When selecting the installation site, consider the following requirements at least:
• Ambient and geological conditions, such as stress wave emissions, the level of
underground water table and etc. should be taken into account.
• Far away from strong vibration, strong noise source and strong electromagnetic
interference area.
• The ambient environment should be dry, well ventilated, and far away from inflammable
materials.
• The ambient environment should be far away from dust, soot, harmful gases and the
production or storage of corrosive, flammable, explosive places.
• The site location shall not be in a low-lying area and the site level shall be higher than
the historical high water level in the area.
• Good soil condition, solid ground, no rubber soil, soft soil and other adverse geological
conditions, do not choose the ground which is easy to get into water and easy to sink .
• The installation site should take the ventilation into account.
• Choose the open position, to ensure that there is no obstacles in 10 meters from the
equipment surrounding.
• Keep at least 50 meters away from residential areas to avoid noise pollution.
• The ground at the installation site must be compacted enough. Relative compaction of
the ground should be equal to or greater than 98%. Otherwise, take proper methods to
strengthen the ground.
5.3.2 Recommended Foundation Construction Plan
The following conditions must be fulfilled:
• The bottom of the foundation should be firm enough.
• The foundations must be suitable for the weight of the MV Station.
• The foundation should be higher than the pea gravel ground on site to prevent the rain
from damaging the base or penetrating into the MV Station.
• Sufficient cross-sectional area and depth of the foundation should be maintained. The
depth is designed according to local soil conditions.
• Cable route should be taken into account.
