Structural Features

  • Core Structure: Uses high-quality cold-rolled silicon steel sheets with multi-step lap joints to reduce no-load loss and noise.
  • Winding Structure: High-voltage windings adopt epoxy resin casting, while low-voltage windings adopt foil structure, with good insulation performance and mechanical strength.
  • Shell Design: Uses corrugated steel plate shell, with good heat dissipation performance and protection performance.
  • Insulation System: Uses epoxy resin as insulation material, with good heat resistance and insulation performance.
  • Protection Devices: Equipped with temperature controller, fan control and other protection devices to ensure safe and reliable operation of the transformer.

Performance Advantages

  • High Efficiency and Energy Saving: Both no-load loss and load loss are lower than national standards, meeting energy-saving requirements.
  • Safe and Reliable: Uses epoxy resin casting technology, featuring fire resistance, explosion-proof, and pollution-free characteristics.
  • Low Noise: Through optimized core structure and winding design, operating noise is low.
  • Easy Maintenance: Reasonable structure, simple inspection and maintenance, no need for regular replacement of insulation oil.
  • Long Service Life: Under normal operating conditions, the service life can reach more than 20 years.
  • Good Environmental Performance: No transformer oil is used, no pollution to the environment.

Application Scenarios

  • High-rise buildings
  • Commercial centers
  • Hospitals
  • Subways
  • Airports
  • Data centers
  • Factory workshops
  • Schools

Maintenance

  • Regular Inspection: Regularly check the operating status of the transformer, including parameters such as temperature and noise.
  • Cleaning Maintenance: Regularly clean the transformer surface and heat sinks to ensure good heat dissipation.
  • Insulation Testing: Regularly conduct insulation resistance testing to ensure good insulation performance.
  • Fan Maintenance: For air-cooled transformers, regularly check the fan operating status to ensure its normal operation.
  • Temperature Controller Inspection: Regularly check the working status of the temperature controller to ensure its normal operation.

Safety Precautions

  • The transformer should be installed in a well-ventilated, dry place without corrosive gases.
  • Avoid overload operation when the transformer is running.
  • Regularly check the grounding device to ensure good grounding.
  • Strictly follow operating procedures when operating the transformer.
  • When abnormal conditions occur in the transformer, immediately stop operation and conduct maintenance.
  • Regularly check protection devices to ensure their normal operation.
