What is the standard enclosure type for HPS EV charging transformers and what are the optional ones?

The standard enclosure for HPS EV charging distribution transformers is a Type 3R enclosure, with an optional Type 3RE plus available.

Type 3R Enclosure: This general-purpose, ventilated enclosure is suitable for indoor or outdoor use. It provides protection for personnel against access to hazardous parts and protects the equipment inside from solid foreign objects (such as falling dirt). It also safeguards against water ingress (rain, sleet, snow) and remains undamaged by ice formation on the exterior.

Type 3RE Plus Enclosure: This is also a general-purpose, ventilated enclosure for indoor or outdoor use. It offers all the protections of the Type 3R enclosure, with additional protection against circulating dust and snow, ensuring greater resilience in harsh environmental conditions.
