Straight through cold-applied shrinkable EPDM cable joints designed for high stress medium voltage EPR cables

The introduction of high electrical stress EPR insulated medium voltage cables leads to the development of new cable joints suitable for installation. This paper presents the joint design considerations and test data. The test program is based on IEEE Standard 404-1993. Test samples include joints for high stress EPR cables and transition joints from high stress EPR cables to PILC cables. All test results have shown that both joint designs comply with the IEEE standard and suitable for operation in cable network systems.
