First, each wire is individually shielded with a polypropylene jacket. Second, an aluminum foil wraps around all of the pairs. Third, a metal braid shield is wrapped around the foil. Finally, a thick but flexible PVC jacket is wrapped around the metal braid.
The quality and strength of the shielding included with Predator Grizzly cables protect your data from RF noise and electrical interference. We highly recommend that you do not attempt to make your own Grizzly Cable.
