EC-I

Low Voltage Switchboards was appointed by Ovivo Aqua SA as the EPC Electrical, Control and Instrumentation Contractor for the Water and Waste Water treatment plants on the KHI and KAXU Solar Plants in the Northern Cape of South Africa. The plants extract water from the Orange River and produce different stages of water quality for use on the Solar Plants, where the final stage is demineralized water that is used for the steam in the generator turbines.

The following socpe of work was completed by Low Voltage Switchboards:
- Detailed EC&I Design
- Manufacturing and supply of Redundant Control Systems for
  fully automated water plants
- Complete E&CI Installation
- Hot & Cold Commissioning
- Details as Built Drawings & Documentation
- EC&I 3D Cable Rack Modeling

Process & Chemical Plants

Process-Chem

Low Voltage Switchboards was responsible for the entire EC&I turnkey solution - design, supply, installation, commissioning and final handover.

Specialty chemicals company LANXESS commissioned a new CO2 concentration unit at its Newcastle production site in South Africa.

LANXESS operates a highly modern plant at the site for the production of sodium dichromate, which is mainly further processed into chrome tanning materials for the global leather industry.

The plant is the only only of its kind in South Africa.

The production technology requires a continuous supply of highly concentrated CO2, which was provided by the new unit.

Power Plants

Cross-PE

Low Voltage Switchboards was appointeed by Cross PE on behalf of Group Five as the EC&I design engineers for the Kuvaninga Power Plant located in the Chokwe (region), Mozambique. The Kuvaninga Power Station consits of 10-off (GE Jenbacher) gas-engine driven generators, each rating 11kV, 4.035MWe, 5.036MVA, 0.8pf, with an estimated maximum output, less station auxiliaries, of 38.5MWe. The generators will operate in parallel on the station main 11kV switchboard. The 55MVA transformer raises the station bus voltage to 110kV for connection to the Mozambique grid (EDM).

The following was completed by LVS:

    Medium Voltage Reticulation for all generators to the Main 55MVA evacuation transformer as well as auxiliary supplies.

    Low Voltage Reticulation for all the engine auxiliaries and lighting and small power

    Specifications for all MV and LV equipment. These included specification for 55MA transformer, Auxiliary Transformers, MV  Switchgear, NECRT, Surge Arrestors, Motor Contro Centres, UPS’s. Lighting, Earthing and Cables.

    Specifications for installation of equipment

    Protection Philosophy, Protection Settings calculations, ETAP Simulations and Switching procedures

    Control system design for all auxiliary equipment and interfacing with the engine control panels.

    Instrumentation specifications.

    Electrical, Control and Instrumentation 3D Cable Rack Modeling.

Mining & Minerals

Easily

Low Voltage Switchboardshas been supplying Motor Control Centres to the Mining & Minerals sector since our inception.

The modular design of the system means it is easily adaptable for any application and consequently has been supplied to many African and International mining sites.

The CUBIC system complies with all required international standards ensuring the highest level of safety and quality.
