Problems solved by technology

The efficiency of natural air cooling is low, and it cannot be effectively applied to dry-type transformers under continuous working conditions, while forced air cooling requires sufficient power input, and driving the fan for cooling through electric power not only consumes more electric energy, but also lasts for a long time. Working for a long time will easily cause overheating damage to the fan, thereby reducing the environmental protection of the dry-type transformer, which does not conform to the current concept of high efficiency, low carbon, and green environmental protection
