SG(B)10, SG(B)11 non-encapsulated dry type transformer
- Dustproof and damp-proof: the appearance is coated with special waterproof materials to form a dustproof, damp-proof and anti-pollution special protective layer.
- Small size and light weight: DuPont NOMEX paper is taken as the main insulating material, the volume and weight can be reduced by 20% compared with epoxy casting type transformer in same capacity.
- Strong cooling capacity: multi-layer cylindrical, longitudinal multi-air-channel structure, better in cooling effect compared with epoxy casting transformer
- Environment protection: Reliable, free of combustion-supporting resin, non-toxic, able to be decomposed and recycled, and pollution-free
- Especially applicable to the areas with high temperature, humidity and dirt in China such as hydropower plant, thermal power plant, steel works, chemical engineering and mine.

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.
