1975 outside Japan to promote large-scale project

After the first oil crisis, a number of countries, including Japan, the economic downturn, in this context, there are a number of large projects are entered to the near east.The company is also committed to in the near east, the development of the market for the first time in 1975 TAVANIR from Iran, power generation and transmission company to undertake large-scale transmission line project TS - 19 projects, and in 1977 to undertake the TS - 28 projects.At the same time, the company also outside Japan countries and regions to undertake the other large engineering, integrating power lines and underground cable engineering department for power engineering department, and conduct business, to strengthen the enterprise system.
As the first in Iran to undertake projects, the purpose of the TS - 19 from south of the Persian gulf coast to sal is located in the central region cut assorted (Sarcheshmeh copper mine power supply.The southern areas are most of the desert, and the central region to an altitude of 3000 meters high, so this is a difficult projects in multiple extreme conditions to promote.And TS - 28 projects to from the inside of the Caspian sea coast in the northern territory (Neka) power stations to the long-term lack of electrical power in Tehran, the capital of about 300 km of transmission line should be set up to connect two places.The littoral area of soft stratum area about 40 kilometers long, then jumped from tens of meters above sea level rise to 2600 m in the steep areas, where the warden, about 30 km and geological age of moist, therefore extremely hard project.
These projects engineering conditions are harsh, in the desert of southern extreme heat, the temperature can be as high as more than 50 ℃, and in the central region of the winter cold, the temperature can drop to close to 30 ℃ below zero, and all kinds of accident risk together, but even so, the company or from these projects accumulated a lot of proprietary technology, and effective use in the subsequent project.TS - 19 project was completed in March 1978, by the Iranian revolution and the iran-iraq war (Iran, Iraq), the effect of TS - 28 a programme, was completed in February 1982.
