Three Core Technologies — One Clear Winner for Every Application
Silicon Steel Stacked Core
JUYULONG provides transformers, box-type substations, complete switchgear, EV charging piles, and charging station controller solutions for power distribution and EV charging projects.
Silicon Steel Tridimensional Toroidal Core
This material is chip-resistant, stain-resistant, and thermally stable, ensuring durability and practicality for daily and professional use.
Amorphous Alloy Tridimensional Toroidal Core
JUYULONG provides transformers, box-type substations, complete switchgear, EV charging piles, and charging station controller solutions for power distribution and EV charging projects.
Precision Manufacturing at Every Stage
Winding — Transformer coils are wound using dedicated precision equipment, with every unit tracked via our MES (Manufacturing Execution System) for real-time quality control and traceability.
Assembly — Our assembly area can simultaneously handle 300+ units across multiple capacity specifications. Digital management processes and intelligent logistics ensure consistent quality at scale.
Testing — Every transformer undergoes rigorous electrical testing including impedance, no-load loss, load loss, insulation resistance and applied voltage tests before shipment.
Sheet Metal & Enclosures — Automated laser cutting and robotic bending equipment ensure dimensional precision for transformer tanks and switchgear enclosures. Robot-welded oil tanks deliver consistent seam quality and long-term leak resistance.
Smart Charging — Beyond Hardware
Our integrated Fast Charging Digital Operation Platform (FCDOP) connects your entire charging network into a single management dashboard. Capabilities include: – Real-time device monitoring & fault alerts – User management & RFID / APP authentication – Revenue reporting and financial reconciliation – Order management and analytics – Remote OTA firmware updates – Multi-site management for fleet operators and charging network operators
