How To Buy Power Transformers In Australia | Daelim Belefic

Power Transformer is necessary for modern human society, to transfer the high voltage power from power plant, to low voltage power for industry, public utilities, data centers, etc... 

We were talking about power transformer business in USA, Canada, Latin American markets before, today we are going to learn more about another market of Daelim Belefic: Australia market. 

Daelim Belefic can design and produce power transformer based on multiple standards, from ANSI/IEEE, CSA, to IEC, GOST, also include AS/NZS standards for electrical transformers Australia.

1.Why We Need Power Transformer

If we call the world economy as a human body, the electric power will be the muscle of this body. Electric power up human society and move forward since the Second Industrial Revolution. Even now the new energy technology is growing up, it still needs to change to electric power to use for human society.

Under this background, power transformer, also called an electrical transformer, becomes the core of the whole power industry, even the core of the whole human economy. 

The electric power from the power plant has a very high voltage, from 300kV to 1000kV. This kind of high voltage can not be directly used by our electrical equipment. The electric power we use is low voltage such as 220V, 415/240V, 230V, etc...

So how do we transfer the high voltage from the power plant to the low voltage for our electrical equipment?

The power system is divided into three major components: generation, transmission, and distribution. Electric power comes out of the power plant, will transfer to higher voltage into the transmission system first, then move to step-down substations, transfer to the low voltage by step-down transformers. To power up our electrical equipments. 

In the power distribution system, there are substation transformers and distribution transformers. Distribution transformers include oil immersed transformers and dry type transformers. Daelim Belefic can produce both of these two types for the international market.                                                         

2.Power Industry In Australia

Australia's electricity grid comprises several independent systems: the Eastern Interconnection linking Queensland, New South Wales, Victoria, Tasmania, and South Australia, alongside separate grids in Western Australia and the Northern Territory. As of January 2020, the country has a total installed power capacity of approximately 48GW, with coal historically dominating but a growing share of renewable energy, including residential photovoltaics shaping demand patterns. The National Electricity Market (NEM) and the Wholesale Electricity Market (WEM) are key frameworks governing electricity supply and transactions across regions.

                                                                                                  
3.Power Transformer Business In Australia

In the power distribution system, we have 2 type of transformer products. Substation transformer and distribution transformer. Let’s have a deeper look at the transformer industry in Australia. 

Substation Transformer: 

Transformers of the substation type are commonly used in power substations, factories, data centers, mining farms, etc. They have a large electricity demand, so they need transformers with large capacities, large sizes, and high voltages. 

Substation transformer, also known as substation transformer for short, is a total step-down transformer used primarily to transmit and transform power in a unit or substation. Substation transformer is the core part of a substation. Transformers are essential equipment of the electric locomotive traction power supply system, and they are also essential equipment to assure traction power supply system stability and safety.

Generally, main transformers have large capacities and must be highly reliable. Even though the substation transformer is not likely to fail often, when it does, it will cause substantial losses. It may cause equipment failure if it is light; if it is serious, it will cause a fire and threaten transportation safety. Therefore, it is essential to analyze the fault causes of the transformer and to take the appropriate preventive measures.

Substation transformer will be designed based on AS/NZS standard, for Australia and New Zealand use. 

For high voltage substation transformer, Daelim Belefic can produce up to 235kV, 200MVA.

Distribution Transformer: 

Distribution Transformer is a very important part of the electric distribution system. 

Transformers used in distribution systems are static electrical equipment that converts specified voltages and currents into other or several different voltages and currents with the same frequency. As an alternating current is applied to the primary winding, an alternating magnetic flux is generated and an alternating electromotive force is produced in the secondary winding due to the magnetic permeability of the iron core. The secondary induced electromotive force is proportional to the number of turns of the primary and secondary windings. Its primary function is to transmit electrical energy since its rated capacity is its most important parameter. Generally, the rated capacity is a customary way to measure power, which is the size of the transmitted electrical energy, expressed in kVA or MVA. With the rated voltage applied to the transformer, the rated current is determined that does not exceed the temperature rise limit under specified conditions. The amorphous alloy iron core distribution transformer is the most energy-efficient power transformer, and one of its biggest advantages is its low no-load loss value. Whether the no-load loss value can be finally guaranteed is the core issue to be considered in the entire design process. When arranging the product structure, in addition to considering that the amorphous alloy core itself is not affected by external force, the characteristic parameters of the amorphous alloy must be selected accurately and reasonably during the calculation.

In the Australia market, Daelim has different types of distribution transformers:

Mini substation transformer: Mini substations are prefabricated electrical equipment units that include medium voltage and medium voltage switchgear, power and distribution transformers, low voltage switchboards, connection busbars, and other accessories.
