Guangzhou Metro Line 1

       The operation of the subway system mainly depends on the low-carbon power supply system. The construction of the power supply system is a very important part. The safety and stability of the railway power supply system along the road is highly related to the power supply equipment. The low-carbon system requires high-load operation during the day and light load at night, and the power load fluctuates greatly and energy consumption is very high.

       Guangzhou Metro has always attached great importance to energy conservation and emission reduction, and successively adopted HAIHONG's 3300kVA capacity open ventilated amorphous alloy 3D wound core dry-type transformer and 1250kVA capacity open ventilated amorphous alloy 3D wound core dry-type transformer. The open ventilated amorphous alloy 3D wound core dry-type transformer combines the amorphous alloy material with the 3D wound core technology. The amorphous alloy material not only has the excellent performance of silicon steel in flame retardancy and moisture resistance, but also has excellent magnetic conductivity. The process of electromagnetism and magnetoelectricity is very easy to complete, and the loss is greatly reduced. The product also inherits the advanced energy-saving advantages of the 3D wound core technology. It is a transformer with a leading energy efficiency level at present, and the product has the characteristics of safety, reliability, environmental protection, and low operating noise. HAIHONG assists Guangzhou Metro to create a new benchmark for green and low-carbon lines in the rail transit industry.
