GENERAL NOTES for CONVERSION TABLE

(Old Bulletin 50-5 to New Bulletin 1728F-803)

  1. The old drawings of the primary deadend and suspension assemblies show two 10" (25 cm) suspension insulators; the new drawings show three, 4 1/4" (11 cm) suspension insulators. Any arrangement which uses materials from the "List of Materials" (Informational Publication 202-1) is acceptable. The material descriptions and quantities need to be changed accordingly. See the "General Construction Specifications" of Bulletin 1728F-803 for additional information.
  2. The old drawings of the primary and neutral deadend and suspension assemblies specify "deadend assemblies" and "angle assemblies" (items "ca" through "ce") on the drawings and in the material lists. Old guide drawings "M41-1" through "M42-21" show construction details and materials for these various assemblies. The above construction details and materials are shown in the "Tying Guides" of Section "L" of new Bulletin 1728F-803.
  3. The new pole top assemblies of Bulletin 1728F-803 utilize the hole spacing of the new pole framing guide in drawing "W1.1G."
  4. The drawings and specifications of new Bulletin 1728F-803 specify the use of a square, 3" (8 cm) curved washer for all primary and neutral deadend assemblies instead of the square, 2 1/4" (6 cm) flat washer specified in old Bulletin 50-5.
  5. The drawings and specifications of new Bulletin 1728F-803 specify the use of an anti-split bolt assembly on all pole top assemblies with double pole top pins and insulators.
  6. The drawings and specifications of new Bulletin 1728F-803 specify the use of a square, 2 1/4" (6 cm) flat washer beneath the shoulder of all 7.2 kV crossarm pins.
  7. Generally, the allowable transverse loading of pole-top assemblies in new Bulletin 1728F-803 is the same as those in old Bulletin 50-5. However, the maximum line angles for the new assemblies are more restrictive (smaller) than those of the old assemblies. USE THE TABLES FOR MAXIMUM LINE ANGLES IN NEW BULLETIN 1728F-803.
