Insulated rail joint R-65 — a set of components designed to create insulated joints for R-65 rails in railway automatic block, interlocking, and signaling systems. It provides a strong mechanical connection of rails and reliable electrical insulation between them under all operating conditions.

Description and design

The R-65 insulated rail joint is manufactured in accordance with DSTU 4344:2004 and consists of two steel fishplates, insulating pads, bushings, and fastening elements. The fishplates are made of high-strength structural steel 09G2S, with a profile fully matching the geometry of the R-65 rail. Dielectric pads and bushings installed between the elements prevent electrical current flow between rails and bolts. The design maintains its insulating properties under temperature fluctuations, vibrations, and high humidity.

Insulating pads made of fiberglass laminate, PTFE (fluoroplastic), or polyamide;
Bushings ensure complete electrical separation of bolts and fishplates;
Fishplate surfaces are protected with anti-corrosion and electrical insulating coating;
Precise geometry ensures reliable fixation of rails in the joint;
Insulation resistance maintained at not less than 10 MΩ at humidity up to 98%.

Application

The R-65 insulated rail joint is used on mainline, station, and turnout sections of railway tracks equipped with automatic block, interlocking, and signaling systems. It is applied to separate electrical track sections and isolate adjacent rails while preserving the mechanical strength of the joint.

Advantages of R-65 insulated rail joints:

High mechanical strength under dynamic and thermal loads;
Complete electrical insulation even in high-humidity conditions;
Long service life and resistance to mechanical wear;
Compatibility with R-65 rails and M24, M27 joint bolts;
Compliance with Ukrzaliznytsia requirements and international standard EN 13674-1.

Supply and delivery

Supply of complete R-65 insulated joint sets: 2 fishplates, 4 insulating pads, 4 bushings, bolts, nuts, and washers;
Each batch is tested for insulation resistance, profile accuracy, and coating quality;
Reinforced versions available for sections with increased loads;
Delivery across Ukraine by road or rail from the warehouses of “Prombudkoliya”.
