Strength standards for power transmission towers Kyushu Shikoku To raise in Chiba Prefecture, etc. November 29 5:07
In order to raise the standard in Kyushu, Shikoku, and Chiba Prefecture, where there was significant damage from Typhoon No. 15, the strength standards for power transmission towers that were set uniformly throughout the country were revised. I found that it was being considered.
In Typhoon No. 15 in September, two large steel towers for power transmission fell in Kimitsu City, Chiba Prefecture, and large-scale power outages continued mainly in Chiba Prefecture due to the damage of a large number of power poles. .
The standard for the strength of steel towers for power transmission is set to be able to withstand winds of 40 meters across the country, but in Chiba Prefecture, the maximum instantaneous wind speed seems to have reached 70 meters.
For this reason, the Ministry of Economy, Trade and Industry has revised its current standards and has established a policy to set strength standards according to the actual conditions of the region.
We are going to proceed with examinations based on the setting of standards for each municipality. In addition to Kyushu and Shikoku, where many typhoons are approaching, the standards are expected to be raised from now on in Chiba Prefecture, which suffered great damage.
The Ministry of Economy, Trade and Industry wants to urgently review the standards by presenting this policy to a working group that creates external experts.
