Abstract :
The steel tower applying large size angel steel which limb width exceeds 200mm is characterized with good integrity of material, clear force transmission, simple node structure, saving bolts and filling plate, convenient assembly and erection etc advantages. Technical and economic advantage of Q420 large size angle steel tower has been validated in ±800kv ultra-high DC Jinping-Sunan power transmission line engineering. It has been become a tendency to use Q420 large size angle steel to substitute angle steel tower with large design carrying capacity of common combined specification (limb width is 200mm and below). This paper makes thorough analysis and summary on application condition, application characteristic, technology and economy of application, design and research of application, application principle etc of Q420 large size angle steel.
