In-depth on Substations
Quanganhcons specializes in building and upgrading substations, providing stable and reliable power for factories, industrial zones, and the electrical grid. Focusing on advanced technology and prioritizing safety and efficiency has made the company a top choice for large projects.
Substations are an essential component in the electrical distribution system, converting voltage through electromagnetic induction. Serving as an intermediary between power plants and consumption points, substations ensure optimal performance and safety for the grid.
Substation Structure
- Transformers: The main device that switches voltage from high to low or vice versa.
- Busbars and disconnect switches: Help disconnect circuits and isolate equipment for maintenance.
- Surge protection systems: Protect equipment from overvoltage due to lightning and grid faults.
- Grounding systems: Minimize electric shock risk and equipment damage.
- Distribution area: Responsible for branching power to medium/low voltage lines.
Substation Design Requirements
Substation design requires certain key factors for efficiency and safety:
- Substation location: Should be centrally located to reduce power loss.
- Investment cost: Consider station capacity, materials used, and technology applied.
- Safety: Ensure safe distance to residential areas, integrating fault warning systems.
Substation Classification
There are three common types of substations:
- Transmission stations: Connect high voltage grids, used for electrical transmission over long distances, 110kV to 500kV.
- Intermediate (load) stations: Convert medium voltage (22kV-35kV) to low voltage.
- Distribution stations: Supply low voltage (0.4kV-11kV) directly to consumers.
Operating Principles
Substations operate based on electromagnetic induction, where input voltage is adjusted through transformers according to distribution phase requirements.
Practical Application
- National grid: Connects large power plants to urban centers.
- Industry: Provides stable power sources for industrial zones and factories.
- Civil: Reliably distributes electricity to households.
Standards and Development Trends
Current substations must comply with IEC 61850 standards to ensure automation and operational safety. GIS (Gas-Insulated Switchgear) technology using SF6 gas is being applied to reduce installation space. Additionally, integrating artificial intelligence (AI) helps monitor and predict potential incidents through operational data analysis.

Core Values and Quality Commitment
Quanganhcons is committed to providing high-quality solutions, ensuring safety and efficiency in all projects. The company uses advanced technology to create modern and reliable projects while always putting customers at the center of activities, creating long-term value for them.
In the context of continuous development in the construction and energy sector, clearly defining core values and quality commitments is a foundational element for building a reputation and sustainable competition. These values are not only reflected in each product and service but are also deeply ingrained in the corporate culture, strongly influencing the working methods and decisions of each individual in the organization.
Core Values: A Solid Foundation
Core values like product quality, customer dedication, social responsibility, and innovation not only shape management art but also serve as a basis for developing long-term strategies. For example, customer dedication is expressed through listening and meeting needs in the most detailed manner, thereby creating suitable and effective solutions.
Quality Commitment: Building Trust
Quality commitment is the affirmation of the ability to provide products and services meeting the highest standards. This not only builds customer trust but also acts as an internal motivation pushing employees to give their utmost effort in daily work. Ensuring product quality is the way the company asserts its position in the industry.
The Link Between Two Factors
The quality commitment process is how the company implements its core values. If quality and sustainable development are the goals, then social responsibility will be the method they use to meet those expectations. Therefore, core values and quality commitment cannot be separated when shaping and developing corporate culture.
Practical Examples
- Quality: Many companies apply strict management systems like ISO 9001 to ensure every product and service meets the highest quality.
- Customer dedication: Through the application of modern technology like ERP software to manage and serve customers best, companies have built a solid foundation of trust.
