Figure 5-4 Container foundation (recommended)

Recommended foundation cross-section area (Length × Width): 3113mm×2438mm.

According to the position and size of the cable inlets/outlets at the bottom of the container,
cables must thread through the bottom of the container. During the foundation construction,
reserve the trough for AC/DC cables and pre-bury the wire pipes.

The specifications and quantity of wire pipes should be determined by the models and
quantity of cables used.

Catch pits should be designed at the bottom of the foundation and drain pipes should be
provided.

In order to maintain the convenience, it is recommended to design the step ladder under the
manhole.

Pre-bury 50mm×5mm hot galvanized steel plates diagonally at the foundation as the
grounding units. The recommended depth is 0.8m. Weld one end of the hot galvanized steel
plates with the main grounding network of the power container and the other end with the
pre-buried steel plates. Make sure the welding is firm and reliable.

It is recommended to build steps at the front door of the container to facilitate entry of
personnel. Recommended step height: 150mm; depth: 300mm; width: 1200mm. The number
of steps should be determined by the actual situations on site.

The two ends of all pre-buried pipes must be sealed temporarily to prevent entry of foreign
objects so as to facilitate future wire implementation.

After electrical connections, cable outlet/inlet and gaps in-between should be sealed with
fireproof mud to prevent entry of rodents.

For other recommended sizes, please refer to the above figure and drawings.
