20KV Cast Resin Dry-Type Power Transformer
Flame-retardant, maintenance-free solution for modern infrastructure
The 20kV Cast Resin Dry-Type Power Transformer is designed for applications requiring enhanced fire safety, low maintenance, and compact installation. Ideal for commercial buildings, hospitals, data centers, and renewable energy systems, this transformer eliminates the risks of oil leakage and fire hazards associated with traditional oil-immersed units.
🔑 Key Features
Rated Voltage: 20kV – Suitable for high-voltage distribution in medium-voltage networks.
Cast Resin Technology – Fully encapsulated windings offer superior insulation and moisture resistance.
No Oil, No Risk – Fire-retardant and explosion-proof, making it safe for indoor environments.
Low Noise & Vibration – Epoxy resin encapsulation reduces operating noise and mechanical stress.
Zero Maintenance – No oil refills, leak checks, or fire suppression systems required.
Eco-Friendly – 100% recyclable material, compliant with green building requirements.
