Additionally, it is lightweight and easy to handle, facilitating easy processing and reducing labor during installation. The increased inner diameter (nominal diameter +10mm) contributes to size reduction during tube selection, leading to cost savings, and it also helps shorten construction periods and reduce construction costs. This product has been meticulously developed by cable manufacturers. Please make use of it to promote the widespread adoption of renewable energy. 【Features】 ■ High bending rigidity and straightening recovery force suppress local bending. ■ Low static friction coefficient reduces cable threading tension. ■ Approximately one-third the weight compared to typical PVC power cable protection tubes. The 4m straight tube is easy to handle and lightweight. ■ Bending construction is possible without the need for bending tubes (typical tubes require dedicated bending tubes). *For more details, please refer to the PDF document or feel free to contact us.

Delivery Title: Development of a "Slim Trench" with Indicator Function Furukawa Electric Co., Ltd. has developed a surface-mounted cable trench (indicator trench and flat trench) with an indicator function that can be installed on road surfaces. ■Background■ In Japan today, discussions are underway for smart cities aimed at optimizing infrastructure and facilities to enhance convenience and comfort. In smart cities, various electronic devices are installed throughout the urban area, while communication and power cables, as well as water and gas lines, are buried beneath the pavement. One of the challenges in smart cities is to install new equipment while avoiding these existing utilities and ensuring cable routes. ■Product Features■ This product has a thickness of 55.5mm, which is about half the thickness compared to the minimum size class of 130mm for concrete cable trenches, allowing for a reduction in the amount of ground excavation required. This thickness is comparable to paving materials such as interlocking blocks and tactile paving blocks, enabling replacement with existing paving materials without significant changes to the foundation. Additionally, by integrating the indicator and cable conduit, simple installation is made possible.
