The density is used to calculate the mass of the cable which is used for cable pulling calculations.

- High and extra-high temperature insulation materials EVA, SiR and ETFE, FEP, PTFE and PFA: Leoni LEOMER 'Insulation material properties'
- PPLP: contains paper (0.85), PP (0.91) and oil/rosin (1.05) in case of mass impregnated HVDC cables so the value is expected to be around 0.9. In case of HVAC PPLP cables, which is not common anymore, mineral oil (0.88) is used and the value will be lower.

the insulation is made of kraft paper with 0.75 g/cm3 and contains about 50% of the volume impregnating fluid. For oil impregnated (SCOF) cables mineral oil with 0.88 g/cm3 is used and for mass impregnated oil/rosin with higher viscosity and 1.05 g/cm3 is used.
