Partner with reliable suppliers to benefit from reliable, low-maintenance solutions that enhance your power distribution systems

    The product employs high-purity copper coils wound into robust insulators formed through vacuum casting, delivering exceptional moisture-proof, dust-proof, and flame-retardant performance (typically achieving F/H-class insulation). This ensures reliable long-term operation in harsh environments.

    💧

    Moisture-Proof

    Advanced vacuum casting technology ensures complete protection against moisture ingress, even in high-humidity environments.

    🛡️

    Dust-Proof

    Sealed insulator construction prevents dust accumulation, maintaining performance integrity over extended service life.

    🔥

    Flame-Retardant

    F/H-class insulation rating with inherent flame-retardant properties — no oil leakage, no fire hazard.

    🏢

    By completely eliminating oil leakage and fire hazards, dry-type transformers are particularly suitable for fire safety-critical locations such as high-rise buildings, rail transit systems, data centers, hospitals, commercial complexes, and industrial/mining enterprises.

    Frequently Asked Questions
    Q What makes dry-type transformers safer than oil-immersed transformers?
    Dry-type transformers completely eliminate the use of insulating oil, which removes the risks of oil leakage and fire hazards. Their flame-retardant resin insulation and F/H-class insulation rating make them inherently safer, especially in fire-sensitive environments such as hospitals, data centers, and high-rise buildings.
    Q What is the difference between SCB13 and SCB14 models?
    The SCB13 meets China's National Energy Efficiency Standard at Level 2, while the SCB14 achieves the higher Level 1 standard. The SCB14 offers superior energy-saving performance with lower no-load losses, making it the ideal choice for projects with strict energy efficiency requirements.
    Q In which environments are dry-type transformers most suitable?
    Dry-type transformers are ideal for environments where fire safety, cleanliness, and reliability are critical. Typical applications include high-rise buildings, rail transit systems, data centers, hospitals, commercial complexes, and industrial or mining enterprises. Their moisture-proof and dust-proof design also makes them suitable for humid or dusty conditions.
    Q Do dry-type transformers require regular maintenance?
    One of the key advantages of dry-type transformers is their maintenance-free design. Unlike oil-immersed units, there is no insulating oil to monitor, test, or replace. Routine inspections are still recommended, but the overall maintenance burden is significantly lower, resulting in reduced lifecycle costs.
    Q How does vacuum casting improve transformer performance?
    Vacuum casting technology ensures that the high-purity copper coils are fully encapsulated in resin without voids or air gaps. This process enhances the insulation's mechanical strength, moisture resistance, and thermal stability — resulting in a longer service life and more reliable operation under harsh environmental conditions.
    Q Can dry-type transformers be installed directly at the load center?
    Yes. Thanks to their compact structure, absence of flammable oil, and flexible installation requirements, dry-type transformers can be installed directly at or near the load center. This significantly reduces the length of low-voltage cables, minimizes line losses, and improves overall system efficiency.
