What is an industrial electrical cabinet?

To understand what industrial electrical cabinets are? First, let’s learn about electrical cabinets.

– The electrical cabinet is an area for electrical equipment, circuit breakers, connectors, etc. to have the function of controlling the power supply system for the load system. Depending on the location and needs of use, the cabinet will have a square or rectangular shape.

– Industrial electrical cabinets are cabinets used in industries and must ensure stability, durability, continuous operation and accuracy for a long time in many different environments.

Industrial electrical cabinet system

– In addition, this is also a place to supply electricity with large capacity, it usually has a larger structure than a small household electrical cabinet, the connection system and control circuit structure is quite complicated.

– With the development of the market, there are many types of industrial electrical cabinets. Depending on the need or application, there are different types of electrical cabinets such as: network cabinets, telecommunications cabinets, control cabinets …

Effect of electrical cabinets

Industrial electrical cabinets have 3 basic effects which are:

– Used to control the electronic system of equipment and the entire electrical cabinet system such as: Control and distribution cabinets.

– Assembled in industrial zones to bring safety to users. Therefore, most electrical cabinets are manufactured by modern technology lines, ensuring IEC international standards.

Moreover, it will also supply continuous power to the electrical system for the machine system to work properly.

Application of electrical cabinets in life

– Used to control engines and machinery, in order to create conditions for the machine to operate efficiently. This type of cabinet has high durability, large capacity and it is used in many factories, water pumping plants, industrial parks.

– Moreover, electrical cabinets are also used in general electrical engineering rooms, buildings, factories and commercial centers. It is also used in low voltage electrical networks.

– Industrial electrical cabinets are also placed in public areas such as flower gardens, parks, urban areas and some other outdoor spaces.

Industrial lighting cabinets can be installed in public places

Industrial electrical cabinets include what?

– All electrical cabinets have a push button design on the front of the cabinet for convenient operation.

– On the other hand, it is also equipped with an emergency stop button, which switches off all electrical circuits whenever the electrical system has a problem.

– Electromagnetic relay parts in industrial electrical cabinets are often used in control systems with contacts. For example: Normally open contact, common contact, spring, coil, magnetic circuit…

Contactor Used to control and switch motors, the machine is used in industrial and civil electricity. There are two types of switches: single switch or multi switch, made up of 2 points and used to open and close circuit breakers or switches.

Aptomat is a kind of protective device, it can prevent overload, short circuit, leakage current and help the electrical cabinet to operate well. Normally, aptomat is used to protect against overload or short circuit for electric motors.

– Part of the dust filter, the electric cabinet exhaust fan can cool the components inside the industrial electrical cabinet.

In addition, there are other protective devices in industrial electrical cabinets such as protective relays, indicator lights…

Fire protection pump cabinet

The structure of the device includes:

– Signal phase light

– Supply voltage 3P-380V

– Voltage, current measurement

– Report loss of phase

– Standard IP20 – IP54

This electrical cabinet is made of 2mm thick corrugated iron, plays an important role in the electrical equipment system. Because it has an alarm function, supplying power to the fire fighting water pump.

Fire pump electrical cabinet

Lighting control cabinet

Has the following structure:

– Standard IP 43 – IP 55

– Sheet metal meets G3302 (Japan), En10142 (Europe), and ASTM A653/A653-08 (USA) standards.

– The time relay is set to turn on and off the lighting device according to the preset program

Lighting capacitors provide and control electric lighting systems in public areas such as parks, roads, apartments, hospitals…
