Impregnated Dry-Type Transformer
Product Features:
Safety: The transformer is inherently fire-retardant, exhibiting excellent flame resistance, pollution-free operation, and superior corrosion resistance. These characteristics enable direct installation at load centers without compromising safety or environmental performance.
Moisture Resistance: Designed for reliable and stable operation under 100% relative humidity, ensuring consistent performance in high-moisture environments.
Maintenance-Free Operation: Features simple installation and minimal maintenance requirements, contributing to low total cost of ownership over the equipment lifecycle.
Outstanding Performance: Delivers low no-load and load losses, minimal partial discharge, reduced noise emissions, high mechanical strength, strong short-circuit withstand capability, and efficient heat dissipation, ensuring optimal operational efficiency and reliability.
Temperature Control and Protection: Integrated with a comprehensive temperature monitoring and protection system to guarantee safe and stable transformer operation. Field operational data from deployed units confirm that the product’s reliability indicators meet internationally advanced standards.
Application Scope:
This product is widely applicable in power transmission and distribution systems, including hotels, commercial buildings, high-rise structures, shopping centers, stadiums, petrochemical facilities, subway systems, railway stations, airports, and offshore drilling platforms. It is particularly well suited for load centers and installations where stringent fire safety and environmental requirements are mandated.
Operating Conditions:
- Altitude: Not exceeding 1,000 meters above sea level.
- Ambient Temperature:
- Maximum ambient temperature: +40°C
- Maximum daily average ambient temperature: +30°C
- Maximum annual average ambient temperature: +20°C
- Minimum ambient temperature: –30°C (for outdoor units)
- Minimum ambient temperature: –5°C (for indoor units)
- Supply Voltage Waveform:
The supply voltage waveform should closely approximate a sinusoidal waveform to ensure proper operation.
- Polyphase Voltage Symmetry:
For polyphase transformers, the applied supply voltages should be nearly symmetrical to maintain balanced loading and prevent thermal or mechanical stress.
