No fissure, scar, overlap, layer or other defects Q235B/A36, Minimum Yield Strength ≥ 235 N/mm²Īs well as Hot rolled coil from ASTM A572 GR65, GR50, SS400, or any other standard by client required.ĬO2 welding or submerged arc auto methods Normally Q345B/A572, Minimum Yield Strength ≥ 345 N/mm² Steel tubular tower, Communication tower, Lighting rod tower, Radio and television tower, Electrified railway structure, Substation architecture Telecommunication tower KEHANG Transmission line steel pole tower, Angular tower Counterweights may be permitted on suspension towers. In case of conductor uplift, the cross-arm of tension towers shall be designed accordingly and proven by calculations. Wind loads on tower for “Quartering wind”. The design of the dead end tower shall consider conductor and earth wire tension without any offset for slack-span connections.The maximum out of balance longitudinal component of loading, taken as 15% of the actual maximum line conductor and earth-wire tensions.Resultant forces produced by the maximum tension of conductors or earth wire in the direction perpendicular to cross-arms.Maximum angle pulls, corresponding to type of towers. Under the angle of 45° (“Quartering wind” according to IEC 60826).Wind loads produced by solar aircraft warning light (if specified for supply).Wind loads produced by insulator strings.Wind loads produced by the effective portion of the adjacent conductor and earth wire spans including wind loads of aircraft warning spheres (if specified for supply).The transverse horizontal component of the maximum line and earth conductor tensions.Weight of solar aircraft warning light system (if specified for supply).
