XIAOWEI pushes custom transformer design for harsh industrial projects

Jiangsu Xiaowei Electric Co., Ltd. is highlighting OEM/ODM transformer services for projects facing non-standard voltages, harmonic distortion, high-altitude cooling demands and corrosive environments. The pitch targets utilities, renewable energy developers and industrial operators that need application-specific electrical equipment instead of off-the-shelf units.

Why it matters: - Non-standard grid connections, mining sites and renewable energy installations often need transformers built for specific voltage, cooling and enclosure requirements. - XIAOWEI is positioning custom transformer design as a way to reduce voltage mismatch, overheating, corrosion and harmonic-related failures in harsh environments. - The offering is aimed at utility, industrial and energy customers that need project-specific equipment rather than standard catalog products.

What happened: - Jiangsu Xiaowei Electric Co., Ltd. said it offers OEM/ODM transformer design services for custom voltage ratio engineering, thermal management, environmental protection and harmonic mitigation. - The company released details of its custom transformer capabilities from Nantong, Jiangsu, China, on September 3, 2026. - XIAOWEI said it supports custom transformer projects for utility grids, industrial plants, renewable energy systems and other specialized installations.

The details: - XIAOWEI said its voltage customization covers primary operating voltages up to 35kV, including 34.5kV, 22.9kV, 19.92kV, 13.8kV, 12.47kV and 10kV inputs. - The company also said it can support larger substation transformer ratings up to 110kV and 230kV on demand. - XIAOWEI said it customizes vector groups such as Dyn11, Dyn1, Ynyn0 and Ynd11 to match grounding and distribution needs. - The company said multi-winding transformers can be built with dual secondary windings and 30-degree phase displacement for solar inverters, wind turbine step-up units and industrial rectifier plants. - XIAOWEI said its thermal designs use thermodynamic finite-element modeling to address high-altitude and high-temperature operation. - For liquid-immersed transformers, the company said it can increase radiator surface area, add corrugated cooling fins or integrate custom radiator configurations. - For dry-type cast resin transformers, XIAOWEI said it can add forced-air cross-flow fans and digital thermal controllers with RS485 communication. - The company said its thermal targets are rated winding temperature rise at 55°C or lower and hot-spot temperature rise at 65°C or lower under full load at high elevation. - XIAOWEI said its enclosure options include heavy-gauge cold-rolled steel, 304 or 316L stainless steel and hot-dip galvanized mounting structures. - The company said surface treatment can include shot blasting, phosphating and multi-layer electrostatic powder coating aligned with ISO 12944 C4 or C5-M standards. - XIAOWEI said enclosure ratings can be built to IP20, IP23, IP54 or IP55, along with NEMA 3R, NEMA 4 or NEMA 4X specifications. - The company said sealing and hardware options include nitrile or fluororubber gaskets, stainless steel hardware and baffled ventilation louvers. - XIAOWEI said its K-factor transformers are designed for non-linear loads such as VFDs, UPS systems, LED lighting power supplies and EV fast-charging stations. - The company said K-4, K-13 and K-20 models use double-sized neutral conductors, electrostatic copper shielding and strip-wound copper conductors. - XIAOWEI said its core assemblies use 45-degree mitered grain-oriented cold-rolled silicon steel laminations with structural clamping bands and vibration-damping neoprene pads. - The company said its manufacturing process includes 100% copper windings, certified silicon steel metallurgy, custom dimensional footprints and factory acceptance test documentation. - XIAOWEI said the factory can provide technical drawing reviews, 3D CAD modeling, custom terminal arrangement design and warranty coverage of 2 years or longer on dry-type models. - The company said it offers rapid global delivery schedules and flexible production for small-batch project orders. - XIAOWEI said it has 20 years of transformer engineering experience and certifications including ISO quality management, UL, CSA, CE and IEC. - The company listed its official portal for 3D CAD models, schematic diagrams, engineering type test reports and price quotations. - XIAOWEI also directed customers to its technical sales team for consultations, short-circuit withstand calculations, bushing arrangement help, seismic reports and voltage ratio calculations. - The company provided a phone number, +86 18662233449, and social media links on Facebook and TikTok.

Between the lines: - The announcement is less about a single product launch and more about XIAOWEI selling customization as the differentiator. - The emphasis on standards, test documentation and engineering support suggests the company is targeting buyers that must clear utility, industrial or project-specification approvals. - The repeated focus on harsh environments shows the strongest use case is infrastructure where failure costs are high and operating conditions are demanding.

What's next: - XIAOWEI is inviting customers to request CAD models, electrical schematics, type test reports and volume quotations through its sales channels. - The company says direct technical consultations are available for project-specific design and calculation support. - Future business appears tied to custom orders across energy, industrial and utility markets rather than mass-market transformer sales.

The bottom line: - XIAOWEI is betting that custom engineering, not standardized hardware, is what wins transformer deals in complex grid and industrial applications.
