Advantages of Single Column Substation
24/05/2023
Single-column substation is a new type of substation with many outstanding advantages compared to previous types of traditional substations. Let's find out the specific advantages of a single-column substation through the article below.
1. What is a substation?
A substation (transformer) is a static electromagnetic device operating on the principle of electromagnetic induction, capable of changing voltage but keeping the frequency of the alternating current system unchanged.

Depending on the task and design, there are many different types of substations on the market, including:
– Indoor substations include closed stations; complete station form and gis station form.
– Outdoor substations (suitable for intermediate stations with large capacity) including hanging stations; truss station form; base station form; form of assembly station; low-voltage station type single-body steel pole, also known as sitting station. Among them, the single-column substation belongs to the low-voltage substation with single-body steel poles.
1 column substation – The perfect choice for urban environments
At present, when the economy is growing, urban areas and commercial centers are springing up more and more. However, with the current rapid urbanization, the supply of electricity to residential areas by traditional types of substations is facing many limitations, such as the traditional hanging station type, which saves money. land, but it loses the city's beauty, in the long run, it is not recommended to install it in urban areas and megacities.
At present, when the economy is growing, urban areas and commercial centers are springing up more and more.

To overcome this problem as well as ensure the demand for electricity in big cities, manufacturers have launched a new type of substation to the market, a 1-column substation. Compared with traditional substations and kiosks, 1-column substations both save investment costs and save land area costs while ensuring aesthetics and providing enough power for demand. demand of the people.
This new type of substation is a substation with a transformer installed on a single pole of centrifugal concrete or single-body steel pole. Single-body steel poles are constructed of galvanized steel, including transformer pedestal, pole body and pole base. Other parts are made from zinc coated steel with a thickness of 2mm and coated with an insulating paint.
Compared with traditional types of substations such as assembly stations, hanging stations, room stations, etc., the new single-frame substation only occupies a very small area, has high aesthetics, so it is suitable for installation. for urban areas. Also for this reason, 1-column substations are often installed outdoors in public places with small spaces and high population density such as parks, sidewalks, subways, airports, hospitals, etc. high-rise buildings, commercial centers, etc. In addition, the equipment is also used in manufacturing plants and industrial parks. It is known that single-column substations are being widely used in power transmission and distribution networks from 6kV to 35kV with transformer capacity up to 630kVA.
