We would like to share feedback received from a certain railway company that has been using multiple PDCE units over several years. This company has traditionally struggled with lightning damage, particularly in elevated sections in the city center. In 2013, a train was struck by lightning on a bridge, causing significant transportation disruptions. As a preventive measure, PDCE lightning rods were gradually installed not only on bridges but also in elevated sections. "We have not experienced any lightning damage in the areas where the rods have been installed since then, and we are feeling the effects of lightning suppression," is the feedback we have received. 【Case Summary】 ■ Issue: The company had been troubled by lightning damage, especially in elevated sections in the city center. ■ Effect: There has been no lightning damage in the areas where the rods have been installed to date. ■ Survey Area - Central Point: Seijo Gakuen Mae Station [Latitude 35°38’25"/Longitude 139°35’57"] - Survey Range: 10km x 10km centered on the above point. *For more details, please download the PDF or feel free to contact us.

We would like to share feedback received from a local broadcasting station in Toyama that has been using multiple PDCE units over several years. At this station, the main transmission site and relay stations are installed on mountain peaks, where the probability of direct lightning strikes is high. When a strike occurs, failures in the power supply and broadcasting equipment frequently happen, and if damage occurs, it can take several hours of hiking through snowy mountains to reach the site, which has been a source of concern. "We have received feedback that since we replaced four relay stations along the coast, which had a high incidence of damage, with PDCE lightning rods four years ago, we have not experienced any lightning damage," they reported. [Case Overview] ■ Challenge: The high probability of direct lightning strikes frequently caused failures in the power supply and broadcasting equipment, and if damage occurred, it could take several hours of hiking through snowy mountains to reach the site. ■ Effect: There has been no lightning damage for four years. ■ Survey Area - Survey Location: Toyama Prefecture [Latitude 36°49'27"/Longitude 137°12'42"] - Survey Range: 60km x 60km centered around the above location. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where a "dream home" was completely destroyed by lightning during a torrential downpour, and a new house was rebuilt over a year and a half, incorporating the "PDCE lightning rod." After the incident, the customer researched lightning protection measures on their own, but felt uncomfortable with the information found online, which mainly discussed methods of attracting lightning to the rod and grounding it. Continuing their research, they discovered our lightning suppression product and proceeded with the installation. They have shared, "It has been six years since the lightning strike, and we are living with peace of mind."

To the railway company, we would like to introduce a case study of lightning protection measures that were implemented after incurring hundreds of millions in damages, with no lightning strikes occurring over a span of ten years. In the summer of 2013, frequent power outages were occurring due to lightning strikes affecting the protective devices at substations. Shortly thereafter, a lightning strike occurred near a train traveling between Izumi-Tamagawa and Noborito, resulting in damage to some of the equipment necessary for operating the train. As a measure to prevent recurrence, the only solution was the PDCE, and 26 Junior-Marine units were installed at the damaged Tamagawa Bridge and elevated bridge sections. Subsequently, 32 units were installed between Seijo-Gakuenmae Station and Kitami, 58 units between Gotokuji Station and Kyodo Station, and 97 units between Kyodo Station, Chitose-Funabashi Station, and Soshigaya-Okurayama Station, focusing on the elevated bridge sections. [Case Overview (Excerpt)] - On August 12, 2013, a lightning strike occurred near a train traveling on the Tamagawa Bridge. - While searching for lightning protection measures to replace the overhead ground wire. - 26 Junior-Marine units were installed in the section between Izumi-Tamagawa Station and Noborito Station. - A lightning strike near Katase-Enoshima Station resulted in damages amounting to hundreds of millions. - Even railway companies that prioritize proven results are being recommended "new lightning rods." *For more details, please download the PDF or feel free to contact us.

August is a time when about 30% of lightning damage occurs, indicating a period of heightened weather risk.
