Frequently Asked Questions

What types of transformers and substations does QDTB manufacture?

QDTB manufactures a comprehensive range of power equipment including dry-type transformers, oil-immersed transformers, amorphous alloy transformers, prefabricated substations (compact substations, package substations, pad-mounted substations), switchgear, ring main units, reactors, and cable branch boxes.

What is the difference between a prefabricated substation and a compact substation?

Prefabricated substation, compact substation, package substation, and pad-mounted substation are different terms for similar factory-assembled power distribution units. European-type units are commonly called compact substations, while American-type units are often called pad-mounted substations. All integrate transformer, switchgear, and distribution in one enclosure.

What certifications do your products have?

All QDTB products are ISO 9001 certified and carry CE marking. Our transformers comply with IEC standards (IEC 60076, IEC 61330, IEC 62271) and Chinese national standards (GB 1094, GB/T 17467, GB 3906). We also support IEEE standards for North American markets.

Can you customize products to specific requirements?

Yes, QDTB supports full OEM/ODM customization. We can adjust capacity, voltage ratios, cooling methods, enclosure types, and protection levels to match your project specifications. Our engineering team provides technical consultation for optimal product selection.

What is the typical lead time for orders?

Standard products ship within 15-25 working days. Custom or large-capacity units may require 30-45 working days. We maintain stock of popular models for urgent requirements.
