Transmission towers are critical structures in electrical power systems, designed to support overhead conductors at safe heights and ensure reliable electricity transmission over long distances. These towers are categorized based on their mechanical function (suspension towers for straight-line spans and strain/dead-end towers for directional changes or terminations) and circuit configuration (single-circuit or double-circuit). Common structural types include lattice steel towers, tubular steel poles, and composite designs, selected based on voltage levels (e.g., 230kV, 500kV) and environmental loads (wind, ice).
(a) Upper-Circuit Tower
(b) Wine-Cup Tower
(c) Chinese Cat-Head Tower
(d) Bridge-Type Strain Tower
(e) Dry-Type Strain Tower
(f) Delta-Type Suspension Tower

(i) 500kV Cross-Circuit Portal Tower
(j) 500kV V-Type Tower
Key Notes:
"Strain Tower" = "Dead-End Tower" – Used where conductors terminate or change direction.
"Suspension Tower" – Supports conductors without significant tension.
"Double-Circuit" – Carries two separate three-phase circuits.
"Portal Tower" – Common in high-voltage lines with wide spans.
"V-Type"– Often used for compact line designs.
