OLIS provides retrofit insulation for overhead conductors to help prevent electrical outages caused by trees or wildlife coming into the contact with distribution lines. It is manufactured from high quality Non Tracking Cross linked Polyolefin material. Easy & quick installation widely used in the electrification railway and naked –wire in substation for insulating protection. These cover are designed to insulate existing bare lines without costly conductor replacement expenditure or additional line hardware.
