Project challenges

In the limited-occupied industrial parks, the boundaries of the existing production networks and plants, the construction, installation of equipment, electrical access, fire-fighting connection and netting are completed, while minimizing the impact on existing production.

1
Limited site area: The available space is small and only about 38m x 22m.
2
Production continuity: Production continued during the construction, with a phased controlled switch.
3
Electrical capacity: Connection points are restricted and access is controlled by 1.25 MW.
4
Noise control: ≤ 65 dB(A)@1m.
5
Fire escape: 4m Fire access and equipment clearances.

Ten cabinets arranged in two blocks. (total energy 2.61 MWh)

Area A (5 cabinets) 01 02 03 04 05 PCS Box Transformer / Power Distribution Fire cabinet. Area B (5 cabinets) 01 02 03 04 05 PCS Box Transformer / Power Distribution Fire cabinet. Fire Access 4.0 m 38.0m 22.0m Liquid-cooled Battery Cabinet(261kWh) PCS Box (1.25 MW) Transformer / Switchgear Fire-fighting facilities
