Fully Integrated Tunnel (FIT) & Mating Side (MS) Box Pads

Concast's FIT & MS box pads are specifically designed to support 3-phase transformers for the wind industry.  This style of box features a larger space for the cables as they leave the base of the wind turbine and enter the box. 

The FIT or Fully Integrated Tunnel Fibercrete® Box Pads have the transformer opening rotated 90 degrees from the integrated tunnel opening.  The MS or Mating Side box mates directly against the turbine base and has a radiused face for a clean fit. 

These boxes provide a more direct path for below-grade cable to travel from the turbine footings to the transformer than a standard box pad, so they will ensure improved cable integrity. At time of order Concast must receive your transformer footprint drawing to ensure proper size and opening location.
