An oil-filled high voltage electric cable line incorporates a filter in an external cooling duct which interconnects the opposite ends of a cable run and also incorporates a pump for forced circulation of the oil through the cable and a heat exchanger to effect the cooling. The filter comprises two metal meshes 15, 20 with the hollow space between filled with adsorbent material 30 and a filter paper 29 lining the mesh 15. Oil entering at 33 passes through mesh 20, material 30, filter paper 29 and then mesh 15 before issuing at 34. The meshes remove the larger particles and the adsorbent material removes the smaller particles or powders from the cable oil. <IMAGE> |
