Resin Cast Control Transformer

Transformers are electric equipment that changes the voltage and the current of electricity to facilitate its efficient transmission and distribution. Transformers are commonly used at power generation facilities to increase voltage and to decrease current in order to transport electric energy across transmission lines. When the electricity reaches the end user, transformers are used to reduce voltage and to increase current to make the electricity suitable for general use. The process of transforming voltage results in energy loss that is released in the form of heat and therefore transformers must contain effective cooling systems. Transformers are differentiated by their cooling systems (this is one of several ways that the transformer industry classifies its products). Dry type transformers dissipate heat directly into the ambient air. Liquid cooled transformers (e.g. oil filled transformers) dissipate heat into liquid mediums.
