What is an electrical substation?
Designed for commercial and industrial applications, unit substations are composed of one or more transformers combined with one or more switchgear or switchboard configurations to convert distribution voltages to utilization voltages. They are available in single-phase or three-phase, and can be used indoors or outdoors, with dry-type unit substations being the most popular choice for outdoor use.
The main function of a unit substation is to locate the transformer closest to the highest concentration of power, thus reducing the chance of faults and improving efficiency. However not all unit substations are created equal, and just like other transformers and electrical supply hardware, there are different types specifically designed for different applications.
Choosing your electrical unit substation.
Whether low voltage or medium voltage, electrical unit substations use a variety of mechanisms to get the job done. VPE transformer coils are silicone-treated to withstand the most common outdoor conditions (rain, wind, etc.), while VPI transformer coils are treated with a high temperature polyester varnish to withstand common indoor industrial conditions like moisture, dirt and dust. Cast coil transformers, however, are designed to meet extremely high electrical demands to withstand even the most extreme of conditions, and are most commonly used in the heaviest of industrial applications.
