The arrangement is such that there is no appreciable inter-ference between circuits due to magnetic action in the iron cores of thedifferent coils or to the necessarily close electrical relation in thewindings. The loading coils are potted and sealed in iron pots, two of whichare shown in Fig. 16, and in the country these are mounted on polefixtures. Each pot contains 36 groups of 3 coils each.

The pots can be obtained in different sizesdepending upon the number of coils which it is desired to install atone time. When the cable was installed, extra lead sleeves were Papers by M. I.

The loading pointsmust be uniformly spaced in order to obtain the proper impedancecharacteristics in the circuits as will be referred to later.
