Overhead line mast testing system
An overhead line mast testing system is a special system for testing the static strength of overhead line masts . An overhead line mast testing system consists of two steel frames and one or more foundations on which a sample of the overhead line mast to be tested can be built. The masts can be subjected to compressive and tensile forces and their behavior can be determined using suitable measuring methods using ropes mounted on the steel scaffolding and guided over the steel scaffolding to the masts to be tested.
Before setting up the adjacent BBC mast testing facility in Mannheim-Neckarau, the Deutsche Verbundgesellschaft (DVG), based in Heidelberg, carried out strength tests on high-voltage pylons on a test site near Mannheim-Rheinau in the 1950s , with the pylons being subjected to tension until they were buckled. The pictures show high-voltage pylons tested in this way in February 1958.
