Efficient and Safe Factory Electrical System Installation Procedure

Installing a factory electrical system is a complex process requiring precision and compliance with technical regulations to ensure safety and performance.

Prepare necessary equipment for the factory electrical system

Installing a factory electrical system requires transformers to convert the appropriate voltage, using various industrial electrical cabinets for distribution and control. The electrical wiring must be accurately calculated for quantity and length to supply sufficient power. Protective devices such as circuit breakers, fuses, and relays are necessary to ensure safety and protect the system from incidents.

In order to build an effective and stable factory electrical system, preparing the necessary equipment is crucial to ensure optimal power supply and management.

• Transformers and Medium and Low Voltage Cabinets: Transformers play a key role in converting different voltage levels to suit the needs of the factory electrical system. Medium and low voltage cabinets ensure power distribution to different areas, equipment, and machinery, helping to optimize production activity.
• Power Distribution Cabinets: Power distribution (DB) cabinets aim to distribute electricity to each consumption area. Along with that, control cabinets accurately perform control for the machinery to enhance the efficiency of the factory operation.
• Generator and Transfer Switch Systems: Generators play an important role in providing backup power, helping factory operations not be interrupted during grid failures. The transfer switch ensures smooth conversion between main and backup power sources.
• Electrical Motors and Equipment: The use of electric motors, pumps, and compressors is indispensable for the operation of machinery and equipment. They help optimize the production process and reduce energy costs.
• Light Electrical Systems: This system primarily provides power to lighting equipment, air conditioning, and communication devices. Designed to use low voltage, usually single-phase or 220V, the light electrical system supports auxiliary activities but is no less important.
• Operation and Safety Systems: Setting up an operational and safety monitoring system to ensure the entire factory electrical system operates efficiently is essential. This helps minimize risks related to electrical incidents.

Factory Electrical System Design

Calculating the power consumption of equipment and machinery helps select the suitable equipment for the factory electrical system. Designing high and low voltage networks plays a crucial role in transmitting electricity from the national grid into the factory, ensuring power is supplied to all devices under 1kV.

Designing a factory electrical system is a core part of industrial infrastructure, optimized to ensure the safety and performance of equipment and machinery in the production environment.

Calculate Total Power Consumption

It starts with calculating the total power consumption of all equipment and machinery is essential. This allows choosing and implementing appropriate technical solutions, supporting the factory’s electrical system to operate effectively. Accurately identifying power helps choose the right electrical cables, and transformers from reputable brands like ABB or Schneider to ensure stability.

High Voltage Network Design

The high voltage network is responsible for transmitting electrical energy from the national grid to the factory. A detailed design of this system is extremely important to ensure continuity and safety in electricity transmission. The layout of high voltage lines and substations must be performed reasonably to enhance electrical efficiency.

Low Voltage Network Design

The low voltage network, with voltage levels below 1kV, sets the installation of control cabinets to be reasonable and safe. This helps supply electricity to the equipment in the factory optimally, creating the best conditions for the production to run smoothly.

Lighting System Design

The industrial lighting system must be calculated so that the number of lights adequately meets production needs but does not waste energy. Insufficient or excessive lighting can be detrimental to the production process, so careful consideration is necessary to achieve balance.

Preliminary Design and Approval Process

The preliminary design process includes creating an overall model, arranging installation areas and equipment. The design must be clear and accurate in terms of scale. After completing the preliminary design, approval from the customer is necessary. This helps adjust details to fit reality and optimize estimated costs.

Designing a factory electrical system not only includes the perfect coordination between power consumption calculation and network but also requires continuous approval and adjustment to ensure uninterrupted operation and long-term cost savings.

Installation and construction of the factory electrical system

Construction of source cables after the transformer substation and careful installation of cable trays for stability and protection. Industrial electrical cabinets must be accurately installed as these are the centers for power distribution and control. Light electrical systems such as fire alarms and lighting also play an important role.

Installing and constructing a factory electrical system is an important task that requires not only professional skills but also strict compliance with technical regulations. When carrying out industrial electrical construction, there are a few essential steps to ensure stable and safe operation of the entire system.

Calculate Total Power and Design Electrical System

1. Calculate total power consumption: First, designing the electrical system starts with calculating the total power consumption to ensure the appropriate selection of equipment such as transformers from brands like Thibidi or ABB.
2. Design high voltage and low voltage networks: The high voltage network must ensure stability, while the low voltage (below 1kV) system needs meticulous planning to suit production requirements.
3. Design lighting and light electrical systems: The lighting system must optimize the power supply, ensuring sufficient light without wasting resources.

Equipment Preparation

Installing a factory electrical system requires specialized equipment such as industrial electrical cabinets, wiring from brands like Cadivi or Schneider, and protective devices like circuit breakers and fuses. These are crucial elements to protect and operate the source cable system effectively.

Construction of Light Electrical and Cable Systems

• Construction of main source cable system: Electrical cables need to be underground in metal or PVC pipes to ensure safety and durability.
• Installation of cable trays: Cable trays are indispensable for fixing large electrical wires, ensuring neatness and maximum protection.
• Install industrial electrical cabinets: As the center of power distribution, it needs precise setup to ensure efficient and safe operation.

Construction of Lighting System

The light electrical system not only includes lighting but also other technologies like fire alarms, playing an important role in ensuring safety.

Acceptance and Testing

After installation, testing and acceptance are mandatory to ensure the system meets safety and performance standards before official operation.

Throughout the construction process, principles such as:

• Labor and equipment safety.
• Strict adherence to technical standards and professional processes.
• Cost and operational efficiency optimization.

The installation of a factory electrical system not only ensures the safety and efficiency of the production process but also is a strategic investment that needs to be carried out according to the correct procedure. Technical preparation and periodic maintenance are factors determining the efficiency and longevity of the system.
