Electrical houses (ehouses)

Ehouse substations are better

TGOOD prefabricates ehouses ready for switchgear and other power equipment to be installed quickly. Construction, commissioning, testing and installation time is saved, while the scale of our manufacturing facilities keeps production costs down.

TGOOD’s ehouses allow the speedy deployment of compact, modular metal-clad switchgear, or outdoor GIS. Much of the HV and MV switchgear, and other electrical components, is pre-manufactured to drastically reduce project times. As a world leader in ehouse technology, TGOOD delivers thousands of units annually to meet the demands of customers and projects around the globe.

Why ehouse switchroom substations are better than bricks and mortar electrical buildings

In recent years, the construction industry has seen a significant shift towards prefabricated structures, including ehouses, kiosks and modular substations. These pre-engineered buildings offer several advantages over traditional concrete structures, making them a popular choice among project managers and engineering, procurement and construction companies (EPCs).

What does prefabricated mean?

Although an ehouse or electrical kiosk will be customised for each project, there are certain features many energy projects share. As such, TGOOD’s factories can prefabricate (manufacture in bulk) a range of different products, ready for final fit-out. This provides economies of scale and speed of delivery, while maintaining exceptional quality in the electrical building.

What is the difference between a kiosk, an ehouse and a modular substation?

The words ‘ehouse’ and ‘kiosk’ are both about metal-clad switchgear substations, however, a turnkey solution that involves a large switchroom building is more likely to be called an ehouse. A smaller room that houses six ring main units, for example, would be called a substation kiosk.

Ehouses are electrical houses used to house electrical equipment, such as switchgear, transformers, circuit breakers, LV panels and other control and protection systems. They are designed to provide a safe and secure environment for the electrical equipment, protecting it from the elements and ensuring safe and efficient operation.

TGOOD’s ehouses can be customised to meet the specific requirements of each project and are constructed using steel. Additional features TGOOD offers include heating, venting and air conditioning (HVAC) systems and fire suppression systems.

TGOOD’s ehouses are known for their robust design and speed of delivery, making them suitable for various applications, including at renewable energy plants in remote locations.

Modular substations are similar to ehouses in that they also house electrical equipment. However, they are typically larger and more complex, often including more than one building or module. The TGOOD 145kV urban substation shown right, for example, takes up only 416m2 as it has some modules stacked on top of others.

Modular prefabricated substations are designed to be installed in a variety of locations, including outdoor environments, and are often used in industrial and utility applications. TGOOD’s prefabricated substations are engineered for rapid deployment and high reliability, ensuring minimal downtime and maximum efficiency.

Prefabricated ehouse substations vs concrete

Prefabricated ehouse substations offer several advantages over traditional concrete structures:

Time and cost savings: Because ehouses, kiosks and modular substations are pre-engineered and built in a controlled environment, it significantly reduces on-site construction time and costs for the end user. TGOOD’s solutions are designed for quick installation, often taking just a few weeks to depart the factory compared to the several months required for traditional concrete structures.
Ease of installation: The installation process for prefabricated substations is straightforward since the structures are pre-built. This reduces the complexity and potential issues associated with on-site construction. TGOOD’s modular designs further simplify the installation process, ensuring seamless integration with existing infrastructure.
Cost-effectiveness: The initial costs of an e-house can be lower than those of a traditional concrete structure. The reduced installation time and labour costs contribute to overall savings. TGOOD’s prefabricated solutions are designed to be cost-effective, providing high-quality performance at a competitive price.
Quality and reliability: Prefabricated structures are built in a controlled factory environment, ensuring consistent quality and adherence to stringent standards. The TGOOD factories are accredited with ISO 9001, ISO 45001 and ISO 14001.

Advantages of prefabricated substations

Flexible design: TGOOD’s prefabricated substations can be customised to meet specific project requirements, offering flexibility in design and functionality.
Reduced installation time: The pre-engineered nature of these structures allows for rapid installation, minimising project delays.
Minimal maintenance: Prefabricated ehouses and require less maintenance compared to traditional concrete buildings, reducing long-term operational costs.
Improved quality: Built in a controlled environment, these structures ensure high-quality construction and performance.
Cost-effective: Lower initial costs and reduced installation time contribute to overall cost savings.
Environmentally friendly: TGOOD’s solutions are designed to minimise environmental impact, with reduced waste and a lower carbon footprint.

Disadvantages of concrete substations

Time-consuming construction: Concrete substation construction is a lengthy process, leading to potential cost overruns and project delays.
High cost: The labour, materials, and equipment required for concrete electrical buildings makes them more expensive than prefabricated alternatives.
Difficult maintenance: Concrete structures require regular maintenance to prevent corrosion and other issues, increasing long-term costs.

In summary, ehouse substations offer numerous advantages over traditional concrete electrical buildings, including cost savings, reduced installation time, and improved quality. TGOOD’s innovative ehouses and kiosks provide reliable, efficient, and environmentally friendly solutions for modern substation construction needs.
