ABSTRACT:
An oil-filled electric cable installation, in which oil when flowing outwardly from the cable to a pressure-maintaining oil tank it passes through a percolating filter, preferably of an active material, to remove particulate and/or dissolved impurities. A one-way return passage bypasses the filter so that maintenance of pressure is not impaired, and if required a high-pressure bypass may be used to protect the filter from unusually high pressures.
