All transformers produced by TRA;RO are for the range from 1 to 110 kV;
transformers with higher voltage ranges have not been produced. The
automatioally-oontrolled transformers are equipped with special control
installations (Spesialreggelwerk) and can be adjusted to 21 ranges. 25X1

Ih addition, about 40 transformers from 750 to 319500 IVA were overhauled
in the enterprise during 1954. #,otal value of transformer production

This amount corresponds to the year pduotion capacity of the enterprise.
4- About 2596 of the entire transformer production is for export, mainly to the
USSR and satellite countries. Twenty to 25 percent is for "indirect export'",
i-91-for East German enterprises which are sxizl~ equipment in which the
TR~~RO transformers are used as parts. The remainder goes to East German
industry. During 19549 the following exports were carried out to Soviet
Bloc countries:
a. 251 small net transformers from 5Q to 29500 kVA with imp** voltage
(Oberspannung) from 6 to 30 kY(to tbs USSR). In addition, spare
windings for 25 large traneform'itM.were delivered to the USSR in 19540
These large transformers of 16 t1.5 MVA with 110 KY input voltage
had been previously delivered to the USSR (in 1952 and 1953).
bo Four large transformers of 31o5 MYA, 110 KY with automatio-oontrol
installation for 21 ranges (to Poland).
cc 12 large transformers from 16 to 25 MVA, 110 KY with automatio>oontrol
installations for 15 to 21 rang" (to China)0
d. One mobile transformer (Wandertransformator) of 31.5 MVA, 110 KY9 and
two mobile transformers of 25 MVA, 110 KV (to Czechoslovakia). These
transformers were equipped with automatio'oontrol installations for
21 ranges.

delivery, in 1955, of two :Large generators of 50 MYA? 110 KV, with
control installations for 21:ranges, and for two large transformers of
105 MVA, 110 KY9 with special cooling equipment. Since the Dresden
enterprise was not able to produce the latter two machines, the order
was transferred to VEB Traneformatorenwerk Oberspree (TRO), Berlin.

a strong tendency to decrease, probably as a-result of the "new line" limiting

11. Following are the most important enterprises delivering to TRARO Dresden
the materials needed for the production of transformers,
a.* VEB Kabelwerk Oberepree Berlin and V!EB Messing- and Kupferwerke -
Hettatedt deliver profile copper wire for the transformer windings.
The most important profiles are 3 by 5; 3,by.12; 4 by 5 and 4 by 6

The wrapping consists of 39 6, 9 and 12 layers aoe0rding to the
insulation strength required, TRARO has a monthly requirement of about
150 tons of copper wire;
b0 VEB Sohichtpres ffwerk Dresden and VEB ISOKOND in Berlin-Weissensee
deliver the hard-pager cylinders upon which the copper wire is wounds
lifter winding, which is done at TRARO the cylinders are soaked with a
shellac-phenol solution and vacuum-dried;
co VEH Papierfabrik Wolfewinkel near Eberswalde delivers cable insulation
paper for the wrapping of the copper wire and for the insulation of
unprotected parts of the transformers. Deliveries from this enterprise
are not sufficient for TRARO demands. The lack of suitable cable
insulation paper represents one of the most serious bottlenecks in
East German transformer production. The research and development
department of TRARO is therefore working on the development of
substitute material;
d. VEB Blechwalzwerk Olbernhau delivers transformer sheet metal. The only
other East German enterprise able to produce suitable sheet metal for
transformers, VEB Vkpenhuettenwerk Thale, is the main delivery firm for
VEB TRO, Berlin. The Olbernhau enterprise cannot cover the demand of TRARC
