Concrete enclosures for transformer and distribution substations

Modern transformer and distribution substations must have concrete enclosures. These buildings offer vital electrical equipment a strong, long-lasting, and secure home. Substations, the backbone of our electrical system, are essential to the effective management and distribution of electricity. Concrete is used for these enclosures because it provides protection from weather and physical damage in addition to guaranteeing structural integrity.

The exceptional fire resistance of concrete enclosures is one of their main advantages. Concrete aids in damage containment and reduces the possibility of a fire or electrical malfunction spreading to neighboring areas. Both the safety of the public and the continuous operation of the electrical grid depend on this containment. Furthermore, concrete is the perfect material for withstanding impacts from both human activity and natural occurrences like storms due to its inherent strength and durability.

The ability of concrete enclosures to reduce noise is another important benefit. When in operation, transformer and distribution substations can produce a lot of noise, which can be problematic in residential or urban areas. The surrounding environment is less affected by these noises thanks to the absorption and damping properties of concrete walls. This benefit satisfies noise-level regulations while also improving the general quality of life for those who live nearby.

To sum up, concrete enclosures provide a strong way to safeguard important electrical infrastructure for transformer and distribution substations. They are an excellent option for guaranteeing the secure and effective functioning of power systems due to their strength, fire resistance, and noise-reducing characteristics. Since many aspects of our daily lives still depend on electricity, concrete is still essential to protecting our energy networks.

For transformer and distribution substations, concrete enclosures offer crucial security and safety, guaranteeing the dependable operation of electrical equipment. These buildings provide security, resilience to fire, and durability while protecting delicate parts from the elements, vandalism, and other possible risks. Concrete can be used to increase the longevity and efficiency of substations, which are essential for ensuring that our communities have a steady supply of electricity.

Purpose

Substations are used to receive, distribute, and convert current through concrete enclosures.

There are many uses for these structures on electrical networks in buildings. These could include manufacturing facilities, urban networks in specific locations, suburban areas with differing degrees of separation from the city, and industrial enterprises.

Concrete structures of this type are used everywhere and enable you to efficiently carry out assigned tasks because of their mobility and capacity to quickly and easily deliver package transformer substations (BKTP) to any point.

Types

There are various versions of concrete enclosures available. The decision is based on the facility’s operating parameters, the customer’s personal preferences, and the features of the connection. While many companies can create a reinforced concrete structure tailored to a specific project, there are standard projects available as well.

Features

The guidelines and all technological stages must be closely followed when creating concrete substation enclosures because this facility is subject to more stringent safety regulations.

• Absolute flexibility of the nomenclature
• The need to implement modern mechanisms that demonstrate an increased level of safety
• Ease and speed of installation work
• Requirement for a small building area
• Harmonious combination of the appearance of the building with the surrounding architecture

Transformer substation concrete housings have a very straightforward design: they are just concrete boxes made for particular projects. The body is resistant to moisture, fire, frost, and UV radiation because high-quality concrete was used in its production.

There is a foundation and the major above-ground portion of the body inside. All structural components are composed of materials that are fire-resistant and do not catch fire, even when they come into contact with open flames. The enclosures are painted any color, in any combination, to make them look as close to the surrounding architecture’s objects as possible.

Specialized transportation is used to deliver concrete substation buildings to the designated location, where they are installed. After that, all cables are installed and connected, and grounding is established.

• Quick, simple and easy installation
• High quality of execution – thick strong walls, reliable roof, sealed foundation (does not allow oil to penetrate into the ground) guarantee the reliability and durability of the structure
• Ability to perform any finishing of the drain and walls
• Excellent heat and humidity characteristics inside the building

Substation components

Concrete sections of substation enclosures can be one, two, or three in number. Concrete semi-basements are typically included in the design kit; an electric cable is run through them via the floor opening and the foundation. The building’s floor is composed of a load-bearing plate that is 10 centimeters thick and weighs 18 tons; the walls themselves should be at least 80 to 100 millimeters thick. With the equipment, the building’s total weight has already been considered.

Metal is used to make window grilles, doors, and gates. Current building codes and regulations require the installation of a ventilation system.

Transformers, instruments for accounting and measuring electricity, and low- and high-voltage electrical installations are typical substation components.

A substation’s price is determined by the structural elements’ design features as well as a number of details, including the input method, foundation, ventilation system, and type of shell. Power and the quantity of transformers, meters, grounding, circuits, lines, and disconnectors all have an impact on the cost.

Concrete housings for substations

Concrete transformer housings are available from modern manufacturers and are used in public, industrial, and residential buildings. Concrete ensures that the structure is protected from all external factors (such as weather, vandals, mechanical loads, etc.), which promotes long-term safety and durability.

Concrete also makes it possible to build lightweight, compact enclosures that don’t need a large, impressive space at the facility. Enclosures can be set up for either short-term or long-term use.

It should not be too difficult to find or design what you need because Moscow and the surrounding areas offer a sizable selection of designs from numerous manufacturers.

The above-ground structure, which makes up the lower portion of the block, is intended for outdoor installation. Enclosures are made in the necessary sizes and configurations, following the technical specifications that the customer provides. The enclosure has textured paint on both the inside and outside.

The enclosure’s above-ground portion is a sturdy reinforced concrete box designed to house electrical equipment. Typically, the box is made of a monolithic, straightforward rectangular or square shape with floor openings that are intended to be lowered into an underground large-volume block.

There, the KRUVN and RUNN cables are installed, and the power transformer’s oil is drained. Additionally, there are metal parts embedded in the floor that are used to fasten the equipment inside the above-ground unit, as well as guides for the transformer.

The subterranean pit is constructed as a four-wall monolithic base with a floor that is recessed into the earth. In addition to serving as the housing’s foundation, this area is used to build a concrete platform on which gaskets, cable lines, section jumpers, and other system components are installed. They can be accessed through a detachable ladder. It is feasible to install a metal oil receiver with the required capacity in order to receive oil.

Working conditions

It is worthwhile to research the established guidelines and regulations in order to establish the best possible conditions for the transformer’s operation.

• The design of the housing must be made in accordance with regulations, state standards, marking U1.
• The product is installed outdoors in regions with a moderate climate.
• Ambient temperature: not higher than +45 degrees Celsius and not lower than -47 degrees.
• Ice/wind level – first to fourth.
• The installation site is located no more than 1 kilometer above sea level.
• The BKTPS can be installed in a fire and explosion hazard zone, but with the absence of chemical gases, vapors.
• Seismic resistance level of the area – up to 7 points on the Richter scale.

In conclusion, concrete enclosures provide a sturdy and dependable way to house distribution and transformer substations. They are a great option for safeguarding important electrical equipment because of their robustness and resilience to environmental conditions. These enclosures increase the overall safety of the installation by protecting the equipment from fire as well as physical harm.

The potential of concrete enclosures to lower noise emissions is another significant benefit. This is especially crucial in residential or urban settings where noise pollution may be an issue. Concrete reduces the impact of operational noises, such as transformer hums, by absorbing and dampening sound, so providing a quieter environment for the residents nearby.

Furthermore, concrete’s adaptability makes it possible to customize it to fulfill particular functional and design specifications. Concrete enclosures can be customized to meet a variety of needs, whether it be for size, shape, or extra features like ventilation or access points. They are a favored option for substations in a variety of industries due to their adaptability, strength, and protective attributes.

In general, installing concrete enclosures for distribution and transformer substations is a wise choice that will pay off in the long run by increasing security, toughness, and reducing noise. Purchasing high-quality enclosures will be essential to maintaining the dependability and effectiveness of power distribution systems as infrastructure demands rise.
