Описание (английский):

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.

Abstract

Overview

Key Topics

Scope and Application Applicable to uninterrupted creep testing of stranded conductors used in overhead lines to determine time-dependent permanent elongation under load.
Normative References Principally refers to IEC 61089:1991, which describes round wire concentric lay overhead electrical stranded conductors.
Definitions
- Sample Length: The total length of conductor between the test end fittings.
- Gauge Length: The specific length segment where creep elongation is measured.
- Test Temperature: Average temperature measured at several specified points along the gauge length during testing.
- Test Load: Constant mechanical load applied during creep testing causing elongation over time.
Instrumentation and Calibration Requirements for accurate units, temperature measurement devices, and calibration methods are included to ensure precise and reproducible testing conditions.
Sample Preparation Guidelines for selecting conductor samples and preparing them for testing to minimize variability in results.
Temperature Control Procedures to monitor, measure, and compensate for temperature fluctuations affecting creep measurements, crucial since temperature influences material behavior.
Load Application Specification of the constant test load to simulate real-world stress conditions on overhead conductors.
Test Procedure Step-by-step instructions on conducting creep tests under controlled conditions, including the duration and recording of elongation data.
Data Acquisition and Interpretation Emphasizes systematic data collection for elongation over time and outlines methods for interpreting the creep results for comparison and evaluation.

Applications

Quality Assurance in Overhead Line Manufacturing Ensures that electrical conductors meet mechanical performance criteria to withstand long-term loading without excessive deformation.
Comparison of Conductor Designs Allows manufacturers and utilities to assess creep behavior differences between various stranded conductor constructions to select optimal designs.
Performance Prediction Provides critical data for estimating conductor behavior under sustained loads, supporting the design and maintenance planning of overhead lines.
Research and Development Supports material science and engineering advancements by providing standardized test methods to evaluate new conductor materials and configurations.
