Xiangsi Lake Campus, Nanning Vocational and Technical UniversityEngineering of the Comprehensive Training Building for Industry - Education Integration (EPC)
The construction project of the integrated training building for industry - education integration in the new Xiangsi Lake campus of Nanning Vocational and Technical University requires the construction of supporting facilities.10kV power distribution facilities.
Core requirements of the project:
− Urgent construction period: As stipulated in the contract,the installation of high - voltage equipment and cable testing should be completed within 15 days;
− Equipment configuration: TwoZBW - 12 intelligent prefabricated substations + one outdoor switchgear cabinet;
− Environmental conditions: Nanning area has a subtropical climate, and the daily average humidity≤95%.
Applied products
Outdoor switchgear cabinets, prefabricated substations
Siwu Solution
Customer Value
1. Equipment selection
Trinity design:Integrated high-voltage cabinet (optional vacuum circuit breaker), transformer (S11 oil-immersed type), low-voltage cabinet (intelligent circuit breaker), reducing on-site assembly steps.
Environmental adaptability:
▶ Honeycomb double-layer composite shell (cold-rolled steel sheet substrate), protection level IP54;
▶ The high-voltage chamber is equipped with a temperature and humidity sensor (with the function expansion ability of "can be equipped with a distribution network automation terminal" according to the instruction manual).
Expansion compatibility:Reserved slot for distribution network automation terminal (FTU), supporting future upgrades.
Space intensification:The outdoor deployment of box-type substations eliminates the need for the construction of independent power distribution rooms.
Enhancement of intrinsic safety:
− The touchable cable heads in the switchgear eliminate the risk of electric shock;
− The five-prevention interlock of the KYN28 cabinet body prevents misoperation.
Optimization of operation and maintenance efficiency:
− Remote monitoring of the box - transformer status reduces on - site inspections;
− The handcart structure of the switchgear shortens the equipment maintenance time.
Sustainable expansion:The multi - circuit design of the switchgear station reserves the capacity for load expansion.
2. Optimization of the delivery process
Factory pre - installation and debugging:The internal wiring of the box - type substation is completed before leaving the factory to reduce on - site working hours;
Parallel construction:The equipment foundation and cable laying are advanced simultaneously.
1. The construction period is extremely short
The construction cycle of a conventional substation usually takes1 - 2 months, but the teaching schedule requires delivery within 15 days.
2. Space is limited
The equipment is placed outdoors, so outdoor compact equipment is required;
3. Environmental challenges
High - humidity environments can easily cause condensation on electrical equipment and a decrease in insulation.
