Concrete Conquers Desert Environment

摘要

Concrete poles support distribution and transmission overhead lines in Oman. Overhead lines face severe environmental problems in the desert of the Gulf state of Oman, especially in the vicinity of coastal areas. Oman has desert areas bordering the Arabian Gulf and the Indian Ocean. Its wood poles with porcelain and glass insulators suffer from such environmental problems as vast temperature changes, sand abrasion, salt pollution (mainly calcium) from the limestone desert rock, an extremely dry atmosphere, high temperatures, coastal fog, overnight humidity changes (dew formation) and diesel (sulfur) fumes where the overhead lines are located in close proximity to desert tracks.
