Rail Transit
Digital power supply and distribution solutions for rail transit power systems.
Industry Pain Points
-
High Load & Power DemandRail transit requires high load capacity and fast response from distribution equipment due to heavy power loads.
-
Uninterrupted Power Supply24-hours operation of subways, light rails, etc., demands highly reliable distribution equipment to avoid passenger delays or safety risks from outages.
-
Strict Environmental AdaptabilityDistribution equipment must withstand complex conditions, underground humidity, extreme temperature changes, vibrations, that affect performance.
-
Complex Lines & Maintenance DifficultiesThe large-scale system with equipment across stations and lines complicates maintenance, requiring rapid fault localization and handling.
Daqo Solutions
Rail transit digital power systems fully upgrade traditional electrical equipment and components in mechanics, operation, arcing suppression, earthquake resistance, and energy efficiency, ensuring higher-performance primary equipment meeting stricter standards.
Daqo's system uses domestic high-performance embedded platforms and IEC 61850 for advanced integrated power monitoring, with a "cloud-pipe-edge-device" architecture enabling intelligent O&M of power systems and supporting full-life-cycle equipment management.
