A resin cast dry-type transformer is a type of transformer that uses epoxy resin instead of the traditional insulation oil in oil-immersed transformers, which results in higher safety, environmental friendliness, and maintenance convenience. It typically consists of high-voltage coils, low-voltage coils, a core, and a resin cast insulator.
Resin cast dry-type transformers have many advantages over oil-immersed transformers, such as:
1. Higher safety: Due to the absence of insulation oil, resin cast transformers are safer and less prone to accidents such as fires and explosions.
2. Better environmental friendliness: Insulation oil in oil-immersed transformers often contains pollutants, which can cause environmental pollution. The epoxy resin used in resin cast transformers is non-toxic, odorless, and pollution-free.
3. More convenient maintenance: Due to the absence of oil contamination, resin cast transformers are easier to maintain, more durable, and reduce maintenance costs.
4. Higher load capacity: Resin cast transformers have excellent heat dissipation performance, which allows them to withstand higher load capacities and improve operational efficiency.
Due to these advantages, resin cast dry-type transformers have been widely used in power systems.
