1400 KV TRANSMISSION LINE
1
The Kuibyshev-Moscow 1400 kv transmission line is approxisrately
560 miles long, the longest of its kind in the world. Designed to
deliver 6.1 billion kurh of energy annually from the Kuibyshev hydro-
electric plant to Moscow, the line constitutes an L port:ant link in
the power system that serves the European part of the USSR. It is also
the first 400 kv system in the USSR.
Collateral material reports that construction of the transmission
line began in April 1952, and that it was completed and put into
operation in May 1915'. it is a double.circuit l ne carried by two
parallel rotes of toT,ers. with each circuit carrying half the full cap-
acity of the line.
Three s :ni tching stations divide the line into four sect-1-ions. These
stations are reported to be constructed along the route of the transmission
line at Ulyanovsk, Ar was, and at Vladimi . The lf_-e terra. inates in the
vicinity of Moscow in two substations: one near Noginsk (55c.5,11,1-
38028'E),, the second in &.,skudnikovo (550531N-37 ?-, 4'E ) . As the power line
consists of two separate circuits, the southern and the northern, each
is connected to the 400 kv East Substation at Noginsk while the north
circuit continues to the 400 kv North Substation at Reskdn=ikovo, 35
miles west of Noginsk.

The accompanying map shows 110 miles of the 56,0-.mile Kuibyshev-
Moscow 400 kv transmission line, covered by and confirmed by
photography. This includes 50 miles of the line southeast of
Vladimir covered by oblique photography which allows only an approxi-
mate location. Heavy cloud cover prevents continuous location of the
Moscow-end of the line.
The two parallel circuits which form this transmission line are
first discernible on the photography east of Moscow near the town of
Pavloskiv Posad, and approximately 11 miles east of the substation near
Noginsk. From here the two circuits continue in a ENE direction to-the
small village of Rukav, located 7.5 miles southwest of Vladi..m-;,:?. At
Rukav the lines lead into a large switching station which on
photography appears to be under construction. From this station the
two circuits are discernible on oblique photography only, and continue
in a general southeasterly direction for about 50 -miles where all photo-
graphic coverage of the transmission line ends. The line is reported to
cross the Oka River in the vicinity of Morom.
The spacing of the towers in each of the twc parallel circuits
ranges from. 1300' to 1500' except in the case of a major tea?rain feature
such as a large river or hill. The clearing in wooded areas is approx-
imately 200' wide for each circuit. The two parallel clearings are
about )1 J ' apart.
Each tower appears to consist of two, narrow, tapered, steel lattice
masts supporting at the top a lattice cross arm from which are suspended
the insulators and individual power conductors. Height of the towers
as determined from aerial photography is The width of the cross-arm

at the top, the widest part of a tower, is approximately - The spacing
between the two masts of a tower is -
On some of the photography, the towers appear to be supporting three
large lines. This tends to substantiate reports that each transmission
circuit is a three--phase line and that each phase of. the line contains
three conductors located at the apexes of an equilateral triangle. In
this way, nine conductors are suspended from each tower. Each group of
three conductors appears as one large line on the photography because
of the scale. The line is reported to be protected against direct light-
ning strokes by two steel ground crires running along the tops of the
towers for the entire length of each circuit.
Due to the small scale of the photography the insulation con-
figuration is not evident. However, collateral material reports that
the insulators are a porcelain suspended type consisting of 22 units per
suspension string. The total length of the suspension string assembly
is reported to be
