Industrial Automation – A U.S. automotive plant replaced legacy delta‑wye kits with our custom 5 MVA units, reducing line‑stop time by 42% and saving $120 k annually.
Medical Equipment – A leading MRI manufacturer adopted our low‑noise, shielded design, achieving compliance with IEC‑60601‑1 and cutting electromagnetic interference by 67%.
Renewable Energy – A solar‑farm developer integrated our high‑efficiency 2 MVA delta‑wye transformer, increasing overall plant efficiency by 3.8% and meeting ISO‑50001 energy‑management standards.
Customer Testimonial: “Switching to Xinchangda’s delta‑wye kits cut our power‑loss by 35% and the on‑site support cut installation time from 7 days to 2 days. The ROI was realized in just 4 months.” – James L., Senior Procurement Manager, GE Power
All products carry CE, FCC, RoHS, ISO 9001, and CB certifications. Our factory follows ISO 14001 environmental standards and is audited annually by SGS.

A Delta‑Wye (Δ‑Y) connection links a three‑phase delta‑connected source to a wye‑connected load (or vice‑versa). It provides a phase‑shift of 30°, balances line currents, and is ideal for motor drives, HVAC, and renewable‑energy converters where voltage transformation and neutral availability are required.
Yes. Our R&D team (10 engineers) can design custom ratios from 0.5 kVA up to 10 MVA, with stainless‑steel, aluminum, or epoxy enclosures to meet IP‑rating, size, and weight constraints.
Standard production is 2 weeks. Express (48 h) is available for urgent orders. We ship via DHL, UPS, or ocean freight with full customs documentation (CE, FCC, RoHS). Our warehouse in Los Angeles provides same‑day dispatch for stocked SKUs.
We provide a free engineering sample (up to 2 kVA) with a 30‑day performance guarantee. If the unit does not meet the agreed specifications, we will replace it at no extra cost.
Because we own the full production line (14 automated lines), we cut middle‑man margins and pass savings directly to you – typically 20‑25% lower than market averages while maintaining ISO‑9001 quality.
Limited‑time offer: **Free engineering sample** for orders placed before 31 May 2026. Stock is limited to 500 units.
