Many trains are equipped with a heat sink (power kicker) for cooling power transistors that control the electric voltage and frequency. With the N700 rolling stocks of the Tokaido Shinkansen lines, there are no electric fans. Instead, our ultra high-performance power kicker [PK-S] which holds the leading market share is being used. It is capable of cooling high-power transistors with the air flow generated during operation. The power kicker is also being used in high-speed trains in China and other countries.
Green Trough is a covered protective duct made of recycled resin, and is used for burying cables near the surface of land alongside railways. Its weight is only one-quarter that of concrete ducts, enabling ducts to be transported manually and reducing the construction period. In addition, ducts made of recycled plastics are eco-friendly and offer excellent strength, flame retarding properties, and workability.
A stackable cable duct system for installing multiple underground cables. EFLEX Square is available in 5 sizes ranging from 50mm to 150mm internal diameter. It’s square shape allows for fast, simple installation of underground cables, especially where space is limited. Each flame retardant duct is supplied in 5.3m lengths with built-in male and female connectors for rapid watertight installation. EFLEX Square ducts are flexible, eliminating the need for dedicated bend pieces, and when installed, EFLEX Square can withstand loads of 25t. An extensive range of innovative accessories allow for seamless integration with existing installations and pits/handholes.
Optic Ground Wire: The stainless steel tube is hermetically sealed by seamless welding without any pinholes or leak. The tube is filled with moisture/water resistant gel. Furukawa can make this cable up to customer’s specification.
