Constructing a modern plant electrical system is a complex service that requires a lot of coordination between science and technology. The goal is to ensure that the plant electrical system operates stably, efficiently, and safely. In this process, the crucial steps include survey and preparation, design, construction, and acceptance.

1. Survey and Preparation

Surveying the current status of the site and collecting data on electrical demand is the foundational step to design an efficient industrial electrical system. This process also includes selecting quality materials and equipment from reputable brands such as Schneider, ABB, Mitsubishi, ensuring optimal safety and quality.

2. Electrical System Design

The design of a modern plant electrical system should be divided into main areas:

• High voltage electrical network: Detailed design of the power line and transformer station, ensuring safe connections from the national grid.
• Low voltage electrical network: Distributing electricity to devices with voltages below 1kV, along with control panels.
• Industrial lighting system: Reasonably arranged to optimize energy consumption.
• Lightweight electrical system: Includes concealed electrical wires, electrical cabinets, and designs complying with strict standards.

3. Construction and Installation

This process requires strict adherence to professional procedures in plant electrical construction. The important steps include installing the electrical network, main distribution boards, lighting systems, and other electrical devices according to approved design drawings.

4. Acceptance and Handover

After completing the installation, the electrical system needs to be tested and trialed to ensure stable and safe operation. This process also includes handover and receiving feedback from the investor, contributing to optimizing the system.

In industrial electrical construction, ensuring plant electrical safety and optimizing cost, energy savings are top priorities to enhance plant operational efficiency.

Comprehensive industrial transformer station construction

QuangAnhcons executes comprehensive construction of transformer stations from medium to low voltage up to 35kV, including various station types such as pole-mounted, frame, mono steel pole, foundation, room, and integrated kios stations. The materials used have clear origins and CO&CQ certifications, ensuring electrical system safety when energizing the grid.

Comprehensive construction of industrial transformer stations is a complex process involving many crucial stages, each with a decisive impact on the efficiency and safety of the entire medium-voltage electrical system.

The transformer station construction process includes the main steps:

1. Field survey and station foundation positioning: This process aims to identify the optimal position for the industrial transformer station and underground medium-voltage cable routes. The survey requires highly skilled technicians to ensure accuracy and effectiveness in constructing the transformer station.

2. Construction preparation and materials: In this phase, all equipment, machinery, and materials are fully prepared, all inspected according to technical standards to ensure suitability with the design.

3. Foundation construction and grounding system: Foundation construction includes excavation, concrete pouring, and installation of medium-voltage cable protection pipes. The grounding system is carried out according to standards to ensure electrical safety for the entire industrial transformer station.

4. Installing equipment and structures within the station: Equipment such as switches, working benches, beams, insulators, and transformers will be installed meticulously, complying with technical regulations to protect sensitive components and ensure optimal electrical safety.

5. Cable pulling and connections: The process of pulling medium-voltage cables and connecting devices according to the design diagram is a decisive step in ensuring the electrical system works stably and efficiently.

6. Testing, calibration, and internal acceptance: This is the completion step to check and ensure the technical parameters of the industrial transformer station meet standards. Any necessary adjustments will be made to ensure the station meets the most stringent requirements before going into actual operation.

7. Trial energizing and handover: Finally, after completing the above steps, the transformer station will be tested through trial energizing. Filing the acceptance documents and handing them over to the investor is the final step in the process, ensuring the industrial transformer station is ready for operation.

By fully and thoroughly executing these steps, the comprehensive construction process of the industrial transformer station provides high safety and efficiency, meeting standards for medium-voltage electrical and electrical safety systems.

Detailed Electrical System Installation for Factory Machinery

QuangAnhcons specializes in the detailed installation of electrical systems from the transformer station to machinery in the factory, ensuring timely and high quality. With extensive experience, the company commits to meeting the best technical and safety requirements, enhancing production efficiency.

Installing a detailed electrical system for factory machinery is a complex process, combining many professional technical steps to ensure the electrical system operates stably and safely. This is one of the most important tasks in constructing and operating a modern manufacturing plant.

Industrial electrical system installation process for factory machinery

1. Preparation and site survey: In the first step, reading and thoroughly understanding the factory electrical system design drawings is crucial. Based on that drawing, prepare complete materials and equipment, such as electrical cables, electrical cabinets, electrical protection devices, copper busbars, contactors, PLC…

2. Installing devices into electrical cabinets: Use cable trays and rails to mount control and motor control devices like MCBs, contactors… Fabricating copper busbars demands precise craftsmanship according to connection diagrams to ensure the system’s efficiency.

3. Install wiring and electrical conduits: Install concealed pipes in walls, underground concrete floors, or use cable trays like Cadivi, LS to optimize space and protect industrial electrical safety.

4. Connect and secure the system: Proceed to wire connections with devices and control panels according to technical diagrams. Ensure wires run neatly and logically for convenient future maintenance.

5. Inspection, trial operation, and acceptance: Conduct a preliminary inspection of the entire system to ensure joints, insulation, and grounding are safe. Power up and test functions from switching on/off to protective device operations like anti-shock CBs, fuses, ensuring the system operates as originally designed.

Important notes when installing plant electrical systems

• Labor safety is the top priority, strictly adhering to industrial electrical safety regulations.
• Design compliance: Do not alter diagrams or materials to avoid future issues.
• Optimize efficiency: Reasonable wiring helps minimize energy loss during operation.
• Easy maintenance: A well-designed system will aid in simple and effective maintenance.
• Ensure durability: Use materials like Cadivi cables, ABB to resist corrosion and interference in harsh environments.

Technical specifications & frequently used equipment

• Copper busbars: The main component distributing electricity within the system, requiring precise fabrication and installation.
• Industrial electrical cabinets: Integrates devices like MCB, circuit breakers, relays, PLC; ensures control functions and safety protection.
• Electrical cables: Chosen according to insulation standards and suitable capacity for devices.
• Protective devices: CBs, overload relays, protect users from risks of electric shock and overload.
