Axial impact test

The objective of the test is to investigate if the cable, such as a conductor or catenary wire, could sustain a high dynamic impact load. Such an impact can potentially be generated by accidents during operation of the conductor/wire e.g. tree damage.

The axial impact test can be carried out on stranded conductor, catenary wires or individual wires, according to customer specifications.

Our strengths
Description

Our lab, one of the few to perform this type of tests, has developed a unique expertise in impact testing.
Lamifil’s test environment features high speed monitoring.
Impact resulting from up to 4m drop height can be simulated.

A sample with mounted compression clamps is prepared, the free length between the compression clamps is approximately 3m;
The conductor is suspended vertically with a pretension of 200 kg to straighten the conductor;
A dynamic load is applied by dropping 666 kg weight from an elevation of 4m;
The measurement sample frequency of the load cell is 2500 measurements/s;
A full report is prepared including test object data, test description, set-up, procedure, load vs. time curve and conclusions.
