Dry type cast resin, epoxy resin cast transformer, epoxy resin dry type transformer and so on all belong to the dry type transformer, then have you ever produced the question, why is it called dry type transformer?
The reason why dry type transformer is called 'dry type', the core lies in its work completely 'no oil soak'. This is like our mobile phones, some mobile phones even if not soaked in water also has a waterproof function, dry-type transformer is the same, it abandoned the traditional liquid (such as oil) to achieve heat dissipation and insulation, but rely on the 'dry' method to complete the work.
Dry-type transformers do not use any liquid media, and all of their structure is made up of 'dry' solid materials, such as copper wires, epoxy resin, silicon steel sheets, etc. This is similar to the way we use electricity in our homes. It's like an electric fan in our house, with only metal and plastic inside, and no water or oil present. In addition, dry-type transformers eliminate a series of hidden dangers caused by oil. Oil-immersed transformers may appear 'oil fire' situation, and dry-type transformers can withstand a maximum of 180 ° C high temperature, once more than this temperature, it will automatically cut off the power, to protect the safety; at the same time, there will be no 'oil leakage' of the problem, which for the Some special places, such as hospital operating theatres and food factories, where the presence of oil is absolutely prohibited.
From a deeper perspective, dry-type transformers in the name of 'dry', in fact, is a declaration of the technical route. Oil-immersed transformers, the name with 'oil', obviously emphasises the dependence on oil, while dry-type transformers, the name goes "oil", declaring that it gets rid of the dependence on liquids, which is the same as the "electric car " emphasises the fact that it does not use oil is a reason.
