> Do you agree to currently tag this as tower:type=suspension and maybe later according to proposal as line_clamp=suspension? Is there an opposite of suspension in English?I only find "suspension" in IEC vocabulary
After perusing Electropedia (IEC), I noticed some of the clamp entries referred to 'posts', so I looked at power line equipment catalogs under insulators, and alongside Suspension Insulators, Spool Insulators, Pin Type Insulators, there is also a Post Insulators, and some engineering references. >From "The transmission and distribution of electrical energy <https://archive.org/details/in.ernet.dli.2015.65422>" 3rd ed. Cotton and Barber, page 165: There are three types used in connection with overhead lines, viz. : 1. Pin-type. 2. Suspension-type. 3. Strain-type.( includes 'Shackle'?) It seems the various 'clamps' are used in conjunction with the position / orientation dictated by the major type insulator ( top, middle, spool(with clevis)). Post Insulators seem to incorporate both support, stand-off, and insulating functions in all orientations ( pointing up, down or slantwise ). Probably the simplest antonym for 'suspension' conductor on bottom ) case is 'pin' ( conductor on top ), and if you want 'spool' for the minority conductor in the middle. Michael Patrick Data Ferret
