TOP FITTING

RINGS

0 = Chain Eye 1 = IEC Ball 2 = Y-Clevis 3 = IEC Socket

Open Type 0 = No Ring Required A = 110/132kV, 250mm Line End Only

B = 220/230kV, 305mm Line End, 250mm Ground End C = 330/345kV, 300mm Line End, 300mm Ground End D = 400/500kV, 370mm Line End, 370mm Ground End

4 = IEC Straight Clevis 5 = Clevis (18mm only)

e) Top Fitting . Defines the top end fitting of your insulator. Fill in your selection in the box designated for “e.” For example, if you want a suspension insulator with an IEC Socket end fitting, you would place a “3” in the box designated for “e.”

Closed Type E = 110/132kV, 250mm Line End Only

g) Rings . Defines your need for a Corona Ring. Fill in your selection in the box designated for “g.” The example below shows a selection of a corona ring for 110/132kV, 250mm Line End Only. Thus, “A” was placed in the box designated for “g.” F = 220/230kV, 305mm Line End, 250mm Ground End G = 330/345kV, 300mm Line End, 300mm Ground End H = 400/500kV, 370mm Line End, 370mm Ground End
