FACTORY

Our manufacturing base covers the full production chain for switchgear and power transformers — from silicon steel core stacking and copper winding to panel assembly, insulation treatment, and full-range electrical testing. The facility is organized around project-based production rather than batch output, with parallel production lines for medium voltage switchgear, low voltage panels, oil immersed transformers, and dry type transformers. Every unit passes through the same quality control pipeline: incoming material inspection, in-process verification, final acceptance testing, and packaging audit before shipment. Standard configurations ship within 30 days; complex custom builds complete in 45 to 60 days.

STELLAR has built deep engineering capability through decades of product development, standard participation, and academic collaboration. Our R&D team holds over 160 authorized patents, including 35 invention patents, and has participated in the drafting of more than 25 national and industry standards for switchgear and transformer equipment. We maintain ongoing technical partnerships with leading Chinese engineering universities and power research institutes, including collaborations on switchgear design optimization, transformer core loss reduction, and insulation material innovation. Our facility operates a national-level post-doctoral research station, and has been recognized as a national high-tech enterprise, a national green factory, and a national intellectual property advantage enterprise. This technical depth is why our engineers can review your single-line diagram and come back with solutions, not just quotations.
