Fire-resistant hexagonal mesh making a big impact in Japan's hydropower sector
2025-06-25
Turbines in Japanese hydropower stations are subject to long-term erosion from high-speed water flow and abrasion from silt, resulting in high equipment maintenance costs. Fire-resistant hexagonal mesh is woven from wear-resistant alloy wire and undergoes surface hardening treatment, effectively resisting water erosion and reducing blade wear. Its sturdy structure absorbs vibration energy generated during equipment operation, reducing the risk of failure. At hydropower stations around Lake Biwa, fire-resistant hexagonal mesh has been applied to turbine protection, significantly improving equipment operational stability. It holds promising prospects for future maintenance of hydropower equipment in Japan.
