Low voltage switchboards and some notes when installing

Every day, we often see a lot of electrical cabinets, but we don't know what it is. How the manufacturing and installation process works. Today, we would like to send you the article "Low voltage cabinet and some notes when installing". Hope to help you in choosing and ordering products.

1. Low voltage switchboard

Low voltage switchboards play an important role in civil and industrial projects. We know that right after the low voltage stations are low voltage distribution cabinets. The main function is switching, safety protection for the load system. In civil as well as in industry, standard power is used after these substations. All electrical cabinets installed behind the station are called low voltage cabinets.

With the task of supplying electricity is divided into separate circuits. Each of them is managed and secured by fuses or devices such as cutting machines, aptomat .... Low voltage switchboards are divided into several functional parts. Includes electrical and mechanical components. Facilitate the completion of a utility. Low voltage switchboards are an important part of ensuring the safety of electrical systems.

2. Some notes when installing:

Low voltage switchboards are an integral part of the entire electrical system in civil as well as in industry. So when installing at the factory, we have to pay attention to the following points:

• About mechanics:

1. Produce in accordance with design drawings approved by customers. When detecting that there are non-deployable positions, it is necessary to report back to the technical department for the most optimal plan.
2. When selecting a sheet to process low voltage cabinet, note that the corrugated iron sheets must be beautiful. No warping or wavy, deformed wings or hips will not be installed.
3. When punching the low-voltage cabinet doors, attention should be paid to details such as: Phase indicator, clock face, switch, and Aptomat hole positions. The parts must be broken at the right position, size, avoid being punched into the workpiece, leading to a loss of hole system. It will be impossible to install the devices when connecting.
4. Seismic folding, folding details of low voltage cabinet after punching. The parts are designed to be suitable for CN and pestle mortar machines so that when machining is easiest. Complete details must ensure the right size, square and no warping.
5. Welding, grinding and finishing low voltage cabinets. This stage is quite important, it is the last stage before painting so the details must be accurate and aesthetic. The welds must be beautiful but firm, covering the position of the gap caused by the folding.
6. Electrostatic paint finishes the product surface. With electrostatic painting technology automatically with seven sides to handle before putting into the paint chamber. We always produce kilns of low voltage switchboards that are durable and meet the schedule.

• About the electric workshop:

1. After the low voltage cabinet is completed, mechanical part is completed. The electric workshop will assemble the wings, the body, complete the cabinet
2. Attach devices such as Aptomat, magnetic start, clock, switch, indicator light ...
3. The rails catch the device, the plastic trough is also installed up before connecting
4. After completing all the details, proceed to connect the low voltage cabinet according to the design drawing diagram. The circuits are connected in detail and carefully. The wires are neatly and neatly arranged in plastic troughs, to avoid tangling when repairing.
5. Test and test cool before putting power into the test. This stage is important and determines the whole quality of low voltage cabinets. Therefore, engineers need to check carefully, avoid mistakes will lead to fire and danger to life and property.
6. Finally, complete the labels and packaging to ship.
