Description

AC power lines can be categorized into transmission and distribution systems, with distinct characteristics based on voltage levels:

Transmission Lines

  • Extra High Voltage (345 kV): Uses large lattice towers reaching 120 feet high
  • High Voltage (138 kV): Employs either wood/steel poles (70-85 feet) or H-frame structures (65-80 feet)
  • Sub-transmission (69 kV): Uses wooden pole structures around 58 feet tall

Distribution Lines

  • Medium/Low Voltage (12-34.5 kV): Utilizes simpler wooden pole structures 37-40 feet in height
  • Typically found in residential and commercial areas
  • Shorter poles with simpler cross-arm configurations

Physical Characteristics

  • Height decreases as voltage level drops
  • Structure complexity reduces from transmission to distribution
  • Spacing between structures varies:
    • 300-foot spacing for 138 kV single-circuit
    • 600-foot spacing for H-frame structures
    • Closer spacing for distribution lines

The system progressively steps down voltage levels from transmission to distribution, with corresponding changes in tower height and design complexity.
