NaKorid GmbH

NaKorid Isorail is the reliable and EBA-approved repair method for insulated joints with DB Netz approval since 2020. The new repair method with NaKorid Isorail is cheap, quick and saves you time-consuming work, such as thermite welding of the insulated joint on the route.

Until now, the insulated joint was changed when the susceptibility to faults due to over-rolling had reached a critical level (red illumination). NaKorid Isorail now enables the timely installation of a repair insert during maintenance to create an electrically insulating layer that prevents rolling over.

The NaKorid Isorail insert replaces old insulated joints and makes thermite welding superfluous.
