DIN EN 60684-3-283:2011-09

This International Standard is part of a standard series dealing with insulating sleeving for electrical purposes. The series "Flexible insulating sleeving" consists of three parts: - Part 1: Definitions and general requirements (IEC 60684-1); - Part 2: Methods of test (IEC 60684-2); - Part 3: Specifications for individual types of sleeving (IEC 60684-3). This part is one of the sheets which belong to Part 3: Sheet 283: Heat-shrinkable polyolefin sleeving, for bus-bar insulation. This standard gives the requirements for two types of heat-shrinkable, polyolefin sleeving for bus-bar insulation, with a 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 sleevings cover a significantly large range of sizes and wall thicknesses, Tables A.1 and A.2 provide guidance to the range of sizes available. The actual size and wall thickness shall 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 standard meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this standard alone. The responsible Committee is K 181 "Feste elektrische Isolierstoffe" (AK 181.0.5 "Isolierschläuche") ("Solid electrical insulating materials" (WG 181.0.5 "Insulating sleeving")) of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
