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.
