Material Properties / Testing

All of Pole Life Systems' products have been thoroughly tested according to ANSI standards.

 

A special Thank You to our partners at The University of Alabama at Birmingham Material Science & Engineering Department for the following video. This video will show Pole Life Systems’ products put to a physical assembly compression test to 2500 lbs.  This represents a loading of 5:1 – five times the normal loading we would expect for 795 feeder wire.  The 5/8” insulator bolt and PLS products where moved above the pole to prevent any wood pole support for this test.  As you will see in this short video, that we broke or bent several standard utility parts without any damage to our products.
