It mainly uses high-quality cold-rolled sheet metal as the enclosure, processed through cutting, bending, welding, and other processes, with a reasonable structure and beautiful appearance. The equipment is primarily composed of high-voltage load switch, load switch-fuse combination appliance, and other electrical components. The busbar system adopts premium raw copper busbars, with reliable insulation treatment and excellent conductivity. The main switch and fuse are equipped with reliable anti-misoperation mechanical interlock devices to ensure personal safety.<\/p>\n    <p>The equipment can be used in various power systems such as industrial and mining enterprises, residential communities, schools, parks, etc. It can be configured with a single or dual power supply, and the electrical schematic can be designed according to user requirements. It meets the requirements of IEC60298 and GB3906 standards.<\/p>\n    <p>The equipment has an open structure, good ventilation conditions, high reliability, and is easy to install and maintain.<\/p>\n  <\/div>\n<\/div>\n\n<!-- \u2500\u2500 Technical Parameters \u2500\u2500 -->\n<div class=\"mac-card\">\n  <h2 class=\"mac-section-title\">Technical Parameters<\/h2>\n  <div class=\"mac-table-wrap\">\n    <table class=\"mac-param-table\">\n      <thead>\n        <tr>\n          <th>Parameters<\/th>\n          <th>Unit<\/th>\n          <th>Parameter<\/th>\n        <\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td>Rated voltage<\/td><td class=\"unit-col\">kV<\/td><td>12<\/td><\/tr>\n        <tr><td>Rated frequency<\/td><td class=\"unit-col\">Hz<\/td><td>50<\/td><\/tr>\n        <tr><td>Rated current<\/td><td class=\"unit-col\">A<\/td><td>630<\/td><\/tr>\n        <tr><td>Rated short-time withstand current<\/td><td class=\"unit-col\">kA<\/td><td>20<\/td><\/tr>\n        <tr><td>Rated peak withstand current<\/td><td class=\"unit-col\">kA<\/td><td>50<\/td><\/tr>\n        <tr><td>Power frequency withstand voltage<\/td><td class=\"unit-col\">kV<\/td><td>42<\/td><\/tr>\n        <tr><td>Lightning impulse withstand voltage<\/td><td class=\"unit-col\">kV<\/td><td>75<\/td><\/tr>\n        <tr><td>Rated short-circuit breaking current<\/td><td class=\"unit-col\">kA<\/td><td>20<\/td><\/tr>\n        <tr><td>Rated short-circuit closing current<\/td><td class=\"unit-col\">kA<\/td><td>50<\/td><\/tr>\n        <tr><td>Rated transfer current<\/td><td class=\"unit-col\">A<\/td><td>1700<\/td><\/tr>\n        <tr><td>Rated cable charging breaking current<\/td><td class=\"unit-col\">A<\/td><td>10<\/td><\/tr>\n        <tr><td>Mechanical life<\/td><td class=\"unit-col\">times<\/td><td>3000<\/td><\/tr>\n        <tr><td>Protection class<\/td><td class=\"unit-col\">\u2014<\/td><td>IP3X<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n<\/div>\n\n<!-- \u2500\u2500 Structure Diagram \u2500\u2500 -->\n<div class=\"mac-card\">\n  <h2 class=\"mac-section-title\">Structure Diagram<\/h2>\n  <div class=\"mac-diagram\">\n    <div class=\"mac-diagram-legend\">\n      <div class=\"mac-legend-title\">Components<\/div>\n      <div class=\"mac-legend-item\"><span class=\"mac-legend-num\">1<\/span><span>Metering room<\/span><\/div>\n      <div class=\"mac-legend-item\"><span class=\"mac-legend-num\">2<\/span><span>Load switch mechanism<\/span><\/div>\n      <div class=\"mac-legend-item\"><span class=\"mac-legend-num\">3<\/span><span>Cable room<\/span><\/div>\n      <div class=\"mac-legend-item\"><span class=\"mac-legend-num\">4<\/span><span>Busbar room<\/span><\/div>\n      <div class=\"mac-legend-item\"><span class=\"mac-legend-num\">5<\/span><span>Busbar<\/span><\/div>\n    <\/div>\n    <div class=\"mac-diagram-img\">\n      <img decoding=\"async\" src=\"https:\/\/haochengcompany.com\/wp-content\/uploads\/2026\/06\/123.webp\" alt=\"Modular AC Metal Enclosed Ring Main Unit Diagram\">\n    <\/div>\n  <\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Home \u9875\u9762 Modular AC Metal Enclosed Ring Main Unit Customizable The modular AC metal enclosed switchgear is a safe and reliable power distribution equipment suitable for indoor installation.
