The power supply system for urban rail transit consists of the entire power supply system that delivers electricity to the trains running on the urban rapid transit line through high-voltage transmission networks, step-down at main substations, distribution networks, and step-down and rectification (converted to direct current) at traction substations from the power system.
Core Equipment of the Rail Transit Power Supply System: Pearl Electrical is a professional manufacturer of rail transit power supply equipment. It can supply high-voltage transformers and main transformers for the high-voltage transmission networks and main substations of various rail transit power supply systems, provide distribution transformers for distribution networks, and provide traction transformers for traction substations.
Pearl Electric’s Rail Transit Supply Performance: Established for more than 60 years, Pearl Electrical has provided power transformers and distribution transformers for railways, subways, high-speed railways, and airports in various regions. Among them, the amorphous alloy dry-type transformer independently developed by Pearl Electrical is a high-performance and high-efficiency product. The following are some important achievements:
