Medium voltage (MV) power cable systems rely not only on the quality of the cable itself, but also on the performance of accessories such as joints and terminations. Among the available technologies, cold shrink joints have become a preferred solution for XLPE insulated MV cables due to their reliability, installation safety, and long-term performance. Let’s explore the role of cold shrink joints in MV cable systems and how they comply with the requirements of IEC 60502-4.
Cold shrink joints are pre-expanded elastomeric cable joints that shrink to their original size after the removable inner core is extracted. Unlike heat shrink technology, cold shrink joints:
IEC 60502-4 specifies the requirements and test methods for accessories used with power cables rated from 6 KV to 30 KV (Um = 7.2 KV to 36KV), including:
For cold shrink joints to comply with IEC 60502-4, they must pass strict type tests and routine tests, such as:
