The SKA-Low telescope project

The SKAO is an advanced Big Data facility in radio astronomy that brings together countries worldwide. Its goal is to build and use advanced radio telescopes to transform our understanding of the universe. With headquarters in the UK and telescopes in South Africa and Australia, SKAO will become a leading research infrastructure for radio astronomy. Global collaboration and innovation will provide scientific opportunities for the international astronomical community, making SKAO a key player in advancing knowledge about the universe for decades to come.

Construction of telescopes on site began in December 2022 in Australia and South Africa. The SKA-Low telescope, on Wajarri Country in Western Australia, will comprise more than 131,000 two-metre-tall antennas detecting low frequency radio signals, and the SKA-Mid telescope, being built in the Karoo in South Africa, will comprise almost 200 dish-shaped antennas picking up higher frequency radio signals.

The SKA telescopes will be built, maintained and operated on behalf of the global community, and will look back in time billions of years to solve many mysteries of the Universe. The project includes the construction of two powerful supercomputers and is expected to be completed in 2028, with a total cost estimate of €1.3 billion.

Sustainability “Built to last”

The medium-voltage panels that will be installed in Australia are of the DF-2 type and are manufactured with a strong focus on sustainability. This product range is specifically designed to operate long-term and efficiently, which is crucial for a project of this size. The decision to partner with SGC highlights the SKAO project’s commitment to an environmentally friendly and future-proof approach.

One unique requirement of the SKA-Low telescope is for all installed electrical equipment to produce very low levels of electro-magnetic noise emissions. The advanced design and robust construction of the DF-2 range produces very low electrical partial discharge levels making them ideal for use within the SKA-Low telescope facility site. It can often get very hot in the outback, but our DF-2 switchgear can be exposed to high temperatures and withstand extreme weather conditions.

Longevity is an important feature for us. Our standard DF-2 line is produced according to the IEC 60932 §4 standard. This non-mandatory, additional requirement of the International Electrotechnical Commission (IEC) for standard material covers intensive climatic conditions according to method A level 2. This includes a cycle every 4 hours, where conditions vary between 30°C with 80% humidity and 50°C with 95% humidity. The total duration of this cycle is 9 days. Hence our well-known motto “built to last”.

Arc Killer for safety

Safety is paramount. The equipment will have an Arc Killer option, which not only protects the plant itself, but also ensures operator safety. Our Arc Killer is a device that prevents or stops electrical arcing. These sparks, which can occur when switching power, can cause fire and damage. The Arc Killer quickly detects and suppresses lightning within 48 milliseconds, which is 8x faster than the blink of an eye. Our electric arc reduces risks, protects electrical systems and thus contributes to a safe working environment, which is crucial for this project.

SGC and NHP: reliable partners for the SKAO project.

SGC is delighted to play a crucial role in the SKAO project. By providing reliable and sustainable energy, we support the scientific community in gaining insights that will further enhance our knowledge of the universe.

Solar photovoltaic power plant with SGC DF-2 equipment commissioned in Bithéa, Abéché, Chad

This is a nice reference project in the Sahel area where SGC has supplied several DF-2(+) types of high quality air insulated AIS switchgear.

The contract was won because of our good references for sustainable products in Chad.

Innovent, through its Chadian subsidiary, built the Abeche solar power plant. The construction site, which started in May 2019, currently consists of 3,600 solar panels, 40 trackers and 10 inverters of 100 kW each, for a capacity of 1 MW. Eventually, the park will consist of 21,600 solar panels for a total capacity of 5 MW. Innovent manages the park with its own staff on site.

The solar power plant consists of polycrystalline panels mounted on trackers, which follow the path of the sun from east to west and will thus increase production by 25% compared to a fixed system.

The energy situation in Chad is tense. According to the World Bank, only 8% of the population has access to electricity.

The objective of the solar park is to reduce the consumption of polluting diesel. This seems to have worked well since the park was commissioned at the end of last year.

The solar photovoltaic plant will allow SNE to cover the electricity needs of the city of Abeche with about 80,000 inhabitants.

We are very proud to contribute with our products to this renewable energy project.

Check out the case study from our reseller NHP

NHP was proud to assist in upgrading the Oxley Creek Sewage Treatment Plant in South East Queensland for flood resilience and optimising operations with a healthy and efficient electrical design.

The Solution: DF-2-air insulated switchgear module with built-in arc quenching system ‘Arc Killer’

The project included decommissioning the original high-voltage switchroom and the 11kV main switchboard for the site, and replacing it with a new main 11kV switchboard contained within a demountable building. The building was also raised 30cm above the 2011 peak flood line levels.

Within the switchroom, NHP specified the DF-2 air-insulated switchgear module with demountable vacuum circuit breakers and a remote operation functionality. Exclusive to NHP switchgear, the cubicles were specifically designed to minimise the consequences of an internal arc and forming a key component of this, is a built-in arc quenching system “arc killer”, which can extinguish an arc in less than 50ms.

“NHP were able to design, supply and install a solution for Queensland Urban Utilities that not only meets local requirements, but delivers an advanced technology which only NHP offers to the market.”

Medium Voltage Switchgear Project

For a substation of SNE in Chad, contractor Deba opted for SGC’s DF-2 program. All our products are built to last and meet the highest technical standards. The DF-2 line is specially designed to function properly in exceptional environmental conditions. For example, the metal-enclosed air-insulated medium voltage cubicles can withstand extreme heat. Ideal for the steppe climate of the Sahel region, where temperatures can rise to 50 degrees.

Not only for these reasons, Deba opted for the DF-2 medium voltage switchgear from SGC. But also for the modular concept where the combination of cubicles is unlimited. Very complex diagrams of distribution and transformer switchgear can be compiled through this extensive spectrum of possibilities.

For this project, a medium voltage substation was designed and assembled in collaboration with Deba and CUSTOMIZED to the needs of the end customer SNE (Société Nationale D‘Électricité)

Type of security cubicles?

The cubicles can be equipped with the most diverse and wide-ranging options. The customer chose cubicles of the type DF-D/EDN: protection cubicle with vacuum circuit breaker, block current transformers and equipped with a MICOM relay from General Electric at the request of the client, because they have experience with it. The relay will be programmed here by the end customer according to the selectivity study of the network in Moundou during the FAT study.

Why choose the container solution?

DF-2 medium voltage cubicles pre-tested, installed and wired in a container. A fast, cost-efficient and reliable medium voltage solution. This is the reference project and trendsetter for sustainable substations supported by FIT (Flanders Investment and Trade). We expect similar projects to be required for the expansion of the installed capacity in Chad. In fact, they have an acute shortage of generation capacity out there.
