Transmission Steel Pole 220-500kv
A transmission steel pole (also called a tubular steel transmission pole ，monopole，Steel pipe pole or Overhead line steel pole)
Voltage: 110kV – 500kV (typical: 110kV, 220kV, 330kV,).
Purpose: Long-distance, high-voltage power transmission between substations.
Design: Taller (20m – 60m), heavier, stronger bending resistance for large spans and heavy ice/wind loads.
Footprint: Smaller than lattice towers, but larger than distribution poles.
Accessories: Fewer attachments (mainly insulators and conductors).
All poles are hot-dip galvanized according to ISO 1461, ASTM A123, or GB/T 13912, ensuring 40+ years of corrosion protection. We manufacture strictly to customer drawings or provide full design services based on your technical parameters (voltage, height, load, environment).
