Colombia Market Focus

Factory-Direct Oil-Immersed Distribution Supply

XinHuan is a China-based power transformer manufacturer exporting directly to Colombia via the Port of Buenaventura and Cartagena. We manufacture 60Hz oil-immersed distribution transformers and dry-type units engineered to comply with the Colombian RETIE (Reglamento Técnico de Instalaciones Eléctricas) safety standards and ANSI/IEEE grid requirements.

We supply 15kVA to 3000kVA transformers across Colombia's primary medium-voltage distribution ratings (13.2kV, 11.4kV, and 34.5kV) with 208V/120V or 240V/120V secondary outputs. Our factory specializes in heavy-duty pole-mounted units for rural grids and pad-mounted substations for urban development in Bogota, Cali, and Medellin.
