Typical Properties of "Kraft Insulation"

Kraft Insulation is produced in multi-layer form on a modified wet machine from an electrical grade, unbleached Kraft wood pulp. The dry finished sheets contain no sizing, coloring or other materials, which would contaminate natural or synthetic impregnating oils.

Kraft Insulation is used for transformer layer insulation, capacitor can liner and in many other applications where the ultimate in electrical and physical strengths are required.
