Modular Substations

Modular Substations
Customised footprint design for switchroom, switchyard and transformer installations.
The Ampcontrol modular substation concept is a proven and viable alternative to building concrete, brick and mortar substations. The modular design for applications such as zone substations and radial substations is shipped as a packaged system ready for assembly on site.
The substation can be designed, manufactured, fully assembled, wired and operationally tested in our workshop. The advantages and benefits of this type of installation offer significant savings.
Site works are minimised and delays due to inclement weather and the integration of site services can be greatly reduced.
Zone substation manufacture and installation
Stage 1
Factory assembly and testing
•
•
•
•
Incoming high and low level busbar structures assembled
Modular switchroom manufactured and fitted out
Rotary isolators, CT’s and VT’s positioned onto modular switchroom
Complete installation tested prior to disassembly and shipment
Occupational health and safety risks are minimised along with environmental risks, and labour demands on site are kept to a minimum.
The low profile design is more readily accepted by the community, making the modular substation an ideal solution for fast tracked projects.

Stage 2
Civil works
• Concrete piers installed for switchroom/ incomer modules
Retaining walls constructed and site levelled
Feeder cable conduits laid
Earth grid installation
Top surface completed
Modular base structures for incoming supply installed
Advantages over on-site construction:
•
•
•
•
•
•
•
Faster response to network augmentation requirements
Greater flexibility in the network
Workshop assembly and testing of major components
Labour demands on-site minimised
Can be relocated to another site or easily extended
Minimal environmental impact
Training and familiarisation during workshop testing stages
Stage 3
Equipment installation
•
•
•
Transformer and cooling unit placed in position
Modular switchroom positioned on piers
Pre-assembled rotary isolators positioned onto switchroom overhead frame
Total turnkey projects:
•
•
•
•
Project management
Engineering design
System integration via SCADA
Installation, commissioning and maintenance
Stage 4
Incoming switchgear and cabling installation
•
•
•
•
•
Incoming equipment assembled onto base
Factory manufactured individual overhead cabes installed
Earth grid tails connected to incoming modules
Feeder cabling terminated
Testing and commissioning

Modular Substations

Flexible design
Utilisation of the modular design allows for additional units to be added as demand increases.
Single incomer, single transformer.
