A polymer composition has at least one thermoplastic polymer material and a dielectric liquid of improved polarity, to a process for preparing said polymer composition, to a cable comprising at least one electrically insulating layer obtained from the polymer composition, and to a process for preparing the cable.

Polymer composition comprising a dielectric liquid of improved polarity

A polymer mixture is provided suitable for use in a cable as a sensor polymer mixture for determining the mechanical and/or electrical stability or aging of a cable. The method may use the determination of changes in the polymer mixture, especially for determination of the aging and/or stability, for example as a measure for estimation of the wear or the remaining service life of a cable having the polymer mixture.

Use of a polymer mixture as a sensor mixture

A heat-shrinkable protective element having at least one protective layer is obtained from a polymeric composition having a polymer material, where the polymeric composition additionally has an electrically conducting filler having a BET specific surface of at least 100 m/g according to Standard ASTM D 6556.

Heat-shrinkable protective element
