Product Description

Key Highlights

  • Inverter & Harmonic Resilient: Engineered with reinforced insulation and electrostatic shielding to withstand high-frequency harmonics and voltage fluctuations from string/central PV inverters.
  • Low Loss & Eco-Design: Built with high-permeability cold-rolled silicon steel and 100% oxygen-free copper, minimizing LCOE for utility-scale solar farms.
  • Hermetically Sealed & Maintenance-Free: Corrugated tank prevents oil contact with ambient air, extending insulation life for 20+ years in harsh desert and coastal environments.

Target Applications

  • Utility-scale & ground-mounted solar PV plants
  • Commercial & Industrial (C&I) rooftop solar grid-tie
  • Battery Energy Storage Systems (BESS) step-up integration

Custom Engineering & Capabilities

  • Configuration: Dual split-winding / multi-split inputs for multi-inverter paralleling.
  • Ratings: Primary 0.4kV–0.8kV up to 11kV/33kV/35kV (50Hz/60Hz).
  • Monitoring: Optional fiber-optic temperature sensors, Buchholz relay, and RS485/Modbus SCADA telemetry.

Standards & Quality Assurance

  • 100% compliant with IEC 60076 & ISO 9001.
  • Fully routine-tested (lightning impulse, partial discharge, temperature rise) before dispatch.
  • 20+ years of export experience with seaworthy packaging.
