110kV Furnace Transformer for Steel and Alloy Smelting – High Power Factor Energy Saving Design

In modern smelting industries, reliable and high-performance power equipment is essential for producing high-quality steel and alloy materials. The 110kV furnace transformer is designed as core process equipment for electric furnace applications, integrating advanced manufacturing technology, optimized electromagnetic design, and robust mechanical structure. This transformer provides exceptional stability, high efficiency, and long service life, meeting the demanding requirements of industrial smelting environments.

Wide Range of Electric Furnace Applications

Electric furnace transformers are used in electric arc furnaces, submerged arc furnaces, refining furnaces, electroslag furnaces, and salt-melting furnaces. They support the smelting of corundum, silica sand, calcium carbide, sulfur, graphite, metallurgical auxiliary materials, cast steel, carbon ferromanganese, ferrovanadium, silicon-manganese alloys, and other industrial materials. The available voltage level reaches up to 110kV, rated capacity up to 80,000kVA, and single-unit weight up to 120 tons, suitable for both medium and large-scale smelting operations.

High Power Factor Energy Saving Technology

The energy-saving furnace transformer adopts an optimized electromagnetic design with a high power factor. The average operating power factor can reach 0.93 compared to approximately 0.8 for conventional transformers. This improvement reduces reactive power consumption and eliminates the need for additional compensation equipment. Each unit can save more than 10,000 kWh of electricity per day, significantly reducing operating costs in large-scale smelting facilities.

Core Technical Specifications

The rated primary voltage is available up to 110kV with additional options such as 35kV and 10kV to match industrial power grid requirements. Rated capacity reaches up to 80,000kVA to support various smelting scales. The core uses high-permeability silicon steel sheets with a five-step stepped lamination structure to reduce magnetic losses. Windings are made of high-quality oxygen-free copper conductors to improve conductivity and reduce temperature rise. The transformer supports 50Hz and 60Hz frequency systems and complies with IEC 60076, GB 1094, and IEEE C57 standards.

Low Loss and Quiet Operation

The high-permeability silicon steel core minimizes no-load loss and improves energy efficiency. The five-step stepped lamination reduces magnetic flux leakage and vibration, lowering no-load loss by 15% to 25% compared to conventional models. Optimized structural design also keeps operational noise levels low, meeting industrial environmental requirements.

High Conductivity and Long Service Life

The transformer windings use oxygen-free copper electromagnetic wire, offering superior conductivity and reduced resistance. This design lowers load loss and reduces heat generation. The improved corrosion resistance and mechanical strength ensure a service life exceeding 20 years even under harsh smelting conditions.

Strong Overload and Short-Circuit Capability

The reinforced winding structure and high-strength clamping system allow continuous operation under 120 percent overload conditions. Enhanced mechanical strength improves short-circuit withstand capability and prevents deformation during sudden fault conditions, ensuring continuous production and equipment safety.

Optimized for Smelting Efficiency

The transformer delivers stable voltage and current output for electric arc furnaces and refining furnaces. Accurate power control improves temperature stability, enhances metal purity, and increases smelting yield. This makes it ideal for high-quality steel production and alloy smelting applications.

Industrial Applications

The 110kV furnace transformer is widely used in electric arc furnace steelmaking, alloy steel production, ferroalloy smelting, metallurgical plants, foundries, and integrated steel mills. It provides stable high-power supply for continuous smelting operations and improves production efficiency.

Compliance and Quality Assurance

The transformer is designed and manufactured according to IEC 60076, IEEE C57, and GB 1094 standards. Strict quality control processes including vacuum oil filling, temperature rise testing, short-circuit simulation, and full routine testing ensure reliability and long-term performance in industrial smelting environments.

Customization and Technical Support

Flexible design allows customization of voltage level, capacity, impedance, cooling method, and installation configuration. Complete technical support including engineering consultation, installation guidance, and after-sales service ensures seamless integration into steel and alloy smelting projects.
