Kalestead offers an extensive range of thermoplastic materials for electrical insulation. These materials may be used over the conductors (to make cores) and over the whole cable (to make a protective jacket, or sheath).
Some of the cables we make have more than one sheath. This is common in submersible cables or where extra protection/insulation is required within the cable.
Our thermoplastic compounds cover a huge range of physical and thermal properties.
