25、edium voltage cable jointing and termination applications, with nominal shrink ratios of up to 3:1. These sleevings have been found suitable for use up to temperatures of 80 C. Type A: polyolefin based. Type B: fluoropolymer based, enhanced oil resistance. These sleevings are normally supplied as tr

26、anslucent. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A, Tables A.1 and A.2, in this document, provide a guide to the range of sizes available. The actual size will be agreed between the purchaser and supplier. Materials which conform to thi

27、s 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. This sleeving is designed to be used in

28、 MV cable accessories and as such, electrical performance as defined as part of the assembly. Examples of this are described in HD 629 and IEC 60502 series. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
