In the electricity industry, the switchboard is known as one of the vital components of energy distribution and control systems. Among the different components of the switchboard, the skeleton of the switchboard is particularly important because this metal structure plays the role of the backbone of the system and is responsible for the safe maintenance of electrical equipment and parts. The use of a standard skeleton and compliance with assembly technical points is one of the main parameters in increasing the safety, durability and efficiency of the electrical panel.
In Tehran, Behran Tablo Industrial Group, as one of the leading manufacturers and experts in the field of electrical panel design and construction, has been able to provide products with high industrial quality and full compliance with international standards by relying on CNC cutting technology, precise bending and electrostatic powder coating.
The nature and role of switchboard skeleton in electrical systems
The skeleton of the switchboard is a resistant metal structure that forms the body of the switchboard and all electrical components such as switches, fuses, rails, terminals and control circuits are installed inside it.
The presence of a strong skeleton not only keeps the order and safety of the equipment, but also prevents mechanical and thermal damage. In addition to high mechanical strength, a standard switchboard frame must be resistant to rust, moisture, dust, and heat to ensure system performance in any condition.
Features of standard switchboard skeleton
1. High mechanical strength
One of the most important features of the skeleton of the standard electrical panel is its high resistance to pressure, vibration and physical damage. In Behran Tablo Industrial Group, high quality thick steel sheets are used to increase strength. These sheets are cut with CNC machines and bent in a precise way to make the board without deviation and deformation.
2. Ergonomic design and easy access
The electrical panel should be designed in such a way that it is easy to access the internal parts during the installation or maintenance of the equipment. The ergonomic design of the skeleton of the electric panel in Behran Tabola helps to carry out the process of wiring, repairing and testing the equipment without possible damage.
3. Proper ventilation and air circulation
Industrial electrical panels may generate significant heat during operation. For this reason, the existence of ventilation valves and air flow paths in the skeleton of the electrical panel is very important. The design of the standard ventilation system reduces the internal temperature and increases the durability of the electrical equipment.
4. Resistance to moisture and corrosion
In the production process of Behran Tablo, after making the skeleton, the step of degreasing and electrostatic powder painting is done with high precision. In addition to its appearance, this coating prevents rusting and corrosion of metal in wet environments. Such a feature makes the skeleton of the switchboard more durable in the industrial environments of Tehran, factories and open spaces.
5. Compliance with international standards
A standard switchboard frame should be designed and manufactured according to IEC and ISO standards. Behran Tablo Industrial Group fully observes all the principles of mechanical safety, distance between insulators, suitable dimensions of equipment and structural specifications in the manufacture of its panels.
6. Strong connections and basic assembly
In the construction of the skeleton of the electrical panel, the assembly method of the parts is of particular importance. The use of screws, precise welding and stainless fasteners increases the mechanical durability of the panel. In Behran Tablo, assembly is done with precise tools and by experienced experts so that there is no slack or inconsistency in the structure.
One of the features of electrical panel skeleton production by Behran Tablo Industrial Group is the possibility of exclusive design based on customer needs and type of application. The dimensions, position of the doors, installation location of the equipment and even the color of the board can be changed and adjusted according to the project.
Raw materials used in the construction of the skeleton of the electrical panel
Choosing the right material from the design stage to production plays a vital role in the final quality of the electrical panel. In Behran Tablo Industrial Group, cold-rolled and galvanized steel sheet with standard thickness is used. In addition to high durability, these materials have precise bending and good weldability. After assembly, the skeletons are coated with powder paint to create a smooth, shiny surface and lasting protection.
The assembly process of the skeleton of the standard switchboard
Precise cutting with CNC machine:
The first step in assembling the electrical panel is the precise cutting of the skeleton parts. This operation is done using a CNC machine so that the smallest angles and dimensions can be implemented accurately and according to the technical plan.
Precise bending of sheets:
After cutting, the sheets are formed by hydraulic bending machines. At this stage, accuracy in the bending angle is very critical, because any slight error can cause a difference in the final assembly of the electrical panel.
Welding and frame assembly:
After preparing the parts, the welding operation is done. In Behran Tablo, CO₂ and spot welding are used to increase the strength of connections. After cooling, the welds are completely polished and smoothed so that the powder paint is uniformly placed on the surface.
Degreasing and electrostatic powder paint:
One of the key steps is to prepare the surface for paint. The skeleton is first placed in a defatting tub and then dried by compressed air. Next, electrostatic powder paint is sprayed on it and heated inside an industrial furnace to create a resistant and uniform surface.
Assembly of doors, locks and accessories:
After painting, doors, locks, hinges and other moving parts are carefully installed. At this stage, the alignment of the door, the uniform distance of the edges and the smooth operation of the locks should be checked so that the use of the panel is easy and standard.
Key technical points in assembling the electrical panel skeleton:
The alignment of the main frame:
One of the most important technical points in electrical panel assembly is the alignment of the main body. If the panel is not properly aligned, problems such as the door not closing or asymmetric pressure on the hinges will occur when installing internal equipment.
Choosing the right type of screws:
To increase durability and prevent rust, stainless or plated screws should be used. In the panels produced by Behran Tablo, all mechanical connections are made with corrosion-resistant galvanized screws.
Maintain a safe distance between internal equipment:
In the assembly of standard electrical panels, sufficient distance must be established between electrical components to avoid the risk of short circuit and overheating. The precise design of the equipment installation location in Behran Tablo engineering unit guarantees this issue.
Creating a suitable path for cables:
In the design of the skeleton of Behran Tabla electrical panel, the passage of the cables is pre-installed so that there is no need for re-drilling holes or physical changes during wiring. In addition to increasing safety, this makes the installation process faster and cleaner.
Using proper sealing in body seams:
To prevent the penetration of moisture and dust, resistant sealing tapes are used. In particular, the quality of the sealing has a direct effect on the life of the board.
Necessary standards in the production of electrical panel skeleton
The production of the skeleton of the electrical panel should be based on international standards, including:
Bahran Tablo Industrial Group complies with all these criteria in its design and production unit, so that every panel leaving the factory meets international standards in terms of safety, resistance and longevity.
The role of color in increasing the durability of the electrical panel skeleton
The color in the electrical panel is not only an appearance, but also plays an important protective role. Precise spraying of powder paint and its curing at a controlled temperature creates a surface resistant to scratches, moisture, chemicals and UV rays. This process is carried out fully automatically in the Behran Tablo factory in a controlled environment in order to achieve the highest possible quality.
