About Milestone Electrical

Milestone (Xiong’an) Electrical Technology Co., Ltd. is a transformer engineering and manufacturing company based in Xiong’an New Area, Hebei, China. Established in 2026, the company supports power generation, utility, EPC, oil and gas, mining, and industrial projects with transformer equipment and project-related technical services.
Milestone’s core product portfolio includes power transformers, distribution transformers, oil-immersed transformers, dry-type transformers, and compact substations. Product configurations are reviewed against each project’s electrical duty and site conditions. Relevant parameters may include primary and secondary voltage, rated capacity, frequency, phase, vector group, impedance, loss requirements, cooling method, tap changer, insulation level, installation arrangement, and environmental conditions.
The company supports buyers through transformer selection, specification review, RFQ clarification, engineering coordination, manufacturing, testing documentation, and export documentation. By reviewing technical requirements and supply boundaries early, Milestone aims to help project teams reduce specification gaps, clarify quotation scope, and compare proposals on a more consistent basis.
The engineering team uses electromagnetic, thermal, and mechanical simulation methods to support design decisions. Depending on the project requirements, material and configuration options may include low-loss silicon steel, specified winding materials, suitable insulating liquids, and project-appropriate cooling and structural arrangements. Applicable IEC or GB requirements, test scope, and acceptance criteria should be defined in the project specification and confirmed in the technical proposal.
Milestone’s priority markets include Chile and other South American markets, the United Arab Emirates, Indonesia, and Nigeria. The company provides ISO 9001 quality management system information and CE conformity documentation for applicable products; the exact certificate scope and covered models should be checked against the current documents. Buyers can begin a technical review by sharing a single-line diagram, key electrical ratings, applicable standards, site conditions, and required supply scope.
