Waterproof sleeve for underground outer walls contributing to energy equipment protection, labor-saving, and flood prevention.
In the protection of energy facility equipment, stable protection from water disasters caused by water intrusion into pits is required. Particularly around important equipment in underground structures, even minor leaks can lead to serious accidents. In response to these challenges, "Pipe-in-Sleeve" provides pre-waterproof treatment at the factory and offers prefabricated products, reducing complicated on-site work while providing stable waterproof performance, contributing to the integrity of energy infrastructure. 【Usage Scenarios】 <Measures against water intrusion in the outer wall of important facility pits> - Water tree: Protection of underground buried cables - Protection of electrical systems and other equipment - Reduction of hygiene and environmental deterioration - Prevention of odor diffusion due to water stagnation, etc. 【Benefits of Implementation】 - Equipment protection through reduced risk of water intrusion - Labor savings: Shortened construction time and reduced worker burden - Improved reliability of infrastructure due to stable waterproof performance ●JECA Fair 2026/Product Competition: Received the Encouragement Award from the Japan Electrical Construction Association (under the name of Furukawa Electric Co., Ltd.)● *For more details, please feel free to request the catalog directly via email or download it from the "EPJ Corporation" "Iprosu Special Site" through the related links.
