CEEG has developed transformers designed to excel in high-altitude, extreme temperatures, and other harsh conditions. Our transformers are engineered to operate in environments with ambient temperatures up to 50°C, achieving a 55K average winding temperature rise, a 50K top oil temperature rise, and resistance to mild seismic activity. To date, our transformers have been successfully deployed at altitudes as high as 3,800 meters.
Case Study: 20MW Solar-Storage Power Station in Zhada, Tibet
In the thin air and challenging environment of Zhada County, Tibet, at an altitude of 3,800 meters, CEEG supplied a for a 20MW photovoltaic energy storage power station. This area experiences low temperatures, low atmospheric pressure, strong winds, and frequent sandstorms and thunderstorms, demanding exceptional transformer design and craftsmanship. To address these challenges,we tailored the transformer design to:
Adapt to high-altitude conditions by increasing air clearances to account for reduced insulation strength.
Use meticulously selected materials for the components, ensuring durability and reliability.
Increase the size of the dry-type transformer to accommodate the demands of the high-altitude environment.
A customized transportation plan was also devised to ensure the safe delivery of the equipment to the remote site.
Innovations for Extreme Weather and Ultra-High Voltage
To meet the growing demands of ultra-high voltage transmission and withstand extreme weather events, CEEG has developed a 10,000kVA/35kV high-voltage, large-capacity dry-type transformer featuring advanced insulation materials, including:
Creep-resistant coatings to prevent surface discharge.
Low-temperature-resistant and flame-retardant resins for enhanced safety and reliability.
These transformers effectively mitigate the risk of electrical creeping, forming a robust defense for power grids. They ensure safe, stable operation even under the harshest climate conditions, contributing to the resilience and reliability of modern energy systems.
