    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. By completely eliminating oil leakage and fire hazards, it is 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 is a dry-type transformer and how does it differ from an oil-immersed transformer?
    A dry-type transformer uses air or resin as the cooling and insulating medium instead of oil. Unlike oil-immersed transformers, dry-type models eliminate the risk of oil leakage and fire, making them safer and more suitable for indoor or fire-sensitive environments such as hospitals, data centers, and high-rise buildings.
    Q What does F/H-class insulation mean for dry-type transformers?
    F-class insulation is rated for a maximum operating temperature of 155°C, while H-class is rated up to 180°C. Achieving F/H-class insulation through vacuum casting means the transformer can safely and reliably operate under high thermal stress, extending service life and improving performance in demanding environments.
    Q What is the difference between the SCB13 and SCB14 models?
    The SCB13 complies with China's National Energy Efficiency Standard at Level 2, while the SCB14 meets the more stringent Level 1 standard. The SCB14 offers lower no-load losses and higher overall efficiency, making it the preferred choice for projects with strict energy-saving requirements or green building certifications.
    Q Are dry-type transformers suitable for outdoor installation?
    Standard dry-type transformers are primarily designed for indoor use. However, with appropriate enclosures (such as IP23 or higher-rated weatherproof housings), they can be adapted for outdoor or semi-outdoor installations. Always consult the product specifications and local environmental conditions before outdoor deployment.
    Q How does the compact design of dry-type transformers help reduce energy costs?
    Because dry-type transformers can be installed directly at or near the load center — rather than in a remote substation — the length of power cables is significantly reduced. This directly lowers line losses (resistive losses in cables), resulting in measurable energy savings over the lifetime of the installation.
    Q Do dry-type transformers require regular maintenance?
    One of the key advantages of dry-type transformers is their maintenance-free design. Since there is no insulating oil to monitor, test, or replace, ongoing maintenance requirements are minimal. Periodic visual inspections and cleaning of ventilation openings are generally sufficient to ensure long-term reliable operation.
