Oldcastle Infrastructure, Inc. products

In addition to our high volume line of compression molded products, Highline uses an open mold spray-up process to create fiberglass transformer box pads, three-phase transformer pads, and ground sleeves that are available in many sizes and applications. Our three-phase transformer pads have external ribs molded into all sides for great side-wall and vertical support. They are available in several sizes. Our transformer pads and ground sleeves are constructed of fire-retardant materials and are gel-coated for UV protection.

MacLean Highline manufactures multipurpose fiberglass deferral cabinets that let you install underground electrical cable for interim needs but which can also be used as single phase sectionalizing cabinets. With a rugged fiberglass construction and UV protection, these three phase deferral cabinets are as aesthetically pleasing as they are functional.
