Advantages Of Prefabricated Substation

Faster installation and deployment: Prefabricated substations offer a significant advantage when it comes to installation speed. Unlike traditional substations, which require extensive on-site construction, modular substations arrive pre-assembled and ready for deployment.

Cost savings in construction and maintenance: Prefabricated substations deliver lower installation costs and long-term savings. By manufacturing components offsite, you avoid the high labor costs associated with traditional construction.

Enhanced safety and quality assurance: Safety is a top priority in industrial applications, and prefabricated substations are designed to meet the highest standards.

Flexibility and scalability for industrial growth: Prefabricated substations provide unmatched flexibility, making them ideal for industries with evolving power needs. Their modular design allows you to scale your power distribution system as your operations grow.

Reduced environmental impact: Prefabricated substations offer significant environmental advantages over traditional ones. Their factory-built, modular design occupies a smaller footprint, reducing the amount of land required for installation.

Applications of Prefabricated Substation

Prefab substations are suitable for use in industrial, commercial and residential locations. They are suitable for factories, mines, construction zones and more. Rural neighborhoods and businesses may also find prefab substations suit their needs better than conventional substations.

Construction sites may opt for a prefabricated station as they can easily move between sites. Some industries with a substation may purchase a prefabricated system as a backup. Because prefabricated stations are so easy to take down and reassemble, they are often used as backup power when a conventional substation is undergoing maintenance and repairs.

Types of Prefabricated Substations

European prefabricated substation

In terms of use, this is probably the most widely used type of prefabricated substation. Their modular design makes it very convenient to manufacture and install them. The equipment is completely reserved in the factory, and the appearance style is more diversified, which can greatly meet all the needs of customers.

American prefabricated substation

This is also a kind of box type substation. It has been introduced into China successively with the European box type substation. The American box type substation is different from the European box type substation in shape and generally smaller than the European box type substation. The American box type substation is a substation equipment that combines transformers, high-voltage load switches, fuses, etc.

Buried substation

That is, the prefabricated substation buried underground. According to the needs, it can be divided into semi buried type and fully buried type. The former is generally used for power supply of municipal construction and landscape architecture. Therefore, it is also called landscape box type substation.

Miniaturized box type substation

This is actually based on the specific products in the alternative box type substation design scheme. It belongs to the scope of European box type transformer substation, but it is quite special. They occupy less land, have different internal structures, are more personalized in appearance, and have a high degree of intelligent control. They are one of the representative products of modern and future prefabricated substations.

Components of Prefabricated Substation

A prefabricated container substation usually consists of three main components: enclosure, transformer and switchgear. Enclosures are substation enclosures designed to protect components from environmental hazards such as rain, wind and dust.

A transformer is a component that converts incoming high voltage electricity to a lower voltage level suitable for power distribution. It is usually located inside the enclosure and can be customized to meet specific power requirements.

Switchgear is the component that controls the distribution of electricity through a substation. It includes circuit breakers, switches, and other protective devices that ensure safe and reliable power distribution.

Other special requirements can be negotiated with the manufacturer.

Usage Environment of Prefabricated Substation

Ambient air temperature is no more than 45℃ at the highest and -45℃ at the lowest. Altitude is no more than 1000m above sea level. If special customized transformers and low-voltage components are used, the altitude can reach 4000m above sea level. Vertical inclination is no more than 5°, and there is no severe vibration and impact.

Air humidity is no more than 90% (+25℃). No conductive dust, no explosion hazard, no gas that corrodes metal and electrical components. Outdoor wind speed is no more than 35m/s. Beyond the above normal use environment conditions, customers can customize solutions with our company.

FAQ

Q: What is a prefabricated substation?

A: Prefabricated substations typically consist of three main components: high-voltage switchgear, transformers, and low-voltage power distribution equipment. They are broadly categorized into two types: pad mounted transformer and compact transformer.

Q: What is a package substation?

A: A package substation usually consists of an RMU (Ring Main Unit) or a HV switch (High-Voltage switch), cast resin transformer, transformer housing, high-power copper or aluminium busbar which is directly connected to a main LV Switchboard.

Q: What is a prefabricated system?

A: Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located.

Q: What does prefabricated mean in engineering?

A: Prefabrication involves the production of building components, modules, or entire structures, which are then transported to the construction location for final assembly. This approach offers numerous advantages, including cost-effectiveness, reduced construction time, and improved quality control.

Q: What is the difference between a station and a substation?

A: The main difference we find between a transformer station and an electrical substation is the magnitude of the installations. While transformer stations are linked to high/medium-voltage transmission systems, electrical substations are designed to support and transform lower voltages.

Q: What is a pocket substation?

A: Pocket substation or mini substations are portable and self-contained. They are typically enclosed with lockable doors in a steel case and sometimes fitted with rollers. The pocket substation consists of the fused transformer connected with circuit breakers and secondary bus bars.
