"Transformer Seismic Resistance: Even if the emergency power supply is safe, the transformer is important." TTR

Seismic measures start with "transformers"! We achieve efficient disaster reduction measures (damage mitigation and early recovery).

The seismic isolation device "TTR type" significantly reduces the displacement of transformer terminal sections caused by large seismic motions, preventing power outages due to damage at the terminal sections and elsewhere. With the installation of TTR, a displacement of ±50mm or less at the terminal sections was achieved for all experimental seismic waves. Based on the building's response characteristics, it is possible to calculate and simulate the displacement of the transformer during an earthquake. In past earthquakes (such as those in Eastern Japan and Kumamoto), the heaviest transformers in the cubicles were damaged, leading to many cases where electricity could not be extracted even if emergency generators were intact. Transformers are not readily available, meaning that operations would be halted during that time. TTR not only protects the transformer but also enhances the rigidity of the entire cubicle, contributing to the protection of various relays and LCBs. It achieves efficient disaster mitigation measures (damage reduction and early recovery). 【Features】 ■ Significantly suppresses displacement caused by seismic motion with a special absorber at the top of the transformer ■ Effective even against continuous earthquakes ■ Can be installed within the cubicle ■ Minimal changes to panel size with TTR installation ■ Does not compromise the effectiveness of the installed vibration isolation device *For more details, please refer to the PDF document or feel free to contact us.
