the areas it serves, and other underground structures were badly damaged. The bombing occurred near the point where the cable enters the substation
