  • Q What are the maintenance guidelines for oil-filled transformers?

    A Maintenance notes for both oil-filled transformers and try type transformers include:
    1. Listen for unusual sounds: Regularly check for any abnormal noises during operation.
    2. Ensure the machine is off: Prior to maintenance, ensure the transformer is powered down and isolated from the electrical supply.
    3. Perform a visual inspection: Examine the transformer for signs of leaks, corrosion, or damage.
    4. Clean the transformer: Keep the transformer exterior and surrounding area clean to prevent dust buildup.
    5. Tighten loose bolts and hardware: Periodically check and tighten any loose bolts or hardware to maintain structural integrity.
    6. Run tests: Conduct routine tests to ensure the transformer is functioning correctly and within specified parameters.
     
    The following maintenance steps are required specifically for oil transformations:
    l Check oil levels: Regularly monitor oil levels and ensure they are within the recommended range.
    l Change filters: Replace oil filters as needed to maintain oil cleanliness and system efficiency.

  • Q What causes a dry type transformer to overheat?

    A Several factors can cause overheating, including improper load rating selection, inadequate airflow, poor insulation, and low-quality windings. To prevent this, it's crucial to select a transformer with a rating suitable for the intended application, install a dry-type unit in a location with sufficient airflow and ventilation, and choose a unit with excellent insulation and high-quality windings.
  • Q Why my dry type transformer makes loud humming noises?

    A If you notice an unusual humming noise from your transformer, it could be due to overloading, aging, loose components, or poor design. To minimize noise and ensure long-lasting operation, it's crucial to select a dry-type transformer with high-quality insulation, superior coiling, excellent construction, and overall good quality.
  • Q Why you need to contact us to customize dry-type transformers used in altitudes above 1000 meters?

    A Dry-type transformers operating above 1000 meters need to be derated due to the diminished cooling capacity of the less dense air. The transformer's capacity should be reduced by 0.3% for every 100 meters above 1000 meters.
  • Q Can 60Hz transformers be used at 50Hz?

    A Transformers with a capacity of 1KVA or more, designed for 60Hz, should not be operated at 50Hz because they will experience increased losses and heat rise. However, a transformer rated for 50Hz can be used on a 60Hz service.
  • Q How to select the right transformers?

    A 1. Transformer Capacity
    Determine the maximum power the transformer needs to provide. Incorrect capacity can lead to overloading or inefficiency. Calculate the required capacity based on your load profile and energy demands.
     
    2. Transformer Size
    l For a single-phase transformer, use the formula:
    V×I/1000. For example, 150×50/1000=7.5kVA
    l For a three-phase transformer, use the formula: V×I×1.732/1000.
    Contact us to ensure the transformer fits your needs before placing the order.
     
    3. Voltage Levels
    Ensure the voltage levels are compatible with your existing energy distribution system.
     
    4. Frequency
    Match the transformer's rated frequency with your system frequency.
     
    5. Location
    Some models are purpose-built to handle moisture and humidity, some are flame and explosion proof, while others boast extra protection against the corrosion near the ocean.
    Indoor transformers must fit in your space. Adequate space for installation is necessary to avoid issues like receiving equipment that doesn’t fit through the door.
     
    6. Compliance and Regulatory Standards
    Ensure the transformer meets industry and national compliance for reliability, safety, and durability.
     
    7. Energy Efficiency
    Opt for transformers with low energy losses and high-efficiency classes to manage operating costs effectively and reduce environmental impact.
     
  • Q Why is transformer selection important?

    A Efficient and cost-effective transformer selection is crucial for industrial, commercial, residence, and utility operations. Downtime can be costly, so a reliable energy source is essential. While cheaper transformers may seem economical initially, investing in a high-quality, reliable transformer saves money over time by ensuring consistent performance and reducing losses.
  • Q What are your accepted terms of international trade?
