Unjacketed

Unjacketed refers to something that lacks a jacket or protective covering. This term can be applied in various contexts, most commonly in relation to electrical cables and wires. An unjacketed cable is one where the individual insulated conductors are exposed, without an outer protective sheath or jacket. This lack of a jacket can make the cable more susceptible to physical damage, abrasion, and environmental factors such as moisture, chemicals, and extreme temperatures. Consequently, unjacketed cables are typically used in applications where such protections are not necessary or where flexibility is paramount, such as within conduit or in environments where they are not exposed to potential hazards.

The term can also be used more generally to describe any item that is not enclosed or protected by an outer layer. For example, an unjacketed book would be one without a dust jacket, or an unjacketed lens might refer to an optical component without a protective coating or housing. The absence of a jacket implies a reduced level of protection and potentially a lower cost, but also increased vulnerability. The suitability of using an unjacketed item depends entirely on the specific application and the conditions it will be subjected to.
