Power transmission and distribution pole
Electricity distribution is the final stage in the delivery of electricity to end users. A distribution system's network carries electricity from the transmission system and delivers it to consumers. Typically, the network would include medium-voltage (1kV to 72.5kV) power lines, substations and pole-mounted transformer, low-voltage (less than 1 kV) distribution wiring and sometimes meters.
In generally, distribution pole often use power voltage less 230KV, MEGATRO had provided too many distribution pole to overseas client, I.E for African client we often design 132KV or below voltage power transmission project; for Asian client, we provide 110KV or below distribution line pole.
MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of Power transmission and distribution pole, we have skilled worker with certificated welders, and offers a variety of Power transmission and distribution pole 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 steel utility pole 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...
