The 3D wound core transformer technology promotes the steel industry to enter a new era of green and efficient power distribution

Under the driving force of the "Dual Carbon" goals, the steel industry, as a major energy consumer and carbon emitter, is accelerating its green transformation. Haihong Electric, with its independently developed Open Ventilated 3D Wound Core Dry-type Transformer and 3D Wound Core Oil-Immersed Transformer for the steel sector, provides high-reliability, low-energy consumption power distribution solutions, aiding the industry in stepping into a new era of green energy efficiency.

Current Power Demand in the Steel Industry

Steel enterprises often face challenges such as high energy consumption, concentrated and dense loads, and stringent requirements for power supply reliability. Traditional power equipment under high-load conditions frequently encounters issues like significant load fluctuations and high self-consumption, severely impacting production efficiency and causing energy waste.

Addressing Power Pain Points in the Steel Industry

Energy Saving and Emission Reduction to Support Carbon Reduction
Haihong's products adopt a 3D wound core structure, reducing load loss, no-load loss, and no-load current. For example, replacing a laminated core transformer (ZBSFB11-6000/10) with a  3D Wound Core Transformer (ZBSFB22-RL-6000/10) can achieve the following annual energy-saving effects:

·         Saves approximately 175,900 kW·h of electricity;

·         Reduces standard coal consumption by about 53.6 tons;

·         Cuts electricity costs by around RMB 128,400.

Outstanding Overload Capacity
The Open Ventilated 3D Wound Core Dry-type Transformer for the steel industry features high insulation performance and natural cooling efficiency, enabling low-temperature rise operation under long-term full-load conditions. The product perfectly matches the needs of the steel sector, avoiding power failures caused by insufficient transformer overload capacity.

Exceptional Short-Circuit Withstanding Ability
Compared to traditional laminated core transformers, the 3D wound core ensures balanced three-phase magnetic circuits, uniform and stable core force distribution, and strong short-circuit withstanding ability. This makes it fully compatible with the steel industry's frequent start-stop operations and high-impact load environments.

High-Reliability Design
The 3D Wound Core Oil-Immersed Transformer for the steel industry is suitable for highly corrosive environments such as pickling and cold-rolling workshops, preventing tank corrosion and oil leakage. The Open Ventilated 3D Wound Core Dry-type Transformer offers moisture-proof, pollution-resistant, and weather-resistant properties, along with crack-resistant coils, effectively defending against dust pollution and damp erosion.

Successfully Applied by Global Leading Steel Enterprises

The products have been deployed in numerous top steel companies, including WISCO Group, Baosteel Zhanjiang, Shougang Group, Ningbo Baoxin Stainless Steel, Ouyeel Industrial Supplies, JFE Steel Corporation, and Indonesia DCP Steel Company. They have cumulatively participated in nearly 100 steel industry power distribution system projects worldwide.

Haihong Electric will continue to deepen the application of 3D wound core technology in the steel sector, providing steel enterprises with more efficient, reliable, and environmentally friendly power equipment. We are committed to supporting the achievement of the "Dual Carbon" goals and offering safer, more reliable, and greener Chinese solutions for the global steel industry!
