Engineered to meet the stringent European Ecodesign directives and local Spanish UNE standards.
Spain is experiencing a rapid energy transition under its ambitious National Energy and Climate Plan (NECP / PNIEC). With targets aimed at sourcing over 81% of electricity from renewable generation by 2030, the Spanish electrical transmission and distribution networks are undergoing major modernization. Under the oversight of Red Eléctrica de España (REE), grid operators are demanding transformers that deliver exceptional reliability, smart thermal management, and minimal no-load losses.
In industrial sectors spanning Basque Country, Catalonia, and Andalusia, heavy manufacturing, green steel production, and automotive assembly facilities require highly specialized transformer equipment. High-voltage distribution substations must support unstable load variations stemming from vast solar farms in Murcia and offshore wind configurations along the Galician coast. This demands next-generation technical configurations—such as 3D triangular rolled cores and environmentally benign dry-type units—to prevent catastrophic grid faults.
Globally, the electrical infrastructure sector is shifting away from traditional planar silicon steel structures toward amorphous alloy cores. The core benefit of amorphous metal lies in its random molecular orientation, which dramatically reduces magnetic hysteresis and eddy currents. This leads to a remarkable 70% to 80% reduction in no-load losses compared to traditional cold-rolled grain-oriented (CRGO) steel transformers.
Furthermore, the introduction of 3D triangular wound cores has redefined three-phase equilibrium. Unlike the traditional 2D flat stacked designs, the 3D configuration aligns the magnetic circuit symmetrically, eliminating third harmonic distortions and ensuring natural cooling balanced across all phases. This technical design is critical for localized Spanish applications where high-temperature Mediterranean summers impose heavy thermodynamic stress on cooling oil formulations.
Deeply developing the machinery and transformer fabrication industry, empowering the global grid transition.
On the shores of the picturesque Taihu Lake lies Wuxi, known as the "Land of Fish and Rice." This highly industrial region has nurtured Wuxi Shuhong Machinery Technology Co., Ltd. Since its establishment in 2018, Shuhong Machinery has consistently prioritized technological innovation and premium service, advancing rapidly in electrical machinery manufacturing to become a trusted global partner.
Our founder's passion is rooted in practical machinery manufacturing. Having spent over a decade in the industry—transitioning from front-line technical engineering roles to global management—our leadership witnessed domestic machinery shift from "following" traditional methodologies to "leading" green smart grid designs. This unique perspective guided our investment in highly specialized manufacturing systems that serve energy-efficient transformer production worldwide, including the demanding Spanish market.
During an exchange program for state grid projects, our engineering team observed that traditional transformers suffered from structural flaws in temperature control, thermal degradation, and restricted lifespans. In response, Shuhong Machinery concentrated efforts on R&D for advanced winding equipment and core cutting machines.
By overcoming key thermal and mechanical challenges in our R&D laboratories, we developed equipment capable of producing transformers that demonstrate a 30% reduction in temperature rise and a stable 15-year operational lifespan, earning critical acclaim across European and Asian industrial networks.

Tailored system integration to meet specific utility, commercial, and heavy-duty industrial needs.
Spain’s high solar irradiation levels in southern regions necessitate specialized inverter-transformer configurations. We provide step-up transformers that efficiently handle transient harmonics and DC bias currents, preserving system balance under variable solar input.
Densely populated commercial centers require high safety standards. Our leak-free, self-extinguishing dry-type transformers eliminate fire hazards and avoid soil contamination risks, making them suitable for metro lines, hospitals, and high-rise structures.
Automotive and metal fabrication facilities in Zaragoza and Valencia generate significant grid feedback. Our customized planar wound core units maintain voltage stability, mitigate thermal stress, and lower power distribution losses.
Providing complete production machinery and transformer assemblies to support global manufacturers and Spanish engineering projects.
As global energy consumption rises, next-generation transformers must function as more than simple voltage-conversion equipment; they must become intelligent nodes in digital grids. The adoption of IoT-enabled thermal monitoring, real-time gas analysis, and automated tap changers is essential for predictive maintenance. This shift helps grid operators prevent outages, protect sensitive equipment, and lower operating costs.
In Spain, where the Ministry for the Ecological Transition and the Demographic Challenge enforces strict efficiency guidelines, these advancements are crucial. By deploying amorphous alloy cores and 3D triangular configurations, local facilities can achieve significant carbon emission reductions, helping meet EU neutrality targets.
"Since partnering with Shuhong Machinery, our substation's operational efficiency has improved substantially. The 3D triangular rolled core design has reduced no-load losses and helped stabilize voltage levels across our regional grid."
