Hangzhou Metro Line 5 is the first subway line to reach the north of Hangzhou city. After its opening, it connects seven urban areas including Yuhang, West Lake, Gongshu, Xiacheng, Shangcheng, Binjiang, and Xiaoshan. There are numerous natural landscapes and cultural stories surrounding Line 5, showcasing the exquisite cultural landscape of Hangzhou and reflecting its historical and cultural image as a famous city.
The total length of Hangzhou Metro Line 5 is about 56.21 km, and it is laid entirely underground. There are 39 underground stations, including 16 transfer stations. Known as the "King of Hangzhou Subway Transfer", during the construction process, Sfier Electric's subway electrical fire monitoring system, subway fire protection equipment power monitoring system, and various power instruments were adopted.
SCK680-B Electrical Fire Monitoring Equipment

SCK600Y residual current electrical fire monitoring detector (fire protection secondary bus)
SCK600YT
The SCK600YT temperature measuring electrical fire monitoring detector is connected to the electrical fire monitoring equipment or monitoring unit through the fire protection secondary bus, achieving timely reporting of alarms and faults; Combined with NTC temperature sensor, it can measure 4 temperature signals in real time, with a temperature measurement range of -10~150 ° C. LED lights can indicate the detector's operating status in real time. TH-35-7.5 standard guide rail installation, external dimensions: 36X90X63.5, unit: mm.
The electrical fire monitoring system inside the subway station monitors the residual current and temperature of the electrical circuit in real time. When the measured value exceeds the alarm threshold, it triggers an audible and visual alarm action, effectively ensuring personal and property safety. The fire equipment power monitoring system monitors the voltage and current of the incoming and outgoing lines of the dual power supply circuit. In case of undervoltage, overvoltage, loss of voltage or overcurrent, it triggers an audible and visual alarm action to ensure the normal power supply of the fire equipment.
As one of the focuses of Jiangsu Sifei Electric's business, the subway electrical fire monitoring system for rail transit has become specialized and mature. Our company is committed to providing customized system solutions for customers.
