<p>A multi-shed suspension insulator comprises an insulator body 1, a metal cap 2 and a metal pin 4. The insulator body has at least two sheds 6,7, monolithic with the insulator body. To obtain the maximum withstand voltage with shortest insulator height, the ratio (L/P) of the surface leakage distance L (A to B) to the vertical shed pitch P is within the range of 5</=L/P</=9. In another embodiment (Fig. 2) the sheds 6,7 do not have skirts. In a further embodiment (Fig. 3) a small shed (8) is interposed between the others. Up to five sheds may be provided. <IMAGE></p> |
