Various 5KVA single-phase transformers available, practically never used.

5 KVA Single-Phase Transformers, Virtually Never Used

1. Product Description

5 KVA single-phase transformers are essential equipment for voltage conversion in single-phase systems. These transformers, while used, are virtually unused, meaning they offer excellent performance at a significantly lower cost than new ones. They are ideal for industrial and commercial applications requiring reliable and precise power conversion.

2. Materials and Components

• Insulation: Oil or resin (depending on the model), chosen for its excellent insulation properties and heat dissipation capabilities.
• Core: Made of silicon steel sheet to reduce energy losses and improve efficiency.
• Windings: Made of high quality copper to ensure low resistance and high conductivity.
• Construction: Rugged and durable construction, designed to last and withstand harsh operating conditions.

3. Dimensions and Weight

• Rated Power: 5 KVA
• Voltage: Variable, typically 230V or 120V (depending on project specifications).
• Weight: Approximately 30-50kg (approximate, may vary depending on specific configuration).
• Size: Approx. 0.5 x 0.5 x 0.5 meters (approximate, may vary depending on specific configuration).

4. Mechanical Characteristics

• Efficiency: High, thanks to the quality of the materials and the advanced design that reduces energy losses.
• Thermal Stability: Good, with adequate heat dissipation capacity to maintain operational stability.
• Insulation: Excellent, with materials that protect the transformer from contamination and humidity.

5. Usage Procedure

1. Installation: Place the transformer in a well-ventilated and easily accessible area. Ensure there is sufficient space for cooling and maintenance.
2. Connection: Connect the input and output cables according to the voltage specifications and safety regulations.
3. Power on: After connecting, turn on the transformer and monitor operating parameters such as voltage and current.
4. Monitoring: Regularly check the temperature and operation of the transformer to ensure optimal operation.

6. Matching accessories

• Monitoring Devices: Temperature and Voltage Sensors.
• Warning Systems: Alarms for malfunctions or abnormal conditions.
• Protections: Circuit breakers and fuses to ensure operational safety.

7. Mathematical formulas

• Apparent Power: S=V×IS = V \times I $$S$$ $$=$$ $$V$$ $$\times$$ $$I$$ Where VV $V$ is the voltage and II $I$ is the current.
• Efficiency: Efficiency = Output Power Input Power × 100% \text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} \times 100 \% $$\text{Efficiency}$$ $$=$$ Input Power Output Power ​× $$100\%$$
• Core Losses: Measurable by eddy current analysis and hysteresis losses.

8. Materials He Can Work with

• Resistive Loads: Suitable for powering devices and equipment that require constant power.
• Inductive Loads: Compatible with motors and secondary transformers.
• Capacitive Loads: Compatible, but check specifications for highly capacitive loads.

9. Maintenance

• Insulation Inspection: Regularly check the condition of insulation materials and check for signs of contamination or deterioration.
• Temperature Control: Monitor operating temperatures and maintain levels within specified limits.
• Cleaning: Keep the area around the transformer clean and well-ventilated. Periodically check the seals and connections.

10. Used Goods Check

• General Condition: Ensure there are no signs of physical damage or wear. Check for oil leaks (if applicable) and check the condition of the windings.
• Operation Tests: Test the transformer to ensure that all operating functions are stable and correct.
• Documentation: Check maintenance documentation and certifications to confirm transformer quality and specifications.

11. Sectors of Use

• Industry: For applications requiring voltage conversion in industrial environments.
• Commercial: Used in shops and offices to power equipment and machinery.
• Residential: Suitable for homes requiring low power transformers.

12. Advantages of Buying Used

• Lower Cost: Buying a used transformer like this can work out significantly cheaper than buying a new one.
• Quality Guaranteed: Being practically never used, the transformer offers performance comparable to that of a new one.
• Immediate Availability: Used transformers are often available for immediate purchase and installation, reducing waiting times and associated costs.

In summary, the virtually unused 5 KVA single-phase transformers are an excellent choice for those seeking a reliable, high-quality transformer at a reasonable price. With proper maintenance and careful inspection, these transformers can provide excellent performance for many years. If you have any further questions or require further details, I'm here to help!
