Product Description

• Oil-Free Design: The dry-type transformer stands out with its remarkable feature of not requiring an oil tank or insulating oil, utilizing air or an insulating gas for insulation and cooling. This innovative design ensures superior fire prevention and explosion safety, ideal for environments demanding high levels of fire safety and densely populated areas like high-rise buildings, underground facilities, hospitals, and schools.
• Winding Structure: Featuring windings that undergo epoxy resin casting or vacuum pressure impregnation, this advanced treatment provides the windings with robust mechanical and electrical integrity. This design guards against moisture absorption, deformation, and insulation aging, thereby significantly boosting the reliability and longevity of the transformer.

  Performance Features

• Good Fire-Resistance: The absence of oil completely eliminates risks of leakage or combustion, thereby drastically minimizing fire hazards. This meets the stringent fire protection criteria required by modern architecture and industrial electrical installations.
• Excellent Heat Dissipation: Dry-type transformers utilize natural air cooling (AN) or forced air cooling (AF) for efficient heat dissipation. Natural cooling relies on air convection to disperse heat, whereas forced cooling uses fans to enhance airflow, accelerating heat elimination and ensuring long-term, stable operation at rated capacity.
• High Insulation Performance: The adoption of cutting-edge insulating materials, such as glass fiber-reinforced epoxy resin, provides exceptional electrical insulation. These materials are capable of withstanding high voltage, effectively preventing insulation failure.
• Strong Short-Circuit Withstanding Capability: Thanks to its compact winding structure and formidable mechanical resilience, the transformer withstands substantial short-circuit currents without deformation or damage, enhancing its short-circuit resistance and mitigating equipment damage and outages caused by such faults.

Environmental Features

• Pollution-Free: The absence of insulating oil translates to zero risk of leakage or environmental contamination, which makes it a green, environmentally-friendly solution adhering to ecological standards.
• Low Noise: Operating at a low noise level, typically around 50-60 decibels, it ensures minimal disturbance to the surrounding environment and personnel, making it ideal for settings with stringent noise regulations.

Maintenance Features

• Maintenance-Free or Low-Maintenance: Its straightforward dry-type structure eliminates the need for oil-related maintenance. Routine upkeep is minimal, focusing on basic cleaning, inspections, and securing tasks, thereby cutting maintenance costs and efforts.
• Easy Installation: Designed for convenience, the compact size and lightweight nature of dry-type transformers facilitate easy installation. They can be flexibly positioned to accommodate available space without the extensive area required for oil tanks in oil-immersed models.
