HOME site map privacy policy Yagyu Denki Kogyo Co., Ltd. has been manufacturing and selling rail bonds since its establishment in 1918. During that time, it has been working on improving product quality, developing new products, safe operation of trains, prevention of electrolytic corrosion of underground buried objects, etc. I have contributed, albeit a little. Most of Japan's electric railways, except for some such as the Shinkansen, use the DC distribution system, and most of them now use single-line overhead line type or third rail type electricity that uses rails as the return line of electric current. It is a railroad system. In this case, the rail connection is not electrically sufficient with the seam plate alone, and the rail bond is used as an electrical auxiliary conductor. In addition, many electric railways also use rails as AC signal circuits, so rail bonds are also regarded as important for signaling. The above is also a problem of the electric railway itself, but in recent years, while the electric railway has developed significantly, the underground metal body has also developed remarkably, and there is concern about the electrolytic corrosion accident of the underground metal body due to the return leakage current. It has been done. For the above reasons, the role played by rail bonds is of considerable importance. We would like to introduce our products here for your reference and look forward to your order.
