General Order 95
Section II
Definitions of Terms as Used in The Rules of This Order
22.1 Lines mean those conductors together with their
supporting poles or structures and appurtenances which are located outside
of buildings.
A.
Conflicting Lines (lines in conflict or conflicts) mean lines so
situated with respect to each other (except at crossings) that the overturning
of one line will result in contact of its poles or conductors with the poles
or conductors of the second line, assuming no conductors are broken in either
line
except that lines on opposite sides of a thoroughfare are not considered
as conflicting if separated by a distance not less than 60 percent of the
height of the higher pole line above the ground line and in no case less than
20 feet (see Appendix
G, Figure 1
).
B.
Colinear Lines mean conflicting lines so situated that one line is
wholly or partly over the other line, often called “overbuild”.
Conflicting lines not “overbuilds” but separated a horizontal
distance of less than the required pin spacing of the highest voltage circuit
involved
Conflicting lines not “overbuilds” but separated a horizontal
distance of less than one foot, regardless of pin spacing (see Appendix G,
Figs 2
and 3
).
Note: For the purpose of measurement, the horizontal
distance between the conflicting lines shall be that distance measured horizontally
between vertical planes passing through the adjacent extremities of the
conflicting lines.
C. Tower Lines (Class E, H, L and T) mean supply lines, with supporting
metal structures having an outside dimension of more than 4 feet measured
either along or across the line in a horizontal plane at the ground level.
Metal supporting structures, such as “A” frames or “H” structures, having
a dimension from outside of one support to outside of another support greater
than 4 feet at the ground level will be classified as towers.
Guyed V–type or Y–type metal structures will be classified
as towers.
Note: Metal structures having maximum outside dimensions of 4 feet or less, measured along and across the line of a horizontal plane at the ground level, will be classified as poles under supply lines.
Note: Revised March 30, 1968 by Decision No. 73813.
D. Overhead Line Structures are the poles, towers, or structures located
outside of buildings and which support circuits and their related conductors
and equipment.
