IEC 62917-2016 PDF

Full title and description

Railway applications - Fixed installations - Electric traction - Copper and copper alloy grooved contact wires. This International Standard specifies the product characteristics, test methods, verification procedures and ordering/delivery conditions for copper and copper-alloy grooved contact wires used in overhead contact lines (nominal cross-sections from about 70 mm² to 170 mm²).

Abstract

IEC 62917:2016 defines mechanical and electrical characteristics, material designations and standardised profiles for grooved contact wires used in electric traction overhead systems. It includes specification of resistivity and tensile requirements, test methods, inspection/verification procedures, a designation system and annexes with standardised configurations, common alloy compositions and national deviations.

Scope

IEC 62917:2016 applies to copper and copper-alloy grooved contact wires intended for overhead contact lines in railway electric traction. The scope covers nominal cross-sections in the range approximately 70 mm² to 170 mm² and sets out required product characteristics, permissible materials, profile/configuration dimensions (including clamping groove types), electrical and mechanical property limits, test procedures, verification checks and ordering/delivery conditions. Annexes give standardised configurations, common alloy compositions and informative national deviations.

Key topics and requirements

• Definition and designation system for grooved contact wires (naming convention including material, strength and conductivity requirements).
• Permitted materials: copper and selected copper alloys (material designations and recommended compositions; environmental note discouraging cadmium-containing alloys).
• Standardised profile configurations and nominal cross-sections (types A/B and annexed national profiles for some countries).
• Mechanical requirements: tensile strength/minimum breaking load, appearance and dimensional tolerances, joint area requirements.
• Electrical requirements: limits for resistivity/maximum resistance per km and minimum conductivity (% IACS) at 20 °C.
• Specified test methods and verification procedures for resistivity, tensile testing, reverse-bend (flexibility) and other checks (references to ISO/IEC test methods where applicable).
• Ordering and delivery conditions, marking, packaging and inspection criteria.

The standard also contains informative annexes with alloy tables, physical properties and special national conditions.

Typical use and users

This standard is used by railway infrastructure owners and operators, overhead line designers and engineers, contact-wire manufacturers and suppliers, procurement teams specifying material and profile requirements, testing laboratories performing verification and acceptance tests, and national standards/rail authorities referencing international requirements for electric traction overhead systems.

Related standards

IEC 62917 references or is used alongside other test and material standards (examples include IEC/ISO test methods and material test standards such as IEC 60468 (resistivity measurement methods), ISO 6892-1 (tensile testing), ISO 7801 (wire reverse-bend test) and national/EN documents for specific alloy designations). It is produced under IEC TC 9 (electrical equipment and systems for railways) and complements other railway electrical and overhead-line standards.
