Overview

EN 62621:2016/A1:2016 - Railway applications - Fixed installations - Electric traction - Specific requirements for composite insulators used for overhead contact line systems is a CENELEC (CLC) amendment that updates the 2016 European standard for composite insulators in railway overhead contact lines. The amendment (A1) replaces Annex ZZ and clarifies the standard’s relationship with EU Interoperability Directive 2008/57/EC and the TSI “Energy” (Regulation (EU) No 1301/2014). It applies to design, testing and assessment aspects that affect the safety, interoperability and performance of overhead contact line systems.

Key Topics and Requirements

The standard focuses on specific technical and quality aspects for composite insulators without prescribing national deviations. Key topics include:

• Material and manufacturing requirements for composite (polymeric) insulator components to ensure long-term performance.
• Mechanical performance: load-bearing capability, mechanical strength and durability under operational stresses.
• Electrical properties: insulation integrity, flashover considerations and behaviour under traction voltages.
• Environmental and ageing resistance: performance under pollution, UV exposure, humidity and temperature cycling.
• Geometry and dimensional requirements relevant to overhead contact line geometry and clearances.
• Current collection quality and dynamics: influence on mean contact force, dynamic behaviour and quality of current collection between pantograph and catenary.
• Technical compatibility and interoperability: requirements to ensure insulators are compatible with fixed installations and rolling stock parameters.
• Assessment and verification procedures: criteria for particular assessment of the overhead contact line as an interoperability constituent (referenced in Annex ZZ).

Note: The amendment explicitly links clauses of EN 62621 to the essential requirements of Directive 2008/57/EC for the Energy subsystem.

Applications

EN 62621:2016/A1 is used to:

• Specify technical requirements in procurement documents for overhead line insulators.
• Guide manufacturers on design and testing expectations for composite insulators.
• Support conformity assessment and certification related to rail system interoperability.
• Inform maintenance rules, inspection criteria and asset management decisions for overhead contact line systems.

Who Uses This Standard

• Railway infrastructure owners and asset managers
• Overhead contact line designers and system engineers
• Insulator manufacturers and component suppliers
• Testing laboratories and conformity assessment bodies
• Procurement officers and regulatory authorities working on rail interoperability

Related Standards and Regulations

• EN 62621:2016 (base standard)
• Directive 2008/57/EC - Rail Systems: Interoperability
• TSI “Energy” - Regulation (EU) No 1301/2014
