EN 61395:1998

• Abstract:

  Is applicable to non-interrupted creep-testing of stranded conductors for overhead lines such as those specified by IEC 61089. Procedures for interpreting the results are also included. The object of the test is principally to calculate creep for any purpose and to compare creep of different conductors.

Overview

EN 61395:1998 (adopted as SIST EN 61395:1999) is a CLC/European standard for overhead electrical conductors that defines creep test procedures for stranded conductors. It is applicable to non‑interrupted creep‑testing of stranded conductors used on overhead power transmission and distribution lines (see IEC 61089 for conductor types). The standard includes procedures for interpreting test results with the principal objective of calculating creep and comparing creep behaviour between different conductors.

Key Topics

• Scope and application: Applies to non‑interrupted creep testing of stranded conductors for overhead lines; intended for conductors referenced by IEC 61089.
• Creep measurement focus: Procedures to obtain time‑dependent elongation (creep) data and to calculate creep values for comparison.
• Result interpretation: Methods for analysing test data so that creep of different conductor constructions can be compared reliably.
• Standard identification: Published as EN 61395:1998 and adopted in Slovenia as SIST EN 61395:1999 (ICS 29.240.20 - Power transmission and distribution lines).
• Multilingual recognition: Title and scope published in multiple languages (English, Slovenian, German, French), reflecting its European adoption.

(Note: the standard’s scope and objectives are described here; specific test parameters, sample preparation, apparatus, durations and acceptance criteria should be taken directly from the official document.)

Applications

EN 61395 is practical for professionals and organizations involved in the design, testing and procurement of overhead conductors:

• Conductor manufacturers - to assess long‑term dimensional stability and to compare product variants.
• Independent testing laboratories - to perform standardised creep tests and deliver comparable results to clients.
• Utilities and transmission system operators - to evaluate conductor performance, lifecycle behaviour and suitability for specific line projects.
• R&D teams and material scientists - to validate new alloys, strand geometries or core materials against established creep behaviour criteria.
• Standards and compliance engineers - to reference a recognised European procedure when specifying acceptance testing.

Related Standards

• IEC 61089 - standard for stranded conductors for overhead lines (referenced for conductor types).
• Other regional or international standards on overhead conductor testing and mechanical performance may be consulted alongside EN 61395 for comprehensive evaluation.
