• While Powell originated the PCR® concept almost 50 years ago, some solutions require a simpler weather-proof answer.  Any of our products can be incorporated into a Shelterform type construction with either a walk-in or non walk-in feature. These are classically used for remote non-manned installations or projects where protection from the elements is needed but environmental control is not critical.

  • Electrical distribution equipment provided in a Shelterform construction is ideal for applications where basic weatherproof construction is desired and ancillary equipment is not involved. Small switchgear assemblies involving only a few circuit breakers can use a Shelterform solution to keep the project cost to a minimum while providing all the needed safety and environmental protection that is required.

  • With a Shelterform design the exterior enclosure is supported using the internal electrical equipment for structural support. The construction is available with a variety of options including non walk-in, walk-in protected aisle, and walk-in common aisle.
    • Non Walk-in: a weatherproof wrap around the equipment
    • Walk-in Protected Aisle: a weatherproof wrap with an aisleway provided running along the front of the equipment
    • Walk-in Common Aisle: a weatherproof wrap with aisleway provided down the center between two line ups of equipment installed facing one another

  • Shelterform provides the easiest and most cost effective method of providing an integrated packaged solution. The walls are typically not insulated but some environmental control can be provided with HVAC.
    Shelterform construction can be designed for power connections from below or power connections from above. Accommodations can be made for interconnection between units and other jobsite needs.
