This epoxy resin dry type transformer is a 250kVA 3 phase dry type transformer designed for high-reliability power systems. Built with fully sealed epoxy resin casting technology (cast resin dry type transformer), it eliminates oil contamination and leakage risks. The epoxy resin material provides excellent heat resistance, moisture protection, and corrosion resistance, ensuring stable operation in harsh environments.
As a three-phase power converter, it efficiently distributes electricity for industrial production lines, data centers, and commercial buildings, meeting global grid standards with customizable voltage settings. Certified by ISO, SGS, and CE, this eco-friendly design reduces long-term maintenance costs while guaranteeing safety and energy efficiency.

(1) Cast Resin Dry-Type Design
The epoxy resin casting technology forms a dense insulating layer, effectively preventing air and moisture penetration. This significantly enhances moisture-proofing, dust-proofing, and flame-retardant properties, reaching a fire-resistance rating of F-class (155°C). It complies with environmental protection and fire safety standards.

(2) High Efficiency of 3 Phase Dry Type Transformers
As a 3 phase dry type transformer, the three-phase balanced design ensures uniform current distribution and reduces energy loss. The high thermal conductivity of epoxy resin enables efficient heat dissipation, ensuring stable temperature rise during full-load operation, achieving an efficiency of over 98% according to SCB10 standards.

(3) Core Advantages of Epoxy Resin Dry Type Transformers

Insulation & Safety: The insulation layer formed by epoxy resin curing is arc-resistant and short-circuit proof, eliminating leakage risks and making it suitable for densely populated or flammable environments.

Mechanical Strength & Longevity: After curing, the epoxy resin forms a high-strength framework that resists impact and vibration, reducing the probability of damage during transportation and installation. It has a lifespan of up to 30 years.

Environmental Friendliness & Low Maintenance: The oil-free design prevents pollution and eliminates the need for regular oil changes or filtration, reducing operational costs and environmental risks.

(4) Wide Temperature Range Adaptability
The epoxy resin material can withstand temperatures ranging from -40°C to 120°C, making it suitable for extremely cold or tropical climates. This ensures stable power supply in various regions around the world.
