TracFeed® STR section insulator

Section insulator

TracFeed® STR

Easy-to-install security

TracFeed® STR has proven itself over decades for subdividing contact lines into feeder sections at railway stations, turnouts and during structural alteration work. TracFeed® STR section insulators can be installed directly in the contact line in a short period of time. The suspension makes it easy to regulate the installation position. Not least because of the solid construction method and the materials used, TracFeed® STR section insulators from Rail Power Systems have a very long life expectancy with low maintenance requirements.
