In case of oil shortage, it is necessary to contact the production or installation and maintenance unit;<\/p>\n<p>&#8211; Cooling system: With large capacity transformers over 3500 kVA, there is usually a separating valve between the tank shell and the radiator. Before closing the power, the separating valve must be opened to allow the cooling oil to circulate between chassis and radiators;<\/p>\n<p>&#8211; Equipment such as pressure protection (safety valve with closed transformer and explosive discharge tube with open transformer), gas relay, and temperature measurement must ensure integrity, free from dust and grease.<\/p>\n<p>&#8211; Insulation test: When measuring insulation resistance, if the measured value is less than the parameter according to the machine history, the connecting conductors (including the ground wire) must be checked again with the transformer. Check that these connectors are completely isolated. If the connecting conductors have been isolated, but when checking the resistance value is still less than the parameter according to the machine history, the energizing must stop and notify the manufacturer or distributor for remedial measures.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Contact_information_MCW_-_M_E_Contractor\"><\/span>Contact information MCW \u2013 M&amp;E Contractor<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Headquarter:<\/strong> No. 6\/165C Xuan Thuy, Cau Giay District, Hanoi<\/p>\n<p><strong>Website:<\/strong> https:\/\/mcw663.com\/<\/p>\n<p><strong>Hotline:<\/strong> 02422121212 \u2013 0945213595<\/p>\n<p><strong>Email:<\/strong> kd@cokhimcw663.com<\/p>\n<p><strong>Facebook:<\/strong>\u00a0<a href=\"https:\/\/www.facebook.com\/p69nhathaucodien\">https:\/\/www.facebook.com\/p69nhathaucodien<\/a><\/p>\n<p><strong>LinkedIn:<\/strong>\u00a0<a href=\"https:\/\/www.linkedin.com\/in\/congtyp69\/\">https:\/\/www.linkedin.com\/in\/congtyp69\/<\/a><\/p>\n<p><strong>Youtube:<\/strong> <a href=\"https:\/\/www.youtube.com\/channel\/UCOUwCnE5iGj8iqe_ZIUM7oA\">https:\/\/www.youtube.com\/channel\/UCOUwCnE5iGj8iqe_ZIUM7oA<\/a><\/p>\n\n\n<div class=\"kk-star-ratings kksr-auto kksr-align-left kksr-valign-bottom\"\n    data-payload='{&quot;align&quot;:&quot;left&quot;,&quot;id&quot;:&quot;2394&quot;,&quot;slug&quot;:&quot;default&quot;,&quot;valign&quot;:&quot;bottom&quot;,&quot;ignore&quot;:&quot;&quot;,&quot;reference&quot;:&quot;auto&quot;,&quot;class&quot;:&quot;&quot;,&quot;count&quot;:&quot;3&quot;,&quot;legendonly&quot;:&quot;&quot;,&quot;readonly&quot;:&quot;&quot;,&quot;score&quot;:&quot;5&quot;,&quot;starsonly&quot;:&quot;&quot;,&quot;best&quot;:&quot;5&quot;,&quot;gap&quot;:&quot;5&quot;,&quot;greet&quot;:&quot;Rate this post&quot;,&quot;legend&quot;:&quot;5\\\/5 - (3 votes)&quot;,&quot;size&quot;:&quot;24&quot;,&quot;width&quot;:&quot;142.5&quot;,&quot;_legend&quot;:&quot;{score}\\\/{best} - ({count} {votes})&quot;,&quot;font_factor&quot;:&quot;1.25&quot;}'>\n            \n<div class=\"kksr-stars\">\n    \n<div class=\"kksr-stars-inactive\">\n            <div class=\"kksr-star\" data-star=\"1\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"2\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"3\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"4\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" data-star=\"5\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n    \n<div class=\"kksr-stars-active\" style=\"width: 142.5px;\">\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n            <div class=\"kksr-star\" style=\"padding-right: 5px\">\n            \n\n<div class=\"kksr-icon\" style=\"width: 24px; height: 24px;\"><\/div>\n        <\/div>\n    <\/div>\n<\/div>\n                \n\n<div class=\"kksr-legend\" style=\"font-size: 19.2px;\">\n            5\/5 - (3 votes)    <\/div>\n    <\/div>","protected":false},"excerpt":{"rendered":"<p>Transformer is one of the high value products.
