Quotation for 2000kVA Transformer Station: Important Factors

Transformer station 2000kVA is an essential device in the electrical system, responsible for voltage transformation to provide stable energy for production and residential areas.

Introduction to 2000kVA Transformer

The 2000kVA transformer station is a crucial piece of equipment in the electrical system, playing a role in transforming high to low voltage to supply stable energy to areas or production facilities. This transformer station is often used in residential areas, medical facilities, and manufacturing plants that require a medium power supply to ensure optimal economic and technical efficiency.

The 2000kVA transformer station plays a key role in the power distribution system, allowing the transformation of voltage from a medium level like 22kV or 35kV down to low voltage 0.4kV. This is an essential requirement to meet the power demands of applications such as residential areas and manufacturing plants.

Technical Specifications of the 2000kVA Transformer Station

A transformer station with a 2000kVA electric power often uses transformers with a primary voltage of 22kV and a secondary voltage of 0.4kV. This characteristic ensures efficient power distribution in areas with large power demand. The structure of the station includes transformers, busbar systems, isolators, and protective devices like earthing and surge protection systems, all designed to ensure maximum safety.

The 2000kVA transformer stations are classified into two main types:

• Outdoor Transformer Station: Suitable for large-scale industrial zones and factories due to its size and cost-saving advantages.
• Indoor Transformer Station: Commonly used in urban areas, where space and safety are prioritized.

Practical Applications

There are three main application types that a 2000kVA transformer station can support:

1. Outdoor: Typically deployed in factories and industrial zones.
2. Indoor: Suitable for urban areas and institutions that require environmental protection.
3. Pad-Mounted Station: Installed in export processing zones and industries with high power demands.

Main Technical Specifications

These transformer stations usually have large sizes, requiring a minimum area of 16m² for installation. The rated frequency is 50Hz, complying with standards and electrical systems applied in various countries. This product is manufactured according to international standards such as IEC to ensure efficiency and safety in use.

Due to its flexibility and stable power supply capability, the 2000kVA transformer station has become an ideal solution for even the most demanding industrial environments.

Types of Transformer Stations and Applications

The 2000kVA transformer station comes in various types, such as outdoor, indoor, and underground. Each type has its applications. Outdoor stations often have lower construction costs and are used in open areas like residential neighborhoods. Indoor stations are suitable for urban areas or manufacturing workshops. Underground stations are costly and difficult to maintain but save space. They are applied to medical facilities, factories, and large residential complexes.

When choosing the type of transformer station, it is important to clearly understand the classification by voltage and design to meet the specific needs of the system.

Classification of Transformer Stations by Voltage

1. Ultra High Voltage: Ultra high voltage transformer stations with voltages above 500kV are often suitable for large-scale power transmission over long distances, playing an important role in national power systems.
2. High Voltage: With voltage levels of 66kV, 110kV, 220kV, and 500kV, high voltage transformer stations mainly serve in power transmission from power plants to distribution systems.
3. Medium Voltage: Including voltage levels from 6kV to 35kV, these transformer stations primarily distribute power to residential areas and industrial zones.
4. Low Voltage: Low voltage transformer stations, usually at levels 0.4kV and 0.2kV, serve the power needs of households and small businesses.

Classification of Transformer Stations by Design

• Pole-Mounted Station: Suitable for suburban or remote areas where equipment structures are hung on power poles.
• Gantries Station: Designed with transformers and equipment located between two large pillars, commonly used in residential areas and industrial workshops.
• Base Station: Ideal for rural areas and medium and small enterprises, with transformers placed on concrete foundations.
• Enclosed Station: Placed indoors, optimizing safety and aesthetics, suitable for densely populated urban areas.
• Kiosk Station: Featuring a sealed design in a metal cabinet, kiosk transformer stations are widely used in medium voltage electrical systems.
• GIS (Gas Insulated Switchgear) Station: The optimal choice for large cities due to their compact size and operational safety.

Applications and Types of Transformer Stations

• Intermediary Transformer Station: Functions to convert voltages from 110kV to 220kV down to 22kV to 35kV, usually located outdoors due to large power requirements.
• Distribution Transformer Station: Mainly converts from intermediary voltage to low voltage levels of 0.4kV to 0.22kV.
• Applications in Industry: Used in industrial zones and factories to ensure stable and efficient power supply.

New Technology

• Superconducting Transformer Station: Applies superconducting technology, promising improved efficiency and reduced power loss.
• Semiconductor Transformer Station: Although still in the research phase, this technology holds significant potential for changing the way electricity is transmitted.

Factors Affecting the Quotation for a 2000kVA Transformer Station

The quotation for a 2000kVA transformer station depends on various factors such as construction location, fluctuations in material prices, and the specific design of the station. The distance from the station to the medium voltage line affects the materials used. Changes in material prices in the market require investors to consider the timing of construction. Technical specifications and station design also determine the final cost.

1. Project scale and transformer station capacity: A large scale requires a more complex transformer station design, needing more materials and effort.
2. Installation location: The specific location not only affects transportation costs but also requires construction suitable to the terrain.
3. Terrain and infrastructure conditions: Complex terrain or limited infrastructure increases costs due to additional resources and time needed.
4. Technology and equipment: Investing in modern transformer station technology might be initially higher but brings long-term efficiency.
5. Labor costs: Construction bid prices for stations are significantly influenced by labor costs, particularly those of skilled workers.
6. Permit and legal fees: Fees for transformer station permits and other procedures also play a role in the total cost.
7. Brand and origin: From brands like Thibidi, EMC, Mitsubishi to Cadivi, origin and reputation affect material costs.
8. Market and raw material prices: Market price fluctuations can change the cost of necessary transformer station materials.

The 2000kVA transformer station offers technical and economic efficiency in providing stable power. To optimize investment, thoroughly considering the factors affecting the quotation and suitable application is crucial.
