Adopting advanced solid insulation technology, the transformer abandons all liquid insulating and cooling materials. Its internal windings are fully encapsulated with high-purity epoxy resin through vacuum pouring and high-temperature curing process, forming an integrated solid insulation structure that effectively shields the core and coils from external environmental interference.<\/p>\n<p>The integral epoxy resin encapsulation endows the transformer with excellent electrical insulation performance, as well as strong resistance to moisture, dust, chemical contaminants and mechanical impact. The solid and compact structural design eliminates the hidden dangers of liquid leakage, insulation aging and structural looseness existing in traditional oil-filled transformers, ensuring long-term stable and reliable operation of the equipment.<\/p>\n<p>Compared with conventional liquid-filled transformers, our <a href=\"https:\/\/shenhengglobal.com\/de\/transformer\/\">epoxy cast resin dry-type transformers<\/a> have obvious comprehensive advantages. The optimized structural design makes the equipment smaller in size and lighter in weight, which greatly saves installation space and reduces transportation and installation costs. With no hazardous insulating liquid inside, the transformer produces no oil leakage pollution, fully complying with global environmental protection and green engineering standards. In addition, it features excellent fire resistance and flame retardant properties, which can effectively avoid fire and explosion risks, making it the preferred power equipment for scenarios with high fire safety requirements.<\/p>\n<p>Widely adaptable to diversified application scenarios, this three-phase dry-type transformer is extensively used in industrial factory power distribution, commercial building power supply, urban grid engineering, new energy renewable energy systems, rail transit and transportation power support systems, meeting the power supply needs of various medium and high-standard engineering projects.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/shenhengglobal.com\/wp-content\/uploads\/2026\/06\/1.-3-Phase-Cast-Resin-Dry-Type-Transformer.webp\" alt=\"11-kV-Drehstrom-Gie\u00dfharz-Trockentransformator\" \/><\/p>\n<h2>3 Phase Dry Type Transformer Sizes<\/h2>\n<p>A <strong>Dreiphasen-Trockentransformator<\/strong> is usually used to step down medium voltage such as 11kV to 400V or 415V low voltage.<\/p>\n<div class=\"scroll\">\n<table>\n<thead>\n<tr>\n<th>Model<\/th>\n<th>Common Voltage<\/th>\n<th>Typical Use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>500KVA<\/td>\n<td>11kV \/ 400V, 415V<\/td>\n<td>Small factories, buildings, HVAC systems<\/td>\n<\/tr>\n<tr>\n<td>1000KVA<\/td>\n<td>11kV \/ 400V, 415V<\/td>\n<td>Medium factories, malls, hospitals<\/td>\n<\/tr>\n<tr>\n<td>1500KVA<\/td>\n<td>11kV \/ 400V, 415V<\/td>\n<td>Large plants, infrastructure, data centers<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2><\/h2>\n<h2>Key Features And Benefits<\/h2>\n<p><strong>High Safety<\/strong><\/p>\n<p>Dry type cast resin transformers do not use oil, reducing fire risk and avoiding oil leakage problems.<\/p>\n<p><strong>Low Maintenance<\/strong><\/p>\n<p>No oil testing or replacement is required.
