Structural Features
Compact Structure for Narrow Transmission Corridors
Tubular pole geometry reduces occupied space and supports installation in urban and restricted right-of-way conditions.
Designed for Conductor and Environmental Loads
Structural calculations can be configured according to conductor loading, wind conditions, ice loading, and span requirements.
Corrosion Protection for Outdoor Service
Steel sections are hot-dip galvanized according to ISO 1461 or ASTM A123.
Modular Installation Design
Slip-joint or flange-connected segments support transportation efficiency and field assembly.
