Industrial electricity plays an important, indispensable role in human production and daily activities. The basic tasks of industrial electricity are connecting and installing industrial electrical signal transmission systems, operating microcontroller programming devices, operating LPC programming devices, operating and maintaining industrial electrical equipment,… The article below by Dang Phat Construction introduces you to the process of
industrial electrical system design and installation construction and things to know before installing industrial electricity.
What is an industrial electrical system?
Industrial electricity plays an indispensable role in today’s life from production, business to everyone’s daily living activities.
Industrial electrical systems help guarantee stable operation for power sources and develop reasonable, safe, and effective electrical transmission systems to serve agricultural and industrial production activities, commercial services, and civil life.

What does an industrial electrical system include?
Grasping the components of industrial electrical systems before system installation will help us optimize construction time, thereby improving efficiency and reducing installation costs.
Depending on the characteristics of each plant and production workshop, the
industrial electrical system will have many parts corresponding to different functions and tasks. It can be divided into the following components:
Medium voltage system supplying power to the main transformer: This is the transformer component to convert electricity from the national grid to serve business production. This system aims to stabilize currents and adjust increasing or decreasing voltage to appropriate levels. Thanks to this, machinery and equipment in the workshop can operate effectively.
Distribution electrical cabinet system: Is the system installed to manage electricity circulation in workshops to ensure safety for industrial devices and machinery.
Industrial equipment electrical cabinet system: Is the control cabinet system aiming to adjust switching on and off power sources for industrial electrical devices. Equipment cabinets usually include: Ammeters, Voltmeters, fuses,… to ensure safety for machinery and equipment.
Industrial equipment system: This is the core part, directly affecting business production. Industrial electrical equipment systems include: machinery equipment directly participating in the production process (production, processing, packaging line systems…) and other power-using parts (lighting, air conditioning, ventilation systems…).
What role does an industrial electrical system play?
The role of electrical systems in industry is very important in production and factory operations of each enterprise, we can list prominent roles as follows:
- Replace humans, performing things that humans cannot do manually.
- Improve techniques during usage, increasing industrial equipment productivity. Ensure staff carry out continuous, uninterrupted production processes.
- Save labor power.
- Reduce production costs to a significant level, lower product costs, and improve quality.
- Bring modern techniques into machinery systems, being more dynamic to help save time.
- Prices are appropriate to product manufacturing processes.
What criteria are needed for industrial electrical installation?
Before industrial electrical system design and installation construction, we need to fully ensure the following requirements:
- 1. Handed over devices need to meet electrical safety criteria. Avoid causing unsafety during operations and usage.
- 2. The system operates smoothly and effectively. This criterion is evaluated by system working capacity. It needs to guarantee not to affect the production progress of businesses.
- 3. Save operational costs: Need to calculate correctly the scale and capacity needed for use. Study layout and use correct devices, avoiding wasting electricity.
- 4. Meet state standards: Used industrial electrical systems need to ensure standards such as TCVN 7447-5-51: 2010, TCVN 394:2007.
Standard industrial electrical installation construction process
In workshops, electrical systems play a very important role deciding activities of the whole plant.
Industrial electrical installation according to correct processes guarantees functionality as well as safety for plant activities. Below are steps to construct electrical systems in workshops.
1. Prepare necessary equipment
Unlike civil electricity, industrial electrical systems need to prepare specialized devices, specifically as follows:
–
Conductors: Calculate quantities and lengths of 1-phase and 3-phase wires needed to pull electricity into workshops from outside power sources.
–
Electrical cabinets: Inside plants, many types of electrical cabinets are used and need counting for preparation.
–
Transformers: Indispensable in any industrial electrical system using high voltage 380V. This helps the stability of power sources supplied to plants.
–
Protective devices: Circuit breakers (Aptomat), electrical switches, Relays, to guarantee safety for operators.
–
Signal alarm: In case plants operate and encounter electrical incidents, signal lights and alarm bells are needed to emit warnings, ensuring safety and fast incident fixes.
2. Survey actual projects, receive information from customers
What does an industrial electrical system have?
General
industrial electrical systems nowadays include some main parts such as:
- Workshop electrical cabinets used in industry
- Automatic control systems, measuring boiler parameters at thermal power plants
- Some automation systems such as: Hydrogen production in thermal power plants, raw water treatment in thermal power plants, demineralized water treatment in thermal power plants, wastewater treatment in thermal power plants
- Oil burner control system
- Low voltage and medium voltage soft starters
- Automatic coal supply control system in thermal power plants
- Automatic ash and slag handling control system
3. Design electrical system drawings
Below are some criteria helping you have a standard-compliant electrical system construction drawing:
- Perform correctly the standards on language and symbols used in electrical technical drawings
- Safety factors are placed foremost during construction
- Respond correctly to set plans according to initial commitments with investors
- Choose optimal options to execute construction quickly, saving costs
4. Construct and install industrial electricity
Constructing and installing electrical systems is foremost important in the whole process. When constructing, executing units need to guarantee the factors below:
- Construct according to correct approved design drawings.
- Ensure safety levels of the system during operations.
- Commit on effectiveness in activities of devices in the system
- Be easy in repairing and maintaining industrial electrical systems later
5. Inspect and accept
- After completing construction, trial running on real systems is needed to check safety levels. Check power supply capabilities for devices to see if they guarantee set requirements. After that, proceed with acceptance inspection and transfer to enterprises.
- When the trial run system is stable and safe, construction units will proceed to transfer electrical systems to owners, starting into warranty and maintenance periods after industrial electrical system installation.
Industrial electrical installation accessories
Relay socket
Most commonly used are electromagnetic relays which have main parts like coils, magnetic circuits, contacts, and shells. Magnetic circuits are also manufactured from iron material with two main parts: a stationary frame part and a moving part made of U-shaped steel plates. The moving part will link mechanically with the positive contact.
The difference that can be noticed between electromagnetic relays and contactors is that electronic relays have a type of control contact that is normally closed or open, without arc suppression and also without contact compression springs, but only use copper bars at contacts to create compression force.
Reputable industrial electrical system design and installation construction unit
Electrical systems in general and industrial electricity in particular play an important role in construction. Because of this, at construction projects for plants, enterprises, houses, electricity and water are separated into separate stages, requiring technical design in a scientific manner in deploying paths for electricity and water. This process requires responding to strict standards because just a small oversight at technical stages can leave complex and very unpredictable consequences.
