The cable consists of three main parts: Conductor, Insulation, Protective Sheath.

Why is there oil in the cable?

These tubular cables are oil filled at nominal low, medium and high pressure. Higher voltages require higher oil pressures to prevent the formation of voids within the cable insulation that allow partial discharge.

Does a 1960s house need to be rewired?

Unless wiring is modern PVCu coated type May need rewiring. If you see any old rubber insulated cables, fabric insulated cables (used until the 1960s) or lead insulated cables (1950s) then it needs to be replaced because the insulation will crack.
