Client: Kenya Ports Authority (via EPC Contractor from China Communications Construction Co.)
Application: Reliable electricity distribution for cranes, reefer container yards, and terminal operations
Project Overview:
QZ Switchgear provided a complete MV/LV distribution system for the Mombasa Container Terminal expansion, the largest port in East Africa. The supplied equipment supports heavy-duty port cranes (STS, RTG, RMG), refrigerated container stacks, lighting systems, and port operation buildings. This ensures stable and efficient port operations, critical for Kenya’s import-export trade.
Technical Highlights:
Medium Voltage Side
33/11kV transformers feeding into KYN28-12 switchgear panels
Feeder panels dedicated to STS cranes, reefer yards, and terminal substations
ZW32-12 recloser breakers installed along overhead feeders for automatic fault isolation
Low Voltage Side
Prefabricated container substations distributed across the port yard for localized supply
GCS LV panels configured for reefer container stacks, ensuring stable 24/7 refrigeration supply
Reactive compensation panels with automatic controllers to improve power factor >0.95
Shore Power Supply
Dedicated shore connection cabinets to supply electricity to berthed vessels
Eliminates need for auxiliary ship engines, reducing carbon emissions and noise
Client Benefits:
One-stop turnkey solution simplified procurement and engineering review
Port reliability improved: Dual supply feeders with auto-transfer ensured uninterrupted crane operation
Energy efficiency: Power factor correction reduced energy losses and avoided utility penalties
Sustainability: Shore power connection aligned with IMO regulations on port emissions
