Dense on board electrical equipment creates complex electromagnetic environments that readily produce power quality issues including harmonic interference, inrush currents and voltage surges, triggering hidden troubles such as on board electric control faults, equipment abnormal noise and component aging. Special purpose transformers and reactors for high speed EMUs act as key supporting components of on board power systems, performing core functions such as voltage conversion, galvanic isolation, harmonic suppression, current stabilization and electromagnetic compatibility protection. Custom developed against strict industry standards for high reliability, high safety, vibration resistance, low loss and strong electromagnetic compatibility for high speed EMUs, our products deliver superior stability, ultra low noise, wide range temperature tolerance and strong anti interference performance compared with general purpose industrial products. They eliminate operational hidden dangers of on board electrical equipment and guarantee safe, smooth and efficient full journey operation of high speed EMUs.<\/p>\n<p><a class=\"btn-more\" href=\"\/rail-transit-high-speed-emu-case\/\">More<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<section id=\"related-products\" class=\"related-products-section\">\n<div class=\"section-header\">\n<h2 data-text=\"Related Products\">Related Products<\/h2>\n<\/div>\n<div class=\"solution-related-wrap\"><div class=\"woocommerce columns-4 \"><ul class=\"products columns-4\">\n<li class=\"desktop-align-left tablet-align-left mobile-align-left product type-product post-1092 status-publish first instock product_cat-ac-output-line-reactor product_cat-reactor-inductors-chokes has-post-thumbnail shipping-taxable product-type-simple\">\n\t<a href=\"https:\/\/www.lstransformer.com\/ja\/product\/ac-output-reactor-2\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><img fetchpriority=\"high\" decoding=\"async\" width=\"400\" height=\"400\" src=\"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/10-1-400x400.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"AC Output Reactor\" srcset=\"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/10-1-400x400.jpg 400w, https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/10-1-100x100.jpg 100w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><h2 class=\"woocommerce-loop-product__title\">AC Output Reactor<\/h2>\n<\/a><a href=\"https:\/\/www.lstransformer.com\/ja\/product\/ac-output-reactor-2\/\" aria-describedby=\"woocommerce_loop_add_to_cart_link_describedby_1092\" data-quantity=\"1\" class=\"button product_type_simple\" data-product_id=\"1092\" data-product_sku=\"\" aria-label=\"Read more about&ldquo;AC Output Reactor&rdquo;\" rel=\"\" data-success_message=\"\">\u3082\u3063\u3068\u8aad\u3080<\/a>\t<span id=\"woocommerce_loop_add_to_cart_link_describedby_1092\" class=\"screen-reader-text\">\n\t\t\t<\/span>\n<\/li>\n<li class=\"desktop-align-left tablet-align-left mobile-align-left product type-product post-1090 status-publish instock product_cat-energy-feedback-reactor product_cat-reactor-inductors-chokes has-post-thumbnail shipping-taxable product-type-simple\">\n\t<a href=\"https:\/\/www.lstransformer.com\/ja\/product\/three-phase-energy-feedback-reactor\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><img decoding=\"async\" width=\"400\" height=\"400\" src=\"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/4-1-400x400.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"Three-phase Energy Feedback Reactor\" srcset=\"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/4-1-400x400.jpg 400w, https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/4-1-100x100.jpg 100w, https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/4-1-150x150.jpg 150w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><h2 class=\"woocommerce-loop-product__title\">Three-phase Energy Feedback Reactor<\/h2>\n<\/a><a href=\"https:\/\/www.lstransformer.com\/ja\/product\/three-phase-energy-feedback-reactor\/\" aria-describedby=\"woocommerce_loop_add_to_cart_link_describedby_1090\" data-quantity=\"1\" class=\"button product_type_simple\" data-product_id=\"1090\" data-product_sku=\"\" aria-label=\"Read more about&ldquo;Three-phase Energy Feedback Reactor&rdquo;\" rel=\"\" data-success_message=\"\">\u3082\u3063\u3068\u8aad\u3080<\/a>\t<span id=\"woocommerce_loop_add_to_cart_link_describedby_1090\" class=\"screen-reader-text\">\n\t\t\t<\/span>\n<\/li>\n<\/ul>\n<\/div><\/div>\n<\/section>\n<\/section>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Rapid Transit Applications of transformers and reactors: Auxiliary Power Supply System; Auxiliary Inverter; Emergency Ventilation; Emergency Braking; and Vehicle power supply.
