The axial impact test is performed to measure the mechanical performance of a conductor when subjected to high dynamic impact load.
The TTDTTC instrumented striker system far exceeds the specification with 1,000,000 points per test over any desired time interval. Further, our design not allows automated control of the traveler drop height setting, but it will be possible to load and pretension the cable from the ground. We did include the requested ladder, but it will not be needed for routine testing.
The impact velocity of 8 m/sec can be achieved in about 3.4 m of free fall. Therefore, the free fall height need only be 4 m. Also, there is no need for an anti-rebound device if the cable is not tested a second time.
