About Voltspan

Voltspan is a China-based transformer manufacturer and one-stop global sourcing partner. We supply the full range — pole-mounted, pad-mounted, oil-immersed distribution, dry-type (cast resin), box substations, new-energy transformers and power transformers up to 1000 kV.

What sets us apart is engineering depth: our team includes power-utility engineers with 10+ years of field experience, and we work directly with China's top-tier transformer plants. That means correct specifications the first time, genuine certifications (UL / CE / IEC 60076), and factory-direct pricing — without the giant-brand premium.

We ship worldwide with FOB China pricing and 30–45 day lead times, and we support buyers in North America, Europe, the Middle East, Africa, South and Southeast Asia.
