Electricity distribution networks take high voltage electricity from the national grid and distribute it at lower voltages to homes and businesses.

Delta designs, builds, repairs, tests and maintains electricity distribution networks and heavy electrical equipment including substations, switchgear, transformers and much more.

And because we maintain one of the country’s largest networks, Aurora Energy, we have the first-hand experience and smart thinking to get the best from your electricity infrastructure assets.

You can rely on us to provide a full range of distribution-related services including design, civil construction, fibre-optic communications, earthing, testing and condition monitoring. Hard-to-get parts can be manufactured in Delta’s well-equipped workshop by our skilled technicians.

Whether you are looking for a turn-key solution or upgrading existing infrastructure, Delta has the specialist technical expertise and technology for the job.

We improve network performance for our customers by applying smarter thinking and the right technology.

Our expertise in cable technologies achieves high reliability on the networks we maintain. We’re at the leading edge in live working techniques, reducing system down-time when distribution networks are being maintained.

Delta’s advanced cable systems provide real-time monitoring throughout the entire cable installation, from manufacture to delivery, installation and livening.

We are an industry specialist in urgent on- and off-line fault finding and repair. Using state-of-the-art equipment, every aspect of the job complies with relevant regulations, standards, codes, and industry best practice.

In an emergency, our people are on the spot where you need them, reducing response times and supply interruptions.
