>> Product Introduction

The epoxy-resin cast dry-type transformer offers a safe, high-performance solution for modern power distribution. Fully encapsulated in heat-resistant epoxy compound, it delivers superior dielectric strength, inherent fire retardancy (certified to IEC 60076-11), and excellent moisture protection. The oil-free design completely eliminates explosion hazards, making it particularly suitable for indoor environments such as office towers, healthcare facilities, and mission-critical data centers.

Engineered for quiet operation with noise levels below 65dB and peak efficiencies approaching 99%, this transformer significantly cuts system losses. Its virtually maintenance-free solid construction guarantees dependable service even under adverse conditions. Available with ratings up to 35kV and both AN (natural) and AF (forced) cooling options, the design accommodates tailored solutions for industrial plants, renewable energy projects, and infrastructure developments.

1. Superior Fire Safety
Epoxy encapsulation provides self-extinguishing properties with zero fire propagation risk, fully compliant with IEC 60076-11 flame-retardant requirements.

2. High Efficiency & Low Loss
Achieves up to 99% operational efficiency with minimized no-load and load losses, translating to lower electricity costs over the transformer's lifespan.

3. Silent Operation
Acoustic performance kept under 65dB, suitable for noise-sensitive settings like hospitals, schools, and residential complexes.

4. Robust & Maintenance-Free
Solid cast resin insulation resists moisture, dust, and contaminants, requiring no routine oil testing or fluid replacement throughout its service life.

5. Versatile Configurations
Supports voltage ratings up to 35kV and optional forced-air cooling (AF) for enhanced overload capacity, adaptable to diverse project specifications.

>> Product Advantage

1.Flame-Retardant & Explosion-Proof Design

Our epoxy-resin dry-type transformers meet IEC 60076-11 standards with self-extinguishing properties (oxygen index >40%). The 100% oil-free construction eliminates fire hazards, making them ideal for high-risk areas like chemical plants and underground mines.

2.High-Temperature Resistance (H-Class Insulation)

Featuring 180°C-rated insulation, our transformers outperform standard F-class (155°C) units with 20% longer lifespan. The glass-fiber reinforced epoxy encapsulation withstands thermal shocks, ensuring stable operation in -40°C to +50°C environments.

3.Ultra-Low Energy Loss (Up to 99% Efficiency)

Advanced amorphous core technology reduces no-load losses by 30% compared to conventional models (SCB13: ≤0.33W/kg). Achieves Energy Efficiency Level 1 certification.

4.Smart Monitoring Ready (IoT Integration)

Equipped with built-in PT100 sensors and RS485 interface for real-time monitoring of temperature, load, and harmonics. Our TX-3000 cloud platform enables predictive maintenance, reducing downtime by 40%.

>> Product Uses

1.Commercial Complexes & High-Rise Buildings

Ideal for shopping malls and office towers due to compact size and fire safety (meets NFPA 70 standards). The 55dB low-noise operation ensures quiet environments, while H-class insulation supports 24/7 air-conditioning loads.

2.Mission-Critical Facilities

Essential for hospitals (ICU power backup), data centers (Tier III/IV), and airports where 99.99% uptime is required. Our transformers' <0.5% failure rate ensures uninterrupted operation.

3.Industrial Manufacturing

Withstands harsh factory conditions - dust (IP54), humidity (95% RH), and chemical corrosion. Special harmonic-resistant design protects CNC machines in automotive plants.

4.Renewable Energy Systems

Wind/solar farms benefit from its -40°C cold-start capability and 150% temporary overload capacity.

5.Transportation Infrastructure

Vibration-resistant design perfect for subway traction power (EN 45545 fire rating) and EV charging stations.

>> FAQ

How does epoxy-resin insulation improve safety?

The epoxy encapsulation provides flame-retardant (Class F1 fire rating), self-extinguishing properties, and eliminates oil leakage risks. It meets IEC 60076-11 standards with 100% partial discharge-free performance.
What maintenance is required?

Virtually maintenance-free - no oil testing or filter replacements needed. Just annual thermal imaging checks (included in warranty) to ensure optimal performance.
What's the lifespan?

30+ years with H-class insulation (180°C). Field data shows 92% of units exceed 25 years in commercial buildings with proper ventilation.
