Huawei LUNA2000-2.0MWH Series - Foundation Requirements

● The preceding clearance requirements are for reference only in terms of
installation and O&M. The clearances must also comply with local re control
requirements.
3.3 Foundation Requirements
NO TE
The foundation layout design should meet the space requirements for ESS installation and
O&M. The design institute can contact local Huawei pre-sales engineers to obtain the
drawings about the foundation.
Before installation, build a concrete platform and trenches on the selected ground.
The foundation construction requirements are as follows:
● The dimensions of the foundation should meet the installation and bearing
requirements of the equipment.
● The average foundation strength should exceed 100 kg/cm
2
.
● The horizontal error between the foundation and the contact surface of the
equipment should be less than 5 mm.
● The ground resistance for the equipment should be less than or equal to 0.1
ohm.
● The ESS uses bottom cabling. Cables need to be pre-buried under the control
unit cabin.
● The inner diameter of the protective tube should not be less than 1.5 times of
the outer diameter of the cable (including the protective layer).
● The foundation should meet the local drainage requirements for the local
historical maximum rainfall. Drained water should be disposed of in
accordance with local laws and regulations.
● A cable trench (if any) cannot be used for drainage. Fire retardant sealing
should be implemented at cable holes (such as holes through partition walls
and
oors).
Check Item
No.
Check Item Acceptance Criteria
1 Cabling space
at the bottom
● If there is no maintenance space at the bottom, it is
recommended that the cabling space at the bottom
of the container be no less than 1.2 m.
● If there is maintenance space at the bottom, it is
recommended that the cabling space at the bottom
of the container be no less than 1.5 m.
2 Cable ● The bending radius of the cables is not less than 15
times the cable diameter.
● The voltage drop of the farthest loop does not
exceed 5%.
● The sensitivity, voltage level, and thermal stability of
the cables meet the local design
specications.
