High-quality insulating materials and a robust tank structure provide reliable insulation and mechanical protection.<\/p>\n<p class=\"isSelectedEnd\">The transformer can be customized for different grid voltage levels, power capacities, environmental conditions, installation methods, and project standards. This makes it suitable for medium- and high-voltage substations, industrial power systems, renewable energy projects, and utility distribution networks.<\/p>\n<p class=\"isSelectedEnd\">ZISHENG applies process control from raw-material selection and component manufacturing through assembly and final testing. Each transformer is subject to performance and electrical tests before shipment to ensure compliance with the agreed technical specifications.<\/p>\n<h3>Customization<\/h3>\n<p class=\"isSelectedEnd\">All technical parameters can be customized according to the project requirements, including:<\/p>\n<ul data-spread=\"false\">\n<li>Capacity<\/li>\n<li>Primary and secondary voltage<\/li>\n<li>Frequency<\/li>\n<li>No-load and load losses<\/li>\n<li>Impedance<\/li>\n<li>Vector group<\/li>\n<li>Tap range and tap-changer type<\/li>\n<li>Cooling method<\/li>\n<li>Winding material<\/li>\n<li>Insulation level \/ BIL<\/li>\n<li>Tank and enclosure configuration<\/li>\n<li>Protection and monitoring accessories<\/li>\n<li>Applicable international or local standards<\/li>\n<\/ul>\n<p>The technical data above is for reference only.
