Eco-Friendly Electric Furnace Transformer Solutions

Eco-Friendly Electric Furnace Transformer Solutions​

Eco-friendly electric furnace transformers have become key equipment driving the green transformation of the electric furnace smelting industry. This solution, through innovative design and strict material selection, establishes an environmentally friendly system covering the product's entire life cycle:

1. ​Core Eco-Material Applications:​​
• ​Halogen-Free Flame-Retardant Insulation Materials:​​ Fully adopts halogen-free materials such as ceramifiable silicone rubber and Nomex® aromatic polyamide paper. These do not release toxic halogen-containing fumes under high temperatures or short-circuit conditions, significantly enhancing electrical fire safety and protecting operators and the ecological environment.
• ​Low Environmental Impact Material Management:​​ Strictly adheres to standards such as RoHS, utilizing high-purity copper wire with sulfur content below 10 ppm, heavy-metal-free eco-friendly paints, and recyclable vegetable oil-based insulating oil (HVI), completely eliminating the use of toxic substances like lead, mercury, and hexavalent chromium.
2. ​High-Efficiency & Energy-Saving Design:​​
• ​Ultra-Low Losses:​​ Employs high-permeability materials like high permeability-oriented silicon steel (e.g., HiB steel) and amorphous alloy cores, combined with precise electromagnetic calculations and foil winding technology. No-load losses are reduced by over 35% compared to national standards, load losses decrease by 15%-20%, achieving a standard operating efficiency exceeding 97.5%.
• ​Intelligent Thermal Management:​​ Features optimized cooling structure design, equipped with an efficient oil circulation system and an intelligent air-cooling control module, enabling precise temperature rise control. Ensures coil hot-spot temperatures remain below 80°C at 95% load rate, reducing additional energy consumption.
3. ​Quiet Operation & Low Vibration Structure:​​
• ​Noise Suppression Technology:​​ Utilizes step-lap joint core construction, constrained lamination structures, combined with elastic shock absorbers and a composite sound insulation barrier for the tank (e.g., lining with sound-absorbing rock wool + external aluminum fiberboard), ensuring noise levels ≤55dB(A) at 1 meter.
• ​Vibration Control Solution:​​ Relies on 3D magnetic field simulation to optimize core and winding mechanical strength. Base installation incorporates high-damping rubber pads, effectively limiting equipment vibration velocity (RMS) to ≤2.0mm/s, significantly reducing structure-borne noise transmission.
4. ​Full Life Cycle Environmental Management:​​
• ​Clean Manufacturing Processes:​​ Implements Vacuum Pressure Impregnation (VPI) to replace traditional dipping processes, achieving an 85% reduction in Volatile Organic Compound (VOC) emissions; welding fume purification efficiency ≥99%.
• ​Protection & Recycling System:​​ Features an IP55-rated protective enclosure overall. Key internal components employ triple-layer Electromagnetic Compatibility (EMC) shielding to prevent oil leakage and stray magnetic field interference. Material disassembly labeling is defined at the design stage, enabling ≥95% recovery rates for materials like copper and iron.
