I. Project Background

The Gaoshan Operation Area of Nanning Port Liujing Port is an important component at the starting point of the Pinglu Canal, located in a core position of the multimodal transport hub for the New Western Land-Sea Corridor. Constructed leveraging the mountainous terrain, this operation area primarily handles the loading, unloading, storage, and transfer of bulk cargo, placing specific demands on the environmental adaptability, continuous operation capability, and intelligent operation and maintenance level of the power supply system. The project employs our company's high-protection power distribution solution specifically customized for port and high-mountain environments.

II. Customer Pain Points

After the opening of the Pinglu Canal, cargo throughput will increase significantly; the existing power distribution capacity is insufficient and cannot support the new large-scale loading/unloading equipment and ancillary loads such as cold chain and storage.

The port operating environment is humid with strong salt spray corrosion; electrical equipment requires high protection and corrosion resistance capabilities.

The construction of the Pinglu Canal Economic Belt requires intelligent port operation; traditional power distribution systems cannot achieve remote monitoring, energy efficiency management, or rapid fault diagnosis.

Multimodal transport operations require 7x24 uninterrupted power supply; the current system lacks sufficient power supply reliability and redundancy, posing a risk of operational interruption.

The expansion of berths in the Gaoshan Operation Area requires the power distribution system to have modular expansion capability.

III. Proposed Solution

Selection of KYN28-12 withdrawable metal-clad switchgear as the core for high-voltage incoming lines, featuring high breaking capacity and strong disturbance resistance, ensuring grid stability under the load growth brought by the Pinglu Canal.

SWGCS-type low-voltage withdrawable switchgear adopts a modular design, supporting flexible capacity expansion to meet the future power supply needs of new equipment in the port, such as yard cranes in container yards and electric front cranes.

SWXL-21 power distribution cabinets, with enhanced protection treatment for the port's humid, salt-spray environment, are used for power distribution at the quayside and yards.

IV. Customer Value

High-standard power distribution facilities effectively guarantee the port's high-load, continuous operation demands after the Pinglu Canal becomes operational, supporting throughput growth.

The equipment's high-protection design and intelligent O&M functions significantly reduce failure rates in the salt spray and humid environment, decreasing maintenance frequency and costs.

The system possesses scalability and intelligent interfaces, meeting the long-term development needs of Liujing Port as a hub for the New Western Land-Sea Corridor.

Enhances power supply reliability and power quality, providing stable power for port automation equipment.

Strengthens the port's green energy capability, laying the foundation for subsequent participation in green electricity trading and carbon emission reduction demonstration projects.
