There are several types of insulators you can add to an assembly like pin, post, spool, or suspension. Follow these steps to add insulators to an assembly:

Because Assembly Creator does not model the exact physical specifications for the insulators, the Overhead Design Analysis (OHDA) tool will not calculate transverse wind loads on the equipment. |
OHDA Assembly Creator does not allow users to place insulators on the middle cross arm of a triple cross arm assembly (the inner board). You might be inclined to add insulators to the first cross arm on the assembly, then continue to add cross arms until you have added all three, but we recommend adding all the cross arms first, then placing insulators on the outer cross arms. This will help you build assemblies more efficiently. Here are the recommendations when adding insulators to cross arms:
Add insulators to that cross arm.
Add insulators to either cross arm.
Add insulators to either the first or third cross arm (the two outer cross arms). Add all cross arms first, then add insulators to the appropriate cross arms.
