The trend towards prefabrication has been witnessing an upward trend for more than a decade.<\/p>\n<h2 id=\"applications\">Key Application Areas<\/h2>\n<p>There are four main application sectors for box-type substations.<\/p>\n<ul>\n<li>Urban and commercial distribution. These substations ensure the operation of residential districts, commercial centers, office high-rise buildings, and street grids. Quick installation and compact design of these substations make them ideal for urban areas.<\/li>\n<li>Industrial parks. Here each factory or group of factories receives one substation. The capacity of the box-type substation can be increased from 400 kVA to 1,600 kVA.<\/li>\n<li>Plants generating renewable energy. Solar plants normally employ a lot of box-type substations to keep inverters in operation. Wind power plants implement this technology to connect electrical turbines to grid lines.<\/li>\n<li>Rural electrification. In rural areas, box-type substations cover electricity demand from villages and agricultural businesses at rather low costs.<\/li>\n<\/ul>\n<p>In all the cases, the substation performs the same essential function of electric energy hub: it receives energy supply, processes it in a required way, secures the supply in the grid, and provides the appropriate electricity consumption \u2014 all inside the substation.<\/p>\n<h2 id=\"standards\">Standards and Testing<\/h2>\n<p>The standards that define box-type substation quality and safety:<\/p>\n<table>\n<thead>\n<tr>\n<th>\u0645\u0639\u064a\u0627\u0631<\/th>\n<th>\u0627\u0644\u0646\u0637\u0627\u0642<\/th>\n<th>Key Requirement for Buyers<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>IEC 62271-202<\/td>\n<td>Prefabricated transformer substations<\/td>\n<td>Complete-unit type tests: temperature rise, short circuit, dielectric<\/td>\n<\/tr>\n<tr>\n<td>IEC 60076<\/td>\n<td>Power transformers<\/td>\n<td>Transformer rating, losses, routine\/type tests<\/td>\n<\/tr>\n<tr>\n<td>IEC 60529<\/td>\n<td>IP enclosure protection<\/td>\n<td>IP54 minimum for outdoor units; IP55 where water spray risk exists<\/td>\n<\/tr>\n<tr>\n<td>IEC 62271-200<\/td>\n<td>MV metal-enclosed switchgear<\/td>\n<td>RMU safety and test requirements<\/td>\n<\/tr>\n<tr>\n<td>IEEE C57.12.27<\/td>\n<td>Pad-mount equipment integrity (North America)<\/td>\n<td>Dead-front construction and tamper resistance<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>One of the major tests done on an enclosure is the IEC 62271-202 temperature-rise test which ensures the transformer does not exceed insulation temperature limits while operating at full capacity.

For instance, a 400 to a 1000 kVA transformer can cost you anywhere between $7,000 to $33,000. Similarly, a transformer within the 1,600 to 2,500 kVA size can range from $24,000 to $60,000. Stainless steel as a material can cost either 15-30% of the total cost of the transformer, dry-type units ask for 10-20% surcharge while monitoring upgrades will cost you $800-$3,000.<\/p>\n<h3>\u0643\u0645 \u0645\u0646 \u0627\u0644\u0648\u0642\u062a \u062a\u0633\u062a\u063a\u0631\u0642 \u0639\u0645\u0644\u064a\u0629 \u0627\u0644\u062a\u062b\u0628\u064a\u062a\u061f<\/h3>\n<p>In general, the installation period of a concrete pad is around 2 to 5 days, including crane usage, installation, bolting down, cable termination, and commissioning process. On the contrary, a conventional substation requires four to twelve weeks of installation. Thanks to a factory testing approach, commissioning issues are rare, provided that the cables on site are laid and the pad has been built according to the supplier\u2019s recommendation.<\/p>\n<h3>Can a box-type substation be relocated or upsized later?<\/h3>\n<p>Indeed \u2014 this is one of its key benefits. A transformer can be transported, relocated, and powered up at a site, while a larger unit can be installed in the enclosure with a smaller transformer. This flexibility works well for industries and rapidly developing cities.<\/p>\n<h3>What is the difference between a box-type substation and a pad-mount transformer?<\/h3>\n<p>They are regional relatives. The box substation (IEC 62271-202) incorporates medium voltage switchgear, transformer, and low voltage switchgear into a single unit and is mostly found all over Europe, Asia, the Middle East, and Africa. The pad transformer (IEEE C57.12, North America), on the other hand, is traditionally a stand-alone unit with dead-front connections on the pad.<\/p>\n<h3>What tests should I require before accepting a box-type substation?<\/h3>\n<p>The transformer must undergo routine testing in accordance with IEC 60076, as well as switchgear testing and complete unit testing according to IEC 62271-202 when needed. This couple of things should include temperature rise tests when the case is provided, short-circuit resistance tests, and dielectric testing. If the order is for exported materials, make sure to request that factory test observation and inspection before shipment are both conducted.<\/p>\n<h2 id=\"references\">\u0627\u0644\u0645\u0631\u0627\u062c\u0639<\/h2>\n<ul>\n<li><a href=\"https:\/\/webstore.iec.ch\" rel=\"nofollow noopener\" target=\"_blank\">IEC 62271-202 \u2014 High-voltage switchgear: Prefabricated transformer substations<\/a> \u2014 the governing standard for box-type substation design, safety, and type testing.<\/li>\n<li><a href=\"https:\/\/iec.ch\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60076 series \u2014 Power transformers<\/a> \u2014 the base standard for the transformers installed inside box-type units.<\/li>\n<li><a href=\"https:\/\/webstore.iec.ch\" rel=\"nofollow noopener\" target=\"_blank\">IEC 62271-200 \u2014 MV metal-enclosed switchgear<\/a> \u2014 requirements for the RMU and breaker compartments.<\/li>\n<li><a href=\"https:\/\/webstore.iec.ch\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60529 \u2014 Degrees of protection provided by enclosures (IP Code)<\/a> \u2014 defines IP54\/IP55 enclosure ratings.<\/li>\n<li><a href=\"https:\/\/standards.ieee.org\" rel=\"nofollow noopener\" target=\"_blank\">IEEE C57.12.27 \u2014 Pad-mounted equipment enclosure integrity<\/a> \u2014 North American dead-front and tamper-resistance requirements.<\/li>\n<li><a href=\"https:\/\/www.nema.org\" rel=\"nofollow noopener\" target=\"_blank\">NEMA \u2014 pad-mount distribution transformer standards<\/a> \u2014 application and rating guidance for compact substation equipment in the Americas.<\/li>\n<li><a href=\"https:\/\/subian-electric.com\/ar\/\" rel=\"nofollow\">Jiangsu Subian Electric Power \u2014 official site<\/a> \u2014 manufacturer and exporter of IEC 62271-202 box-type substations.<\/li>\n<\/ul>\n<h2 id=\"conclusion\">\u0627\u0644\u062e\u0627\u062a\u0645\u0629<\/h2>\n<p>The box-type substations are called an energy hub in modern power distribution because of their superior speed, economical value, adaptability, and good factory quality over traditional substation installations.
