Regards a support where continuous underside line is hold by vertical suspension sets.
A Suspension set (466-12-03) is an assembly of strain link and a clamp to support a line/cable at the assembly lower end. Suspension supports aren't designed to preserve the line tension but the line isn't expected to move due to clamps. Insulators are used as link in case of bare power conductors.
A suspension has no moving part and usually prevent line to move longitudinally although this is not mandatory. This is the default type and doesn't need to be tagged. However it may be useful to tag a suspension support if it is used as an angle tower (an anchor tower would normally be expected here).
|A pole can host several different configuration like this one. Suffixes help to give all details about line supported by the pole.
|Wood post insulators supports live wires of electric fences. Despite the cable can move through the insulator, this is not a pulley but a suspension since there is no moving part in the support and it is not designed to follow line movement like an actual pulley does.
