Pressure Testing of Recyclable Transmission Lines (RTL's)

T4 cone

The T4 cone was the first cone to be laser scanned for its initial and deformed shapes.

Unfortunately, electronic pressure data was inadvertently not recorded during this test.

The following video shows how the cones are loaded into the pressure chamber. T4-Loading
(The bumping around that is heard is the sound of the scaffolding (not the cone!) hitting
the side of the pressure chamber.)

This video shows the laser scanner in operation--note that the camera had to be
set to infrared mode since the laser is otherwise invisible to the human eye. Laser scanner

The laser scanner was used to produce the plot below, that shows a bulge on
the left side of the figure.

                  Below is a picture of the laser scanner bearing assemby, followed by some pictures of
                    the T4 cone after the test.
