5 KVA Single Phase Transformers, Practically Never Used

1. Product Description

5 KVA single phase transformers are essential equipment for voltage conversion in single phase systems. These transformers, while used, have virtually never been used, which means they offer excellent performance at a significantly reduced cost compared to new. They are ideal for industrial and commercial applications requiring reliable and precise power conversion.

2. Materials and Components

• Insulation: Oil or resin (depending on model), chosen for its excellent insulation properties and heat dissipation ability.
• 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: Robust and durable construction, designed to last over time and to withstand harsh operating conditions.

3. Dimensions and Weight

• Rated Power: 5 KVA
• Voltage: Variable, typically 230 V or 120 V (depending on design specifications).
• Weight: Approximately 30-50kg (approximate, may vary depending on specific configuration).
• Dimensions: Approximately 0.5 x 0.5 x 0.5 meters (approximate, may vary based 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. Make sure there is sufficient space for cooling and maintenance.
2. Connection: Connect the input and output cables respecting the voltage specifications and safety regulations.
3. Power On: After connecting, turn on the transformer and monitor the 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: Sensors for temperature and voltage.
• Alert Systems: Alarms for malfunctions or anomalous conditions.
• Protections: Protection switches 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 PowerInput Power×100%\text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} \times 100 \% $$\text{Efficiency}$$ $$=$$ Input Power Input Power Output × $$100\%$$
• Core Losses: Measurable through eddy current and hysteresis loss analysis.

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. Verification of Good Used

• General Condition: Make sure 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 operational functions are stable and correct.
• Documentation: Check maintenance documentation and certifications to confirm the quality and specifications of the transformer.

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: Purchasing a used transformer like this can be significantly cheaper than purchasing a new one.
• Guaranteed Quality: Having practically never been 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, 5 KVA single-phase transformers, which are practically never used, are an excellent choice for those looking for a reliable, high-quality transformer at a low price. With good maintenance and careful checking of the condition, these transformers can offer excellent performance for many years.
