220kV-500kV Double Circuit Lattice Transmission Tower
Extra High Voltage Infrastructure | IEC 60826 Compliant | 50-Year Design Life
Engineered for Grid Reliability
Our 220kV-500kV double circuit lattice transmission towers are engineered to meet the rigorous demands of China Southern Power Grid standards while optimized for Southeast Asian operational environments. With 23 years of manufacturing excellence, Xytower delivers infrastructure solutions that withstand tropical humidity, typhoon wind loads up to 45m/s, and seismic conditions prevalent across Malaysia, Myanmar, and Thailand.
Each tower undergoes rigorous quality control including hot-dip galvanizing exceeding 86μm coating thickness, ensuring corrosion resistance in coastal and high-humidity environments. Our optimized lattice geometry reduces steel weight by 8-12% compared to conventional designs without compromising structural integrity.
