Leading power and automation technology group, ABB delivered six Resibloc dry-type transformers rated at 5,860 kVA at the Daocheng-Yading airport in the Sichuan Province of China. ABB’s transformers will facilitate the distribution of power to the airport.
When the airport opens later this year, travellers will land and depart at an elevation of 4,411 metres, 77 metres higher than the current record held by the Bamda airport. With a 4,200m runway and four tarmacs, the airport is expected to handle around 500,000 passengers each year.
Built at ABB’s production facility in Shanghai, the Resibloc distribution transformers are specially designed to withstand challenging environmental conditions such as extreme temperatures and very high altitudes. More than 60,000 ABB Resibloc dry transformers are in operation in demanding applications around the world.
Markus Heimbach, head of ABB’s Transformers business, a part of the company’s Power Products division explains that the robust oil-free transformers are safe, reliable, cost-efficient and environment-friendly with the strength to withstand thermal and mechanical stresses from severe climates, cyclical loads, and short circuit forces.
Dry-type transformers are frequently used in applications where contamination and fire risks for people and the environment must be mitigated. They are designed to meet stringent electrical parameters, have the ability to cope with tough ambient conditions and require minimal maintenance, making them a preferred option for sectors such as oil and gas, marine, mining, steel, paper and chemical industries, in commercial and high-rise buildings as well as in power generation and distribution.
Key features of ABB Resibloc dry transformers:
- Made of pure epoxy resin reinforced with glass fibre rovings
- Can withstand extreme mechanical stress and thermal shock
- Explosion resistant
- Designed to operate in a temperature range of -60°C to +50°C
- Flexible design with windings customisable to fit customer specifications
