With there being so many different types of wire out there you will find that the StripMeister E1000 can strip a large majority of wire. We have tested Southwire cloth coated cable that is 750KCMIL with an OD of ~1.3' and the thickness of the insulation jacket was ~0.2" . The StripMeister E1000 stripped this wire with no problems.
If you have a specific wire you would like StripMeister to test for you please call us at 1-800-681-8494 and we can assist you with testing your wire on our machines.
