📝 Product Description
Transformer View 1
Transformer View 2

The SC(B) series epoxy resin cast dry transformer is manufactured using advanced vacuum casting technology with thin insulating bands. The core utilizes high-permeable grain-orientated silicon sheets, ensuring superior performance and efficiency.

  • 1
    Mechanical Strength: The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin, providing excellent mechanical properties and eliminating cracks or inner bubbles.
  • 2
    Reliability: Features low local discharge and a long service life, designed for high-performance industrial applications.
  • 3
    Environmental Resistance: High and low voltage systems are cast under vacuum to prevent moisture absorption. Core clamps are treated for corrosion resistance, allowing operation in high temperatures or harsh environments.

❓ Frequently Asked Questions
What is a cast resin dry-type transformer?
It is a type of transformer where the magnetic circuit and windings are not immersed in insulating oil, but are instead cast in an epoxy resin mixture under vacuum.
What are the main advantages of epoxy resin insulation?
It provides high mechanical strength, is flame-retardant, moisture-proof, and requires minimal maintenance compared to oil-filled units.
Can these transformers be used in high-humidity areas?
Yes, because the coils are cast under vacuum, they do not absorb moisture, making them ideal for humid or heavily polluted environments.
What cooling method is used for these transformers?
The standard cooling is ONAN (Oil Natural Air Natural, or in this dry context, Air Natural). Forced air cooling (AF) can also be used to increase capacity.
Are custom voltages available for the secondary winding?
Yes, while 400V is standard, we can provide customized secondary voltage levels based on specific project requirements.
What international standards do your transformers meet?
Our products are manufactured in accordance with the IEC60076 standard and hold ISO9001 and CCC certifications.
