Abstract

This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2019-05-17 to 2019-06-28. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.

IEC 60684-3-283: 2019 gives the requirements for two types of heat-shrinkable, polyolefin sleeving for bus-bar insulation, with a nominal shrink ratio of 2,5:1. This sleeving has been found suitable up to temperatures of 100 °C.
Type A: Medium wall – internal diameter up to 170,0 mm typically
Type B: Thick wall – internal diameter up to 165,0 mm typically
These sleevings are normally supplied in colour, red or brown. Since these types of sleeving cover a significantly large range of sizes and wall thicknesses, Annex A (Tables A.1 and A.2) provides guidance to the range of sizes available. The actual size and wall thickness will be agreed between the user and supplier depending on the electric strength of the installed tubing offered and the requirements of the user. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This second edition cancels and replaces the first edition published in 2010 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a. change of moulded plaque thickness for resistance to tracking and weathering tests to (6 ± 0,5) mm.
Keywords: Heat-shrinkable, polyolefin sleeving for bus-bar insulation
