Low Voltage Switchboards



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 to produce sodium dichromate, which is mainly further processed into chrome tanning materials for the global leather industry.

The plant is the 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.

RENEWABLE ENERGY - Khi and Kaxu Solar One Project

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 demineralised water that is used for the steam in the generator turbines.


The following scope of work was completed by Low Voltage Switchboards:

  • Detailed EC&I Design
  • Manufacturing and supply of Redundant Control
  • System for fully automated water plants.
  • Complete E&CI Installation
  • Hot & Cold Commissioning

  • EC&I 3D Cable Rack Modelling

POWER PLANTS - Kuvaninga Power Plant Project

Low Voltage Switchboards was appointed by Cross EPC 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 consists of 10-off (GE Jenbacher) gas-engine driven generators, each of 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 scope of work was completed by Low Voltage Switchboards (Pty) Ltd:

  •  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, lighting and small power.
  • Specifications for all MV and LV equipment; these include:             – Specifications for 55MVA transformer; Auxiliary Transformers; MV Switchgear; NECRT; Surge Arrestors; Motor Control Centers; UPS’s; Lighting, Earthing and cables
  • Specifications for installation of equipment.
  • Protection Philosophy, Protection setting 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.

TURNKEY - St. Helena Airport Project
