NEW TRANSMISSION
LINE BETWEEN CALDWELL
AND ONTARIO

AND ONIAbip
urorL has been commenced on the
,,.aner,ission line between Cald"pii
and ontario, the survey OF whlcn "aS
made some months ago, and IL 20
boned to finish the construction %
tbl line SO that operation OF II may
hepin prior to the opening OF the II
Tfgation season. Construction cle%'

The line will. be type OF CON
gtruction new in this sectlon OF INC
country. but well known else"heIe'
csnecially in California and IN the
eastern States, known in the electrl.
ca1 world as the "H-frame type Oh
line. hut what to the average opser'-
er would be called a double-pole hne'
According to the engineering data
the line is designed for operation al
1872. 900 volts, which is twice the
voltage of the present main Trans
mission line into Ontario at the pre-
cent time The line will be set up
on poles varying in length, according
to the ground conditions, from ilfty
TO sixty-five feet, which will be set IN
parallel fourteen feet apart and whlch
will support a cross-arm twenty-nlne
feet long. From the cross arm Will
3 ri of
insulators, to each one of winch
conductor cable will be tied The
cable will be composed OF seven
strand, steel, reinforced aluminium
These conductors, which transmit the
electric energy, are fourteen ieel
apart, one from the other, distance
between outside wires being twenty
eight feet. The average span OF line
between stations, as the double-pole
structures are known, will be about
ESQ feet. although here and there
snans NAV be shortened or heightened
depending upon the topography OF the
land traYersed Each pole along the
line will be equipped with ground
wire. this wire being installed foI
protective purposes and to lessen
lightning hazards.
In the building Of such a line the
highest standards of engineering
practice were. adopted and used, and
in its course THE line was located
along the most direct route between
terminal points, the aim having been
to have as few angles or turns IN the
line as the ground conditions would
permit. No houses or buildings Of
hU
good and sufficient clearance being
maintained all along the way. Right
of-way fifty feet in width over the
private lands through the country
have been secured from the land
owners except in but a few instances,
and from the Federal Government
over the vacant lands. Only at one
point, a little south of Ontario, does
the line effect railroad property, and
there the crossing is at substantial,
right angle so that the least possible
effect is occasioned to the railroad
signal wires and other wire lines. tn,
whole endeaYor OF the engineers II
the laying out and construction of tbs
line was to keep away from proximity
to telegraph and telephone lines ana
by taking the shortest possible route
to encroach as little as possible upon
private lands.
The building Of the line was made
necessary by the demand for the
service in the Payette-Weiser section
and in the Ontario and Huntington
territories and will provide ample
capacity for the service and the in
creasing demand for long time to
come. With this additional artery of
supply, it will be possible to shut
down one line or another for repairs
or reconstruction reasons, which
practically provides dependable ser
vice to the territory in almost any
emergency. The Power Company
feels it a duty not only to keep
abreast of the countryside develop
ment but to keep sufficiently in ad-
vance of it so that any unexpected
demand for its service can be met.
