Features and Strengths
12-Pulse Rectification
Harmonic Suppression: Dual 30° phase-shifted outputs enable 12-pulse rectification, eliminating 5th/7th harmonics. Complies with IEEE 519/GB-T 14549 standards to avoid grid penalties.
Power Quality Boost: Reduces line losses and filter costs. Power factor >0.95.
Intensive Cooling System
ONAF Forced Cooling: High-flow oil pumps + turbo fans + expanded radiators limit temperature rise to ≤65K (vs. 75K per Chinese national standard).
High-Temp Insulation: Class H (180°C) materials withstand 150% short-term overload without derating.
Industrial-Grade Overload Capacity
Dynamic Load Handling: Supports 120% load for 30 mins and 150% for 10 mins (upgradeable). Handles cold-charge startup surges effortlessly.
Shock-Resistant Design: Reinforced windings endure furnace vibration.
Optimized for MF Furnaces
High Impedance (6-8%): Limits short-circuit current to protect power systems.
Low-Loss Core Steel: 15% lower no-load loss vs. national standards. Saves >$10k/year (for 2000kVA units).
Application
Metal Smelting: Ferrous/non-ferrous metals (steel, copper, aluminum, zinc)
Foundry Lines: Paired with induction furnaces, holding furnaces, pouring systems
Scrap Metal Recycling: Melt systems for metal recovery
Superalloys: Specialty steels, precision alloy production
