Detailed Description
MEGATRO provide many types of 69KV steel tube angle Towers for our clients, which is widely used for oversea clients. 69KV steel tube angle Towers is used for urban power grid, it is one good choice for city power transmission due to its less space, less time to install and are aesthetical in appearance, compared to conventional lattice tower. In 69KV power transmission line, it must change direction, then steel tube angle Towers are used. Structures are classified as angle suspension, angle strain, and angle dead-end. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 69KV steel tube angle Towers project, we have skilled worker with certificated welders, and offers a variety of monopole types to meet client specific. Tapered steel and flanged steel poles feature designs that blend well into the environment and require minimum space for installation. Flanged steel poles are easy to handle and install. Slip type with precision fitted connections allow quick assembly of sections and total poles seems uniform and harmony with environment, especially accept by our foreign clients. Pole sections are available with identical base flange plates, allowing for simplified modifications of mounting heights. In material we often adopt mild steel (ASTM A36, Q235B), high strength and lower alloy (ASTM A572 GR50, GR65, Q345B, Q345C, Q420, Q460, S355J0, S355JR and equivalent materials). MEGATRO can optimize design and adjust monopole size to make it less weight, solid strength and economic cost. For tower surface, we adopt hot-dipped galvanization, or zinc coating on towers and components to meet ASTM-A123 standards or client accept standard...
