Transformers for Data Centers
Cast-resin dry-type, pad-mounted and medium-voltage transformers built for hyperscale and edge data centers — UL / IEC certified, shipped factory-direct from China in 30–45 days.
- ✓ Full chain: 110/220 kV intake → MV → LV from one partner
- ✓ 30–45 day lead time vs 120+ weeks from US/EU mills
- ✓ UL / cUL, IEC 60076-11, CSA and DOE-efficiency compliant
- ✓ Backed by senior power-system engineers (10+ yrs in utilities)
Data centers need reliable, fire-safe power distribution at megawatt scale. Voltspan supplies the FULL power chain for data centers — from the 110/220 kV utility intake down to medium- and low-voltage distribution: cast-resin dry-type units for indoor halls, pad-mounted transformers for outdoor yards, packaged substations, and high-voltage intake transformers. All factory-direct from China with fast lead times while US/EU lead times stretch past two years, and backed by senior power-system engineers with 10+ years in utilities.

Cast-resin dry-type transformers are preferred inside data halls because they are fire-safe, low-maintenance and contain no oil. Pad-mounted and oil-immersed units are used for outdoor medium-voltage distribution. Voltspan supplies all three to IEC and ANSI/UL standards.
Voltspan delivers most data-center transformers in 30–45 days after drawing approval, compared with 120+ weeks now quoted by many US and European manufacturers.
Yes. Units are available UL / cUL listed, built to IEC 60076-11, and compliant with US DOE efficiency standards — with full factory test reports for each order.
