oil-immersed distribution solution designed for medium-voltage power\n          systems. It integrates the transformer body, high-voltage switching\n          and protection devices, low-voltage connection compartment, and\n          outdoor enclosure within a complete factory-assembled unit.\n        <\/p>\n\n        <p class=\"dhdl-three-phase-pad-overview-text\">\n          Its compact pad-mounted structure reduces installation space and\n          simplifies transportation, positioning, cable connection, and\n          maintenance. The product is suitable for industrial parks,\n          commercial facilities, urban distribution networks, factories,\n          residential developments, and utility power distribution projects.\n        <\/p>\n\n        <p class=\"dhdl-three-phase-pad-overview-text\">\n          The oil-immersed insulation and cooling system supports effective\n          heat dissipation and stable operation under continuous load\n          conditions. A secure compartment arrangement and weather-resistant\n          enclosure help protect the internal equipment from rain, wind,\n          dust, and other demanding outdoor conditions.\n
