Шкаф - защищенное НКУ, предназначенное для установки на полу
Safety enclosed boards are used for most new installations. Common terms used to designate equipment of this type are metal-enclosed switchgear and metal-clad switchgear.
Most safety enclosed boards are of the unit or sectional type. They consist of a combination of the desired number and type of standardized unit sections.
Each section is a standard factory-assembled combination of a formed steel panel and apparatus mounted on a steel framework.
Safety enclosed switchgear may be classified with respect to purpose of application as follows:
1. General medium- or high-voltage switchgear
2. Primary unit substations
3. Rectifier unit substations
4. Secondary unit substations or power centers
5. General low-voltage switchgear
6. Low-voltage distribution switchboards
7. Motor-control-center switchboards

overturn (limnology)
The circulation, especially in the fall and spring, of the layers of water in a lake or sea, whereby surface water sinks and mixes with bottom water; it is caused by changes in density differences due to changes in temperature, and is especially common wherever lakes are icebound in winter.
