Results of investigations of the dielectric permittivity and dielectric loss tangent are presented for a wide frequency range. Physical and chemical properties of modified atactic polypropylene are investigated and experimental parameters of its adhesion to the steel and concrete surfaces are given. It is demonstrated that atactic polypropylene can be used as an electric insulator and water repellent to protect from corrosion metal structures and concrete products used in power engineering. Modification of atactic polypropylene increases the real component of the dielectric permittivity and decreases the dielectric loss tangent, thereby significantly decreasing its conductive properties. This can be used for electric insulation of energy-intensive units.
