Sheathed pur jacket cables and unsheathed pur jacket cables differ in external protection, physical durability, environmental adaptability, installation flexibility, and cost. Sheathed cables have an additional outer layer made of plastic, rubber, or other materials, providing protection against physical damage, chemical corrosion, and environmental factors. This makes them suitable for harsh environments.
Unsheathed pur jacketed cables lack this outer protective layer, only having internal insulation around the conductors. They are lighter and more flexible but offer less protection, making them suitable for less demanding environments.
The main difference is the presence of an external protective layer.
