The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1) Part 2: Methods of test (IEC 60684-2) Part 3: Specificatio
27、ns for individual types of sleeving (IEC 60684-3) This standard comprises one of the sheets of Part 3: Sheet 283: Heat-shrinkable, polyolefin sleeving for bus-bar insulation.

28、 SLEEVING Part 3: Specifications for individual types of sleeving Sheet 283: Heat-shrinkable, polyolefin sleeving for bus-bar insulation 1 Scope This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin sleeving for bus-bar insulation, with a nominal shrink ratio of
29、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
30、 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
31、 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 should be based on the actual requirements necessary for adequate performance in that application and not based on this specifica
32、tion alone. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
