• Surge Arrester: Protects the station from lightning and overvoltage events.
• Capacitor Banks and Inductors: Used to adjust voltage and current, keeping the system stable.

3. Secondary Equipment

Includes equipment for safe operation and system monitoring:

• Relay Protection Devices: Protect the station from short circuits and overloads.
• Measurement and Monitoring Devices: Include current transformers and measurement transformers, monitoring operating parameters.
• Automation Devices: Modern control systems ensure the ability to automatically handle faults.

4. Electrical Cables

Electrical cables play a role in transmitting and distributing electricity from the transformer station:

• Medium Voltage Cables: Used to transmit electricity from the source, e.g., 22KV, 24KV cables.
• Low Voltage Cables: Distribute electricity to end-use consumers, such as 600V CV120mm² cables.

5. Transformer Station Accessories

Accessories support and protect the system:

• Insulators and Supports: Lift insulators and transformers.
• Connectors and Cable Clamps: Ensure connection and safety of cables.
• Earthing System: Extremely important for electrical safety.
• Electrical Cabinets: MCCB and meter cabinets for system management and control.

6. Construction Materials

Ensure infrastructure for the transformer station:

• station base: It needs to be solid to bear the weight of the transformer.
• Protective Fence: Prevents unauthorized entry, can use wire mesh or build walls.

7. Safety Equipment

Necessary measures to protect the station:

• Spread Surge Protection: Protects against impacts from overvoltage.
• Protection Fuses: Prevents short circuits and overloads.

Maintenance and installation design must comply with technical and electrical safety standards. This is the key to efficient and safe operation of the transformer station system.

Factors Affecting the Price of a 160kVA Transformer Station

The origin and quality of materials are crucial in pricing. Installation location significantly affects transportation and construction costs. Station types such as steel poles, platforms, or kios also impact total investment costs.

Determining the price of a 160kVA transformer station is a complex task, influenced by many technical and practical factors. To accurately assess costs, it is necessary to consider factors from the voltage system, type of transformer, to transformer station design and specific installation requirements.

Voltage System

• Power grid voltage: Ensuring compatibility with the current grid voltage is a vital requirement, affecting the type of equipment and general construction costs.
• Wiring Type: Wiring types like Dyn or Yzn will determine the price due to differences in equipment and construction methods.

Type of Transformer

• Oil transformers and dry transformers have significant price differences. Specifically, oil transformers with or without ancillary oil tanks will have considerably different prices. The determined capacity of 160kVA is a primary factor affecting initial investment costs.

Design and Station Type

• Platform transformer station: With concrete pole design, it is suitable for open spaces, usually lower cost.
• Kiosk station: Closed block design with high aesthetic value, higher cost due to safety and good design requirements.
• Steel pole compound station: Suitable for limited space, cost is near equivalent to kiosk stations.

Materials and Switching Equipment

• Using medium and low voltage cables (such as underground or overhead cables) has different costs, depending on material and length.
• Medium and low voltage switching equipment (FCO, LB, and MCCB) also impacts price due to their technology and performance.

Installation Location

• Geographic space: Locations such as residential or industrial areas can greatly affect aesthetics and safety requirements.
• Topographical conditions: Costs may increase due to site preparation or specific terrain processing.

Technical and Legal Requirements
