Ballenden & Robb Consulting Engineers
High Voltage Substations & Power Transmissions
As Consulting Engineers to Local Authorities over many decades, Ballenden & Robb has the experience and expertise to provide a cost effective and technically sound solution to your high voltage network requirements.

We will provide any or all of the professional services you may require to design and implement new high voltage (up to 132kV) networks or upgrade or extend existing networks.
 
Substations
Our fields of expertise include all aspects normally associated with substation design. This could include indoor and outdoor switching, protection, control and metering equipment; Power Transformers and ancillary voltage regulation, control and protection equipment; SCADA systems; Load control equipment; Power Factor control equipment; Security systems; and all associated civil works.

High Voltage Networks
In the early stages of the development of the electrical networks in many towns and cities in Southern Africa, we introduced and implemented the modular triangle HV distribution model. It has been a very successful cost effective and flexible method of network design. It provides a master plan for the development of the MV and HV networks as the load on the network increases. A detailed discussion document on this concept is available on request.
