General Order 64-A

Appendix F

Typical Problems

Method of determining the construction requirements as provided in this order under the following assumed conditions:

Part 1.    Crossing Problem–A Class H and a Class C circuit Crossing over a major railroad, major Class C circuits and a highway.

Part 2.    Dead End Problem–H and Class L circuits at a dead end.

Part 3.    Angle Pole Problem–Guying a pole supporting Class H and Class L circuits at angles in lines.

The problems are computed on the assumptions of light loading conditions, with Grade “A” construction used for the power circuits and Grade “F” construction used for the communication circuits except in the crossing spans.  The actual construction involved in these Typical Problems are made to conform to current good practice and indicates where and in what manner the minimum requirements of the rules are exceeded or maintained.
