To raise the safety level of railway operations at source and move the industry towards higher quality and higher standards, the National Railway Administration has recently formally issued two batches of railway industry technical standards, several of which bring significant revisions and additions to the technical specifications for OCS materials and equipment.
A dense round of OCS standard updates
Within the standards system released this time, the OCS field has seen a dense round of technical specification updates. The newly developed and revised standards cover technical requirements, test methods and inspection rules for key components ranging from contact wire and stranded conductors to preformed fittings, further tightening the quality and safety threshold for railway OCS equipment.
Four standards in particular have drawn wide attention across the OCS industry:
TB/T 2075.24-2026, Electrified Railway OCS Components, Part 24: Preformed Fittings
TB/T 2809-2026, Electrified Railway OCS: Copper-Alloy Contact Wire
TB/T 3111.1-2026, Electrified Railway OCS, Stranded Conductors, Part 1: Copper and Copper-Alloy Stranded Conductors
TB/T 3111.2-2026, Electrified Railway OCS, Stranded Conductors, Part 2: Aluminium Conductors with Aluminium-Clad Steel Core
Key points of the upgrade
The main directions of this revision are precise control of material chemical composition, higher mechanical performance targets, improved fatigue life test methods, and standardised product marking and traceability information. The new standards impose stricter requirements on the reliability and durability of key OCS components.
Opportunities and challenges for manufacturers
As a manufacturer focused on the development and production of railway OCS products, Henan Chuangwit Railway Equipment Co., Ltd. is actively tracking and studying the technical requirements of the new standards, and has laid out R&D and production line upgrades in advance to ensure that its products meet the new rules. The company has comprehensive testing equipment and a sound quality management system, and is able to carry out product verification and improvement work against the new standards.
Henan Chuangwit Railway Equipment Co., Ltd. will continue to apply its technical strengths to supply the railway industry with high-quality OCS products and services that comply with the latest standards. For technical consultation or business cooperation, please call 0375-6051688.
