Gtcenroa - RLxGS In selecting*a-drum to ship electrical grade Arcelor, v:e should consider two problem i 1, Hovs can \$e provide the very best electrical properties to the .euetotsar on rec^pt of the Gruuu 2. SiO\v can we avoid drum darjago, leakage and so forth clurins chipaent. Of these two, problem l io by far the roost unresolved. Problem #1 not only involves tho proper eoloctiou of a driua, but also the tochaiqus tie use inalenvilng and pry- paring: the c3run for filling pith elec tried grade Arcelor, fhas v.o noed a cuore lining which will protect the electrreul properties during Khlprrni; but of . pc .0 1 ; 'w-hr., v;e iuisi develop better toouniques for ior-nir;-; tie cor prior to filling, Hr, lentgnus feels that the real advantages which Pro-delac and Layer Lave in delivering tetter electrical propex'fcies are gainsd through bettor cleaning of the drag ~ in addition to Laving more efficient protection against deterioration of electrical properties after the material is placed into the drums. ' ^ So the question bee discs how to accomplish this most economically. Car rooojhcondafcions would Include the following: 1. concentrate on obtaining a drum which .would provide maximum protection of the electrical properties of the Aroclor during rhipossnt. lie don't cars how you do this - through phenolic linings or by using a galvanised drum or some other technique. 2. develop the very best techniques for cleaning the drum . prior to filling, Regardless'of the selection of drum, to protect the electrical properties curing rhipusiit, it mat he thoroughly cleaned and flushed vi th good quality Ar-oelor in order to rehe certain that the material then placed in the drum will retain the hoot electrical properties which wo are able to produce.

C Carder ~2- heecnvbor i, 3- kt the present time v;e are 120re inter-eated in piotocting the electrical properties than so are in going from an 13 gauge drum to a 15 gauge drum SJiia latter 1rove tjould provide added protection against Oran damage, leaisgo and no forth5 bat this problem in not as serious a& that of protecting the electrical properties during shipment. With these objectives in Mna, can you give us a progress report on the work vlrich you rave'done toward the proper selec tion and cleaning of drums for shipment of capacitor Ar-ocior. /,i -C C. It.
