Change List for this Rule


General Order 95


Section II


Definitions of Terms as Used in The Rules of This Order


20.9     Conductor means a material suitable for: (1) carrying electric current, usually in the form of a wire, cable or bus bar, or (2) transmitting light in the case of fiber optics.


Note:     Revised November 21, 1990 by Resolution SU–6.


A.     Bundle Conductor means a group of conductors of the same phase and polarity.


B.       Lateral Conductor means a conductor extending in a general horizontal direction and usually at an angle of approximately 90 degrees to the direction of the line conductors.


C.       Line Conductor means an overhead conductor which extends from the last point of support on one overhead line structure to the first point of support on another overhead line structure.


D.     Open Wire Conductors mean communication conductors separately supported.


E.     Unprotected Conductors mean supply conductors, including but not limited to lead wires, not enclosed in a grounded metal pole or not covered by: a “suitable protective covering” (see Rule 22.8 ), grounded metal conduit, or grounded metal sheath or shield. Provisions for the use of such types of coverings are specified in certain of these rules.


Note:     Revised January 19, 1994 by Resolution SU–25.


F.     Vertical Conductor means a conductor extending in a general vertical direction between conductor levels on an overhead line structure.


G.     Insulated Conductors or Cables, suitable, mean supply conductors which are surrounded by an insulating material (see Rule 21.6), the dielectric strength of which is sufficient to withstand the maximum difference of potential at normal operating voltages of the circuit without breakdown or puncture. A weather-resistant covering of a supply conductor does not meet the requirements of this rule as to suitable insulation.


Note:     Revised November 6, 1992 by Resolution SU–15, January 19, 1994 by Resolution SU–25 and January 13, 2006 by Decision No. 05-01-030.


H.       Trolley Contact Conductor is the contact conductor itself and any energized support wire or messenger when used in catenary construction.  (See Rule 20.6-E.)


Note:     Revised January 13, 2006 by Decision No. 05-01-030.
