24、(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 60684-3-281:2010Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 21/04/2011

26、efin sleeving, semiconductive, with a nominal shrink ratio of 3:1. This sleeving has been found 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 t
27、he colour black. Since these types of sleevings cover a significantly large range of sizes and 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 s
28、pecification 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 specification alone. This sleeving is designed to be
29、used in MV cable accessories and as such electrical performance must be proven as part of the 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. For dated reference
