Zusammenfassung:Design of current lead boxes and joint boxes for 2.5 km long St. Petersbubrg HTS DC cable project (2.5 kA, 20 kV) is described. Maximum internal pressure of sub-cooled nitrogen is 1.4 MPa. Both current lead boxes and joint boxes are equipped with terminals for temperature and pressure measurements. Current leads of different polarities have independent electrical insulators. Two current lead boxes and one joint box have been preliminary tested. The first test results are reported.
