Insulator with increased insulation capability

摘要

An insulator has a partially hydrophobic surface (6) and a core made from an insulating material with a hydrophobic surface coating (8). The surface coating contains polytetrafluoroethylene and hydrophobic material that is dissolvable in solvent. The hydrophobic material is completely or partial made from amorphous fluoropolymer, which is an amorphous modification of Teflon(RTM). The hydrophobic material is completely or partly made from polysiloxane connection or alkylsilane. The hydrophobic surface coating has a thickness in the range of nanometers to micrometers. An independent claim is also included for an electrical device including an insulator for fastening an electrical component in a housing.
