The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1) Part 2: Methods of
22、 test (IEC 60684-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard comprises one of the sheets of Part 3 as follows: Sheet 281: Heat-shrinkable, polyolefin sleeving, semiconductive BS EN 60684-3-281:2010 6 60684-3-281 IEC:2010 FLEXIBLE INSULATING SLEEVING Part 3:
23、 Specifications for individual types of sleeving Sheet 281: Heat-shrinkable, polyolefin sleeving, semiconductive 1 Scope This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, semiconductive, with a nominal shrink ratio of 3:1. This sleeving has been fou
24、nd suitable up to temperatures of 100 C. Type A: Thin wall Internal diameter up to 195,0 mm typically Type B: Medium wall Internal diameter up to 120,0 mm typically These sleevings are normally supplied in the colour black. Since these types of sleevings cover a significantly large range of sizes an
25、d wall thicknesses, Tables A.1 and A.2 in this standard provides guidance to the range of sizes available. The actual size shall be agreed between the user and the supplier. Materials which conform to this specification meet established levels of performance. However, the selection of a material by
26、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 specification alone. This sleeving is designed to be used in MV cable accessories and as such electrical performance must be proven as part of the
27、 assembly. Examples of this are described in HD 629 and IEC 60502 series. 2 Normative references The following referenced documents are indispensable for the application of this document.
