SG (B) 10 and SG (B) 11 non-encapsulated dry type transformer
-
Level H insulation: the insulation endurance class of dry type transformer includes F, H and C. The product takes the DuPont NOMEX paper as the main insulating material, the insulation grade is up to H, and the insulation grade of key part is up to C.
Safety: all insulating materials of the product are not combustion-supporting, self-extinguishing and non-toxic, and there is hardly poisonous smoke after burning under 800℃ for a long time;
Reliability: excellent three-proofs performance (damp-proof, anti-poison and salt-spray proof), able to undertake heat shock and free of crack.
Environment protection: no environmental pollution during manufacturing, transportation, storage and operation, and able to be decomposed or recycled after the service life is expired.
Strong overload capacity: strong overload capacity, fast cooling, and work safely and reliably under 130% overload for a long time.
-
The product is widely applied to power transmission and transformation system, hotel, rAreas with high fire prevention requirement, large load fluctuation, frequent overload operation and densely-populated areas, especially the high-rise buildings, airports, stations, wharfs, metros, hospitals, power generation plants, metallurgy industry, shopping mall, densely-populated and petrochemical industry, nuclear power plants and military project, and the areas with high environmental protection requirements such as water source and reservoir.

Conditions of Use -
Altitude: ≤1,000m; -25℃≤ambient temperature≤40℃, indoor type. Keep well-ventilated for the transformer with air self-cooling and forced air cooling type. When the transformer is installed in basement or other environments with poor ventilation condition, increase cooling and ventilation device. Protection grade: IP00, IP20 and IP23.
-
When the altitude is＞1,000m or the ambient temperature is higher than 40℃ or lower than -25℃, adjust the rated value of product according to the requirements of GB1094.11 Power transformers-Part 11: Dry-type transformers.
