Product Introduction

Engineered exclusively for modern medium-frequency induction melting furnaces, this transformer integrates 12-pulse rectification technology, advanced cooling systems, and high overload capacity. It solves three critical challenges in metal smelting—high energy consumption, harmonic pollution, and load surges—delivering efficient, stable, and eco-friendly melting operations.

Конструктивные особенности

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
Low-Loss Core Steel: 15% lower no-load loss vs. national standards. Saves >$10k/year (for 2000kVA units).
