This standard is applicable to heat shrinkable medium voltage moulded shapes in a range of configurations suitable for insulation, environmental sealing, mechanical protection, strain relief for power cable terminations, joints and stop ends. These moulded shapes have been found suitable for use for temperatures between -40ºC and 100ºC. The moulded shapes may be supplied with a pre-coated adhesive. A guide to adhesive compatibility and temperature performance is given in Appendix A. Refer to the manufacturers/suppliers for options. 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 specification alone. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and as such electrical performance must be proven as part of the assembly. Examples of this are described in EN50393, HD 629 and IEC 60502.
