Submit a request

Insulated joint fishplates R-50 are railway track components designed for the mechanical connection and electrical insulation of R-50 rails. They are used to create insulated joints in automatic block systems, automatic locomotive signalling, and electric interlocking systems.

Description and design

R-50 insulated fishplates are manufactured in accordance with DSTU 8790:2018 from structural steel with integrated electrical insulation elements. The design consists of two profiled steel fishplates with insulating pads and bushings installed between them. This configuration prevents metal-to-metal contact and ensures complete electrical separation of adjacent rail sections.

The fishplate geometry matches the R-50 rail profile;
Pads are made of fiberglass laminate, polyamide, or PTFE (fluoroplastic);
Bushings for joint bolts provide reliable insulation under compression;
Metal components are coated with anti-corrosion and insulating compounds;
The product is suitable for operation in all climatic zones.

Application

R-50 insulated fishplates are used on railway lines equipped with electric interlocking, automatic block, and signalling systems. They are installed at rail circuit separation points, providing electrical isolation of adjacent sections while maintaining the mechanical strength of the joint.

Advantages of R-50 insulated fishplates:

High mechanical strength and reliable rail joint fixation;
Complete electrical insulation under high humidity and vibration;
Durability and resistance to temperature fluctuations and corrosion;
Compatibility with standard M24 and M27 joint bolts, washers, and pads;
Compliance with the technical requirements of Ukrzaliznytsia and DSTU 8790:2018.

Supply and комплектation

Supply of complete R-50 insulated fishplate kits (2 fishplates, 4 pads, 4 bushings, bolts and washers);
Each product is tested for insulation resistance and geometric accuracy;
Optional enhanced anti-corrosion coating available;
Delivery across Ukraine by rail or road transport from Prombudkoliya warehouses.
