300 kVA Dry Type Transformer | Industrial-Grade Efficiency & Safety | QIANLAI ELECTRIC
As the founder of QIANLAI ELECTRIC, a professional transformer manufacturer with years of industrial experience, I’m proud to present our flagship 300 kVA dry type transformer—a reliable power solution engineered for stability, safety, and long-term value. Unlike oil-immersed transformers, our dry type design eliminates fire hazards and environmental risks, making it the ideal choice for high-demand indoor and industrial environments. Whether for manufacturing plants, data centers, or commercial buildings, this transformer delivers consistent performance to keep your operations running smoothly.
Why Choose QIANLAI’s 300 kVA Dry Type Transformer?
At QIANLAI ELECTRIC, we prioritize quality from raw material selection to final testing. Our 300 kVA dry type transformer stands out from competitors with core advantages rooted in our factory’s precision engineering and strict quality control.
Superior Safety & Environmental Compliance
Adopting epoxy resin encapsulation and self-extinguishing insulation materials, our 300 kVA dry type transformer is non-flammable, explosion-proof, and free of toxic fluids. It operates without leakage or pollution, meeting international environmental standards and fire safety regulations for enclosed spaces like shopping malls, hospitals, and data centers. You can trust it to work safely even in high-temperature or dusty industrial conditions.
High Efficiency & Low Operational Costs
We use imported cold-rolled silicon steel sheets for the core and high-temperature polyester enameled copper wires for windings, combined with vacuum pressure impregnation (VPI) technology. This ensures an efficiency rating of ≥98%, minimizing energy loss and reducing your electricity bills. The dry air cooling system requires no regular oil changes or complex maintenance, cutting long-term operational costs by up to 30% compared to traditional transformers.
Stable Performance & Durability
Our 300 kVA dry type transformer is designed to handle voltage fluctuations (±10% input voltage adjustment) and continuous heavy loads, with a withstand voltage of 3000V and insulation resistance ≥50MΩ. It operates quietly (noise level ≤60dB) and maintains stable output even in harsh environments with humidity, salt fog, or dust. Each unit undergoes strict short-circuit and temperature cycle tests to ensure a service life of over 20 years.
Flexible Customization & Global Certification
We understand that every project has unique needs. QIANLAI’s300 kVA dry type transformer supports customization of input/output voltage (380V/400V/480V, etc.), phase configuration (single/three-phase), protection class (IP21 to IP54), and cooling method (natural air or forced air cooling). All products comply with IEC, IEEE, and GB standards, holding CE, ISO, and UL certifications to meet global market requirements.
