Guizhou Delong Electrical Group Co.,Ltd

We are a manufacturing plant, not a trading company. We have a fully equipped production line for the production of transformers, all key technological processes are carried out in-house: core cutting and fusion, winding winding, active part assembly, general assembly and commissioning tests - all this is carried out in our own workshops. We especially emphasize that the two most important components - the core and windings - are manufactured by us independently, without outsourcing or involving subcontractors. We provide full traceability of both materials and the production process. Certain purchased components, such as bushings and tap switches, are supplied by external partners, but enter production only after full incoming inspection. We control the quality of transformers at the core precisely because all the key links are in our hands.

All products we export have a full package of documents and are fully certified. We hold major certifications that are widely recognized in the international market, including: ISO Certificate, CE Certificate, EAC Certificate, GOST Certificate.

In addition, the company is certified to ISO 9001 Quality Management, ISO 14001 Environmental Management and ISO 45001 Occupational Health and Safety Management Systems. This ensures that our production processes are standardized, management is strictly regulated and production is in no way “artisanal”. We are able to consistently and continuously supply high quality products.
