What are the two types of cable jacket types?

The correct answer identifies the two primary categories of cable jacket materials based on their thermal properties and structure. Elastomer and thermoplastic represent these classifications well.

Elastomers are materials that exhibit elastic properties, making them flexible and capable of returning to their original shape after deformation. This characteristic is essential for cables that need to withstand bending and twisting during installation and use, providing durability and resistance to environmental stressors.

Thermoplastics, on the other hand, are materials that can be reshaped upon heating and solidify upon cooling. This attribute allows for ease of manufacturing and enables the production of cables with various shapes and sizes. Thermoplastics are often used for insulation and protective jackets because they provide good mechanical strength, chemical resistance, and waterproofing properties.

Together, these two categories encompass the majority of cable jacket materials, offering a range of performance characteristics that cater to different applications in electrical systems.

The other options listed refer to specific materials or metal types that do not accurately align with the general classifications of cable jackets.
