2 склоны скалистые
gentle runnels (водотоки с пологими краями) or rocky slopes and adjacent portions of the valley bottom.In the study area, the angle of slope averaged 35°, with continuous grass cover except on rock outcrops and boulders. Grass height was mostly c. 50 cm, but somewhat shorter, averaging 350 on steep slopes, and with scattered, even shorter patches .The arctic land is not characterized everywhere by low tundra, for a large part is mountainous. In some regions strongly denuded areas of old mountain chains now form undulating peneplains, while in other sections the country is extremely montainous, consisting of sky-high towering alps with steep slopes and majestic snow-capped peaks and ridges .Русско-английский словарь по этологии (поведению животных) > склоны скалистые

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
