Industrial Electrical Design: Process and Key Factors

Industrial electrical design is a complex process that involves planning and executing electrical systems for factories and industrial facilities, with a high demand for safety and efficiency.

Effective Industrial Electrical Design Process

Industrial electrical design begins with research and data collection, determining energy requirements and specific technical needs. Preliminary design drawings are created to display the overall layout of the electrical system, including the location of main equipment such as electrical cabinets, cables, and lighting. The drawings are submitted for approval to ensure reasonable equipment arrangement and operational cost. Finally, the design is standardized, meeting safety requirements and state regulations, along with calculating electrical load balance for efficient system operation.

1. Receive Customer Information

   Industrial electrical design starts by receiving client requirements, including detailed information about the project such as space area, number of workers, and equipment to be used. Site surveys are conducted to verify data accuracy, laying a solid foundation for the next stages.

2. Consultation and Plan Development

   Based on collected data, experts analyze and propose solutions to ensure sufficient energy supply to the industrial electrical system. This process includes calculating and allocating the installation of the electrical system, ensuring aesthetics, cost-efficiency, and safety. The most suitable plan is selected for the next steps.

3. Detailed Design

   Creating detailed technical electrical drawings is the next step, including calculations of the distance between devices, cable layout, and necessary safety factors. High-quality materials from reputable brands like Cadivi or Schneider are chosen to ensure performance and durability for the system.

4. Industrial Electrical Cabinet Design

   The block diagram plays a critical role in designing the electrical cabinet, along with calculations of load and energy demand forecasts to ensure load balance.

5. Inspection and Approval

   The technical drawing inspection is conducted thoroughly to ensure compliance with technical and safety requirements. Any necessary adjustments are made before the drawings are officially approved.

6. Construction and Testing

   The construction process proceeds according to the approved designs, accompanied by strict safety inspections to prevent risks during the operation of the industrial electrical system.

Safety and Efficiency Factors in Design

Safety is the foremost factor in industrial electrical design. The system must comply with safety regulations and ensure user safety. Efficiency is ensured through electrical load balancing and energy utilization optimization. Cable tray design not only needs to be safe but also aesthetic. Lighting systems are designed according to each area to maximize utility and efficiency.

Safety Factors

Ensuring safety in architecture and interior design is an indispensable foundation for any construction.

• Safety During Fire: An effective fire alarm system, clear escape routes, and explosion-proof design are necessary to ensure user safety (1)(5).
• Electrical Safety: The electrical system must adhere to safety standards to avoid electrical faults. Protective devices like fuses and circuit breakers must be integrated into the electrical safety design (1)(5).
• Child Safety: Interiors should use safe materials, minimizing sharp corners, with special attention to window and balcony design to prevent accidents (1)(5).
• General Safety: Safety for construction not only concerns the users but also the construction process. Installing alarm systems, surveillance cameras, and security control rooms is essential (2)(3).

Efficiency Factors

Efficiency in design is a crucial factor, ensuring optimal operation of the project in terms of energy and function.

• Usage Efficiency: Optimizing space provides high convenience and better functional usage (4).
• Technical Safety Assurance: Designs must comply with technical standards and use high-quality materials. This ensures safety and energy efficiency standards are met during construction (4)(3).
• Aesthetic Criteria: The combination of safety and aesthetics in design helps create an appealing, safe, and convenient living and working environment (4)(5).
• Labor Safety Organization: The construction process must strictly follow labor safety regulations. Drawing up plans and implementing safety measures is indispensable (3).

Energy Demand Forecast and System Renovation

Forecasting energy demand is a strategic task to maintain stable operation of industrial electrical systems. Long-term energy planning and anticipating methods for renovation and upgrading systems in the future are essential. This ensures the system continually meets increasing usage demands and maintains sustainability.

In the context of rapid economic growth, forecasting electricity demand becomes extremely important. Accordingly, by 2025, increased electricity demand is projected to rise by approximately 12-13% compared to the previous year, playing a significant role in economic and industrial development. With each 1% economic growth, electricity demand increases by 1.5%, indicating a close relationship between these two factors.

Electricity production in 2025 is projected to reach about 347 billion kWh, an increase of approximately 37 billion kWh compared to 2024, indicating a growing trend in the electricity industry. To meet this demand, renovating the current electrical system is crucial.

Electrical System Renovation Solutions

• Power Supply Solutions: Ensuring fuel supply for power generation, as well as completing major repairs before the dry season is essential to maintain stable power supply.
• Renewable Energy Development: Maximizing the mobilization of renewable energy plants to meet load demand and optimize system capacity.
• Enhancing Backup Power Sources: Gas, hydropower, and electricity trading from Laos serve as backup solutions to meet power demands during peak periods.
• Electrical System Management and Operation: The Ministry of Industry and Trade has approved the early operation plan for the 2025 electrical system to optimize management efficiency.

Challenges and Solutions

Power supply in 2025 faces many challenges due to high electricity demand growth and external factors such as climate conditions and fuel sources.

Solutions for this situation include strongly developing renewable energy, enhancing electric efficiency, and applying smart electrical system management technology to optimize supply.

Forecasting electricity demand and renovating systems is a solid foundation helping electricity industry enterprises effectively plan long-term, especially in a sustainable power development path.

The optimized industrial electrical design process brings technical and strategic benefits to production facilities. Safety, efficiency, and compliance with standards help systems meet maximum industrial demands.
