PETH sheath is described as which level of strength?

Jacket strength classifications describe how much pulling and external stress a cable’s outer sheath can withstand. A PETH sheath is an unreinforced polymer jacket, which offers less resistance to tension, abrasion, and environmental damage than reinforced or armored jackets. Because of that lower resistance, its strength level is described as weak. In practice, this means tighter limits on installation tension and more careful handling, and it signals that you’d choose stronger shielding or add strength members if you need greater ruggedness. Descriptors like moderate, strong, or very strong would imply tougher, reinforced materials, which doesn’t apply to a PETH sheath.
