What is BS EN IEC 61854 about?
BS EN IEC 61854 discusses about overhead line requirements and tests for spacers which enables stability and operability of overhead lines during chaotic weather conditions. BS EN IEC 61854 applies to spacers for conductors bundles of overhead line. BS EN IEC 61854 covers rigid spacers, flexible spacers and spacer dampers.
BS EN IEC 61854 covers the line design practices and spacers most commonly used at the time of writing.
Note: BS EN IEC 61854 does not apply to interphase spacers, hoop spacers and bonding spacers.
Who is BS EN IEC 61854 for?
BS EN IEC 61854 on overhead lines for spacers is useful for:
- Manufacturing of overhead line spacers
- Companies dealing with overhead electric wire spacing
- Retailers and suppliers for overhead line spacers
Why should you use BS EN IEC 61854?
Overhead line spacers are a product which adds reliability and protection to the conductor bundle, by separating the conductors and preventing them from clashing under operating conditions.
BS EN IEC 61854 provides you information for various types of spacers such as: rigid spacer, flexible spacer, spacer systems, high temperature conductors (HTC) and maximum continuous operating temperature, which helps in safety of conductors and manufacturing of spacer for overhead lines in a secured way.
As a user of BS EN IEC 61854, you will be able to assess the quality and performance of spacers by testing method which can be routinely maintained and calibrated.
What’s changed since the last update?
BS EN IEC 61854:2020 supersedes BS EN 61854:1998, which is withdrawn. It includes:
- Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties
- Specify as far as possible test parameters and acceptance values; Avoid as far as possible the alternative procedures for the same test and introduce a simpler test device for the simulated short circuit current test
- Introduce test at low temperature on fastener components such as break away bolts and conical spring washers and prescribe a different procedure for sub span oscillation tests on spacers equipped with clamps having rod attachments
- Modify the test procedure for the aeolian vibration tests and prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments
- Re-edit all the figures in order to make them clearer and more homogeneous and introduce an additional test device for the simulated short circuit current test
