Zusammenfassung:	The frequency dependences of electrical conductivity with both real and imaginary components of a dielectric permittivity of polydimethylsiloxane oil suspensions filled by halloysite nanotubes having different amount of water are studied by dielectric spectroscopy. An analysis of frequency dependences of dielectric loss on temperature made it possible to assess the energy of activation of relaxation processes proceeded in suspensions. An effect of a low amount of water on the relaxation processes is considered.
