MV-105 4/0 AWG 35 kV 133 % EPR
Nominal calculation, not one manufacturer's datasheet. The conductor is NEC Chapter 9 Table 8; the walls are the ICEA nominals as Okonite and Southwire reproduce them, the screens and the jacket the values six makers print or give through their diameters, because UL 1072 and ICEA S-93-639 were not read. Check the datasheet before you specify or order.
By NEC Table 8 and the catalogued walls, MV-105 4/0 AWG 35 kV 133 % EPR comes to an overall diameter of about 41.4 mm and a weight of about 2,690 kg/km.

MV-105 is the UL 1072 medium voltage cable of NEC Article 311, here as a single copper conductor or three with a ground: an extruded strand screen, EPR insulation at the wall of its class and level (100, 133 or 173 %), an extruded insulation screen, a 5 mil copper tape at 25 % overlap and a PVC jacket; the three-conductor cable lays three such cores with a bare copper ground in an interstice, fillers and a binder tape under its jacket. MV-90 has the same walls. Checked against Southwire, Okonite, Prysmian, AmerCable, LS Cable and Priority Wire: research/designer-americas/mv105.md in the site repository.
