TECK90 3C 12 AWG 600 V
Nominal calculation, not one manufacturer's datasheet. The conductors are NEC Chapter 9 Table 8; the RW90 walls, the bond, both jackets and the armour band are the values seven makers print or give through their diameters, because CSA C22.2 No. 131 was not read. Check the datasheet before you specify or order.
By NEC Table 8 and the catalogued walls, TECK90 3C 12 AWG 600 V comes to an overall diameter of about 19.0 mm and a weight of about 350 kg/km.

Each layer's cross-section times its density; stranded conductors, laid-up cores and helical wires count 2 % longer than the cable. Densities: copper 8.89 and aluminium 2.703 g/cm³ (the values of IEC 60028 and IEC 60889); XLPE 0.92, PE 0.94, PVC 1.45, semicon 1.12, steel 7.85 g/cm³ (usual compound values).
