23、um voltage joint insulation 1 Scope This part of IEC 60684 gives the requirements for heat-shrinkable sleeving for medium voltage joint insulation, with a range of shrink ratios. This sleeving has been found suitable up to temperatures of 100 C. These sleevings are normally supplied in colour, red o
24、r brown. Since this type of sleevings covers a significantly large range of sizes and wall thicknesses, the actual size will be agreed between the purchaser and supplier. Materials which conform to this standard meet established levels of performance. However, the selection of a material by a user f
25、or 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 medium voltage cable accessories and as such electrical performance will be proven as part of the
26、assembly. Examples of this are described in HD 629 and IEC 60502. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
