Insulators hold, insulate, and terminate cables. Again, the rule for annotations is to place the marker at the bolt on the pole. Click at the insulator height and search "insulator" in the dropdown. Like the arm, you will want to add the insulator spec attribute if doing PLA.
If the insulator is attached to an arm, simply place the insulator marker in the photo (slightly below the arm marker is a good place to start). We will move it to the arm in a later step.
If performing PLA, all power cables will need to have insulators called out with specs. For most pole loading engines, it is not required to have comms attachments labeled on 3-bolt insulators.
*If exporting to OCALC, you will need insulators with the three-bolt insulator spec annotated.
Pins are used for primaries and can be on poles or on arms and look bell-shaped. Be on the lookout for double pins.
Suspensions will be framed vertically on the pole and bisect the aerial cables. These are used for primaries.
Deadends terminate cables at the pole. Look for deadends where cables are detached going in opposite directions or at the end of routes. These could be on arms or attached directly to the pole and used for any cable type.
Tangents will be used with neutrals and secondaries and clamp down on the cable.
