POWER CABLE Russian patent published in 2010 - IPC H01B3/22 H01B3/44 

FIELD: power engineering.

SUBSTANCE: power cable comprising at least one electric conductor and at least one extruded coating layer, including thermoplastic polymer material with addition of liquid dielectric, in which specified liquid dielectric contains compound of formula (I) X-A-X'; where A represents monocyclic aromatic fragment or at least partially aromatic condensed polycyclic fragment; and also at least one fragment from X and X', which is metal or aliphatic fragment; in both cases this fragment may be substituted and/or interrupted with one or more groups selected from ketogroup, alkoxy group, alkyl thio group, mercapto group, hydroxy alkyl, hydroxyl, where the other is hydrogen. Proposed compound has ratio of carbon atoms number in aromatic fragment to overall number of carbon atoms as equal to 0.6 or more.

EFFECT: improved operational parametres of cable with proposed extruded coating layer.
