Latin American projects span humid tropical lowlands, salt-exposed coastlines and high-altitude Andean sites, across grids that are 60Hz in some countries and 50Hz in others. Haocheng box substations and transformers are configured per site rather than supplied as a single standard build.
High humidity and heavy rainfall demand sealed enclosures, controlled ventilation and moisture-resistant insulation systems.
Coastal and port sites need anti-corrosion coating and sealed entries against salt-laden air.
Above 1000 m, reduced air density lowers cooling capacity and dielectric strength; rating is reviewed and derated accordingly.
Brazil, Mexico and others operate at 60Hz while others use 50Hz; voltage and frequency are configured per project.
Steel enclosure IP33~IP54, specified to IP54+ with anti-corrosion coating for humid, coastal or high-rainfall sites.
Dry-type SCB10/SCB11 preferred for indoor, fire-sensitive and humidity-controlled rooms; oil-immersed S11/S13 for outdoor duty.
50-2500 kVA with altitude derating applied; 50Hz or 60Hz configured per project, with the required LV voltage.
KYN28A-12 / HXGN HV chambers and GCK/GCS/MNS LV distribution per the single-line diagram.
Equipment is supplied to IEC standards with CE marked and CCC. Export documentation is provided, and we support local conformity work (for example INMETRO, NOM or IRAM frameworks) with the technical file and test reports required by the destination authority. Share your project parameters for selection.
Both are configured per project. Confirm country grid frequency and LV voltage at enquiry stage so the unit is built correctly.
Above 1000 m, cooling capacity and dielectric strength are reduced; the rating is reviewed and derated for the site altitude.
Dry-type SCB10/SCB11 is often preferred indoors for fire safety and humidity control; oil-immersed S11/S13 suits outdoor substations.
IP54+ enclosure with anti-corrosion coating and sealed gland entries against salt-laden air.
IEC-based test reports, CE marked and CCC documentation, export documents, plus technical file support for local certification.
