Approximately 50 per cent of the rectifiers were used for rail-
way electrification in the Urals, the Caucasus, and the Moscow
metro. These were of the 3300 volt type. The other 50 per cent
were used by electrolytic plants. Large aluminum plants were
located at Zaporozhye on the Dnieper and at Murmansk. The latter
was completed about 1951 after it had been under construction for
about two years. A zinc plant was located at Chelyabinsk. There
were two copper refineries near Sverdlovsk.
A Yew
rectifiers were also sent to address, out the destination
another
and number is not known . These were of the low-voltage higI50
current (1 . e . , . e le ctro lysis ) type. This shipment constituted no
special order, but was considered 41qutine. .
No purchasing representatives ever came to Zavod 659. Government
representatives from MosCow visited the plant two or three times
per year. The purpose usually seemed to be to discuss material
shortages. production problems, etc.
Most of the copper was obtained locally--very pure copper was
procured from Moscow. A lowzgrade porcelain came from about 100
kilometers from Sverdlovsk LKomissulaphonetig. A better grade
came from Leningrad. Insulating Materials were made at Zavod 659.
Mercury was obtained from the Ural region. Relays and contacts
were shipped from Kuybyshev; condensers and thermocouples, from
Moscow.
