Open Type with Conservator Transformer

Open Type with Conservator Transformer

   Open type with conservator is an older type of transformer commonly used for a long time. It uses transformer oil as insulation and cooling as same as the hermitically sealed oil type distribution transformer. However, there is a conservator installed to support the expansion of transformer oil during use. The tube allows air to pass out. And at the end of the tube, it contains a silica gel capsule which is a substance to absorb moisture from the air before entering the transformer.  Transformer oil of this type transformer must be checked regularly every 6-12 months.
