Characteristics of Oil-Filled Cable

This paper deals briefly with the general theory and some of the outstanding characteristics of oil-filled cable practise. Oil-filled cable has had a perfect operating record during the past four years and during this time many simplifications and economies have been introduced. Further gains in this direction are indicated. Today, this type of cable is well in line with ordinary paper-insulated cable from an economic standpoint. The limiting features of oil demand and oil supply are explained and typical methods of oil feed with expansible reservoirs described. Space does not allow the inclusion of many additional things of interest such as a description and drawings of the complete line of cable and accessories that have been developed.
