400kVA Transformer Station Price: Detailed Insight and Overview

The price of a 400 kVA transformer station varies depending on type and technical requirements, from gantry, steel pole to complete Kios station. Understanding the influencing factors helps in making an optimal choice.

Types of 400kVA Transformer Stations

The 400 kVA transformer station comes in various types including gantry, steel pole, and complete Kios stations. Each type has different costs due to technical and material requirements. Gantry stations typically cost around 476,900,000 VND, steel pole stations about 529,000,000 VND, and complete Kios stations can reach 725,000,000 VND. Choosing the appropriate type depends on usage needs and influencing factors such as materials and installation location.

To deeply understand 400kVA transformer stations, first, we need to look at the common types on the market:

• 400kVA Gantry Station: This type of station is designed with high and low voltage equipment mounted on centrifugally cast concrete poles. The common version is a three-phase transformer with voltage levels of 15 kV / 0.4 kV or 22 kV / 0.4 kV. The primary application of the 400kVA gantry station is in areas lacking space and requiring high safety measures.

• 400kVA Dry Station: Uses cast resin transformers to prevent fires, highly valued in locations sensitive to fire, such as indoors, shopping centers, or industrial zones requiring strict safety.

• 400kVA Sealed Oil-type Station: Designed with a silicon steel core to minimize power loss and noise, with the ability to resist short circuits and withstand harsh weather. The 400kVA sealed oil-type station is usually found in places where performance and durability are prioritized.

• 400kVA Shihlin Station: Part of the dry transformer line, this station saves electricity, reduces noise, and CO2 emissions, suitable for places emphasizing environmental issues and fire safety.

All types of 400kVA transformer stations must strictly adhere to standards such as IEC 60076 and local regulations to ensure quality and operational efficiency.

Factors Affecting Transformer Station Prices

The price of a 400 kVA transformer station is influenced not only by the type of station but also by various other factors such as the configuration of oil or dry transformers, material requirements, installation location, and distance to the medium voltage line.

The price of a transformer station is not only a matter of configuration choice but is strongly influenced by technical and environmental factors. Some main factors affecting transformer station prices include transformer type, capacity, efficiency, cooling, and protection systems, construction location, and material quality.

Type of Transformer

The transformer is a critical component of the transformer station. With two main types: oil transformers and dry transformers, each offers unique cost and application characteristics.

• Oil transformers: Widely used due to economic cost and good outdoor performance. However, they require large spaces and environmental safety considerations.
• Dry transformers: Higher cost but safer, suitable for sensitive areas like residential zones without oil leak concerns.

Transformer Capacity

Capacity is decisive for the power transmission capability of the transformer station. A 400 kVA transformer station requires quality components to ensure operational efficiency and safety, thus affecting the final cost.

Transformer Efficiency

Efficiency is also critical in minimizing energy losses. High-efficiency transformers require quality technology and materials, impacting the initial cost.

Cooling and Protection Systems

Cooling and protection systems play a vital role in maintaining stable and safe operations for the transformer station. More complex systems, such as fan or oil cooling, increase costs due to design and operational requirements.

Location and Construction Conditions

Constructing transformer stations in difficult-to-reach locations or complex geological conditions can lead to increased costs, requiring specialized equipment and experienced technical teams.

Material Quality and Origin

Choosing materials from reliable suppliers like EEMC, ABB, Mitsubishi, Schneider ensures quality and durability, although it may increase the station’s cost. Reputation and quality are essential factors for long-term investment.

Choosing the Appropriate transformer station Configuration

When choosing the configuration of a 400kVA transformer station, customers should consider technical and economic suitability. For example, a 3-phase auto-transformer by Lioa costs around 90,000,000 VND, while the isolating type costs around 115,000,000 VND. Both include an 18-month warranty and free installation service. The configuration choice should be based on specific project needs and usage locations.

Choosing the transformer station configuration is crucial for ensuring the electrical system’s efficient and safe operation. This decision requires careful analysis of technical factors and system requirements. To choose a suitable transformer station, attention must be paid to many technical parameters and actual conditions.

Regarding choosing a transformer station, some important parameters like rated power, input/output voltage, operational frequency, energy conversion efficiency, and power factor need careful consideration.

• Transformer capacity: A necessary factor to meet the actual load demand, not too high to avoid unnecessary losses and costs. Generally, the transformer capacity should be large enough to handle the maximum load, with a backup in case of a fault.
• Input and output voltage: Must match the system’s voltage level, comprising 110kV, 220kV down to medium voltage like 10kV or 22kV according to system requirements.

Besides, the location and design of the transformer station are noteworthy. The station site should be chosen near the load center to minimize energy losses and installation and operation costs. The station design must meet electrical safety requirements, not affect aesthetics, and be easy to access for maintenance.

A fire prevention system is indispensable in the transformer station configuration. This system must be effective and ready to handle emergencies, especially in high-risk fire areas.

Finally, popular transformer station types include intermediate transformer stations and workshop transformer stations, each with specific applications and design requirements suited for specific usage objectives.

Understanding prices and evaluating various types of 400kVA transformer stations offer significant technical benefits, cost optimization, and ensure long-term investment efficiency. Smart investment helps maintain stable electrical system operations.
