The Definition Of Switchgear Manufacturer

An electrical panel (switchgear) is a metal enclosure that holds a variety of electrical equipment. The main function of switchgear is to control electrical energy, protect other devices and equipment, and control the safe and simple electrical system of a complex. Making electrical panels requires high expertise and skills. For this purpose, it is necessary that a group consisting of qualified electrical engineers work in the design and drawing department. Also, in the production line, experienced technical technicians should make parts. Finally, in order to assemble and test efficiency and safety, the presence of quality control experts is very important. In this article, we will review the method of making electrical switchboards. Stay with CEED electric, the best manufacturer of switchgear.

What is a Panelboard?

A panelboard is an electricity supply system component that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure. It consists of a single panel or a group of wall-mounted panels. The goal of a panelboard is to split energy into different circuits.  They are similar to switchboards, but the structure is the factor that sets them apart. What makes panelboards different is that they are always mounted to the wall. The only possible way to access panelboards is through the front. The amperage of panelboards is much lower than switchboard and switchgear, 1200 Amp max. Panelboards are used for voltages up to 600 V.

Preparation Before Assembly

Careful evaluation before actual construction begins can avoid surprise problems later in the process.

1.Production Files

The designer should prepare the production files, including precise layout, bill of material (BOM), manufacturing drawings, front view drawing, single line diagram, command and control diagram and so on, to make the assembly job efficient and maintain a good quality level for the final production.

2.Component Availability Inventory

It is essential to have all the components available when the operators start the assembly in the workshop. Once the designer has confirmed the BOM, the supply chain team should be able to take action to prepare all the components accordingly. The assembly schedule should also be aligned with the larger production schedule.

3.Proper Workshop Space

A panel assembly workshop can take up a great deal of space, but it is critical to have it available when starting the assembly process. The workshop should include an area for the electrical panel, and space for components and feeding components. A well-prepared space can provide a proper environment for the assembly job.

4.Manpower Competency

All things considered, the most valuable resource we need to prepare is our people. We should make sure that enough workers have been assigned to a project so it will be possible to meet the final delivery date. You should consider the personal experience and individual capabilities of workers when assigning them to different projects. Regular training programs should be included to maintain competency and skills of the operators.

Steps Of Making Electrical Switchboards

In general, an industrial electrical panel in the electrical panel manufacturing workshop becomes as the final product in 6 steps from the initial idea. These steps are in order:

1. Design and preparation of isometric map (cubicle) and location (layout)

At this stage, after the initial negotiations and preparation of the draft contract, the expert of the switchgear manufacturing company will visit the site of the employer project. Then, by providing information to the design and engineering unit, in case of agreement on the generalities of the project and concluding a contract, the drawing work begins.

2. Welding, cutting, bending and drilling of the body

At this stage, based on the plan provided by the design and engineering unit, the production team will cut and build with stainless steel for the body of the switchgear. The thickness of the steel in this case is usually between 1.5 to 2.5 mm. The difference in this number depends on the type of application and the place of use of the device. Preliminary work on steel must be done with sensitive machines and with utmost care. This accuracy and sensitivity ensures the quality of the chassis and the body of the electrical panel.

3. Body painting

After preparing the body, in the continuation of the process of making the electrical panel, the workers paint and polish the body in several stages. In order to achieve the ideal quality, a variety of electrostatic coating paints are used. This is done at four stations:

Degreasing: With the help of chemical solutions or the use of ultrasonic system, the steel surface is removed from any grease that affects the quality of the paint.

De-rusting: By using milling or sanding, any rust on the sheet is cleaned. If the amount of rust is high, sulfuric acid can be used in a controlled amount.

Phosphating: The third stage of the painting process in the construction of electrical panels is dedicated to phosphating. This reduces the chance of rust on the metal surface.

Insulation: At the end of the painting process of the body of the electrical panel, insulation is done.

4. Assembling the skeleton and body of the electrical panel

After the body paint dries, the workers connect the skeleton and the body and embed different supporting parts in it. With the aim that the device is ready to place electrical equipment in a suitable place inside it.

5. Assembly of electrical parts and equipment and wiring

Finally, experienced technical technicians assemble all the equipment and wiring between them in a predetermined location inside the panel. Electrical components such as relays, contactors, sockets, circuit breakers, display panels, lights and warning signs, etc. are installed on the electrical panel. Also, the wiring and busbar required to complete the construction of the electrical panel is done.

6. Testing and quality control

After completing the process of making the switchgear, quality control experts will test the device with defined protocols. These tests include checking the appearance of the electrical panel and performing tests inside the factory. If the results of the inspections indicate the correctness of the production and assembly work, the machine will be sent to the relevant unit for packaging and delivery.
