[ ГОСТ Р 51778-2001]
A panelboard as defined by the National Electrical Code is a single panel or a group of panel units designed for assembly in the form of a single panel; including buses, automatic overcurrent devices, and equipped with or without switches for the control of light, heat, or power circuits, designed to be placed in a cabinet or cutout box placed in or against a wall or partition and accessible only from the front.
Panelboards provide a compact and convenient method of grouping circuit switching and protective devices at some common point.
Panelboards may be of either the flush or the surface type (Fig. 4.125).
The flush type is used with concealed-wiring installations and has the advantage of not taking up space in the room by extending beyond the surface of the wall. Surface type boxes are used for installations employing exposed wiring.
The boxes are generally constructed of sheet steel, which must be not less than 0.053 in. (1.35 mm) in thickness.
The steel must be galvanized or be covered with some other protective coating to prevent corrosion.
Gutters are provided around the panelboards in cabinets to allow sufficient space for wiring (Figs. 4.125 and 4.126).
FIGURE 4.125 Panel boxes.
The Code requires that all cabinets which contain connections to more than eight conductors be provided with back or side wiring spaces. These wiring spaces must be separated from the panelboard or other devices in the cabinet by partitions so that they will be separate closed compartments, unless all wires are led from the cabinet at points directly opposite their terminal connections to the panelboard.

Cast resin transformers
Dry-type transformers, with one or more enclosed windings, are usually called cast resin transformers.
These types, due to developments in construction techniques, are more and more widely used because of their reliability, their lower environmental impact compared to oil transformers, and because they reduce the risks of fire and spreading polluting substances in the environment.
Medium-voltage windings, made with wire coils or, even better, insulated aluminium strips, are placed in a mould into which the epoxy resin is poured under vacuum, to avoid inclusions of gas in the insulation.
The windings are then enclosed in a cylindrical enclosure, which is totally sealed, mechanically strong and has a smooth surface which impedes both the deposit of dust and the action of polluting agents.
Low-voltage windings are generally made of a single aluminium sheet, the same height as the coil, insulated by suitable material and heat treatment.
Cast resin transformers use class F 155°C insulating material, allowing for a maximum temperature rise of 100°K.
[Legrand]Tрансформаторы с литой изоляцией
Сухие трансформаторы с одной или несколькими обмотками, залитыми компаундом, называют трансформаторами с литой изоляцией. Благодаря постоянному совершенствованию конструкции трансформаторы данного типа находят все более широкое применение, поскольку обладают высокой надежностью и более низким, по сравнению с масляными трансформаторами, воздействием на окружающую среду, а также меньшей опасностью возгорания и отсутствием выделения загрязняющих веществ в окружающее пространство.
Обмотки среднего (высшего) напряжения изготавливают из провода или, что еще лучше, из изолированной алюминиевой шины. Такие обмотки помещают в форму, в которую после вакуумирования подают эпоксидную смолу. Данная технология исключает наличие газа в изоляции. Затем обмотки помещают в герметичную механически прочную цилиндрическую оболочку с гладкой ровной поверхностью, предотвращающей скапливание пыли и загрязняющих веществ, оказывающих отрицательное воздействие.
Обмотки низшего напряжения, как правило, изготавливают из алюминиевой полосы такой же высоты, что и высота обмотки высшего напряжения. Обмотки низшего напряжения изолируют соответствующим материалом и подвергают тепловой обработке. Применяемая в трансформаторах в качестве изоляционного материала эпоксидная смола имеет класс нагревостойкости F, что соответствует температуре 155 °С. Это означает, что в процессе эксплуатации трансформатора допускается превышение температуры обмоток на 100 К.
