2025-09-06 What is oil-filled cable?Oil-filled cable is characterized by low-viscosity insulating oil filled into the cable insulation. The oil supply maintains a constant pressure to eliminate air gaps within the insulation. It is a representative product of "pressure-type" wire. It is primarily used in high-voltage (110 kV
