Insulated rail joint R-50 — a set of components designed to create insulated joints for R-50 rails in railway automatic block, electric interlocking, and signaling systems. It ensures high mechanical strength of the joint while providing complete electrical isolation between adjacent track sections.

Description and design

The R-50 insulated rail joint set is manufactured in accordance with TU U 25.2-31236182-005-2004 and includes steel fishplates, electrical insulating pads, bushings, and fasteners. The fishplates are made of 09G2S steel and coated with an insulating compound. Insulating pads made of fiberglass laminate, PTFE (fluoroplastic), or polyamide are installed between the metal elements, eliminating metal-to-metal contact. The design maintains its insulating properties under prolonged dynamic loads and harsh climatic conditions.

Fishplate profile fully соответствует the R-50 rail section;
Insulating bushings prevent electrical contact between bolts and fishplates;
Insulating pads feature high mechanical strength and moisture resistance;
Protective coating of metal parts provides corrosion and weather resistance;
Guaranteed insulation resistance of at least 10 MΩ at humidity up to 98%.

Application

The R-50 insulated rail joint is used on railway lines equipped with signaling, automatic block, and electric interlocking systems. It is installed at rail joint locations to electrically separate track circuits. Suitable for station areas, open line sections, and turnouts.

Advantages of the R-50 insulated rail joint:

High mechanical strength while maintaining electrical insulation;
Long service life and resistance to vibration and temperature fluctuations;
Reliable performance under high humidity and dusty conditions;
Compatible with R-50 rails and M24/M27 joint bolts;
Full compliance with Ukrainian Railways requirements and railway safety standards.

Supply and configuration

We supply complete R-50 insulated joint sets: 2 fishplates, 4 insulating pads, 4 bushings, bolts, nuts, and washers;
Each batch is tested for insulation resistance and profile geometry accuracy;
Reinforced versions available for sections with increased loads;
Delivery across Ukraine by rail or road transport from Prombudkoliya warehouses.
