Default Re: Dynamic vs Static Cable Stytems, in the upper canopy

Funny that, I asked here and we have some responses.

Rigguy Wirestop fasteners for cable

Critters are chewing through dynamic systems.

Jim, what is the stretch factor of dynamic systems? In other words lets say the system (dynamic cord) can take 10tonne, how much will it stretch before it breaks. Now in the rock climbing rope world for instance figures of 50% crop up, with say static rigging lines like we use it's only about 10% (to breakage that is) and under normal use only around 3%

So what I'm trying to figure out is you have a dynamic system installed across a span of say 10m and it will stretch how much before it breaks? Maybe 5m which means the leader would have broken, please, save me Googling and researching I'm sure the manf of dynamic systems have to provide this data.
