MPS has designed its J6865 and J6866 one-piece triple transformer racks to make installation easier by making them lighter. These one-piece transformer racks can be assembled with transformers on the ground and then hoisted as a unit into position for mounting on the pole. The transformer racks include a welded lifting eye to facilitate hoisting the rack up onto the pole.
The J6865 rack has 12" lug centers for mounting three, 3kVA through 50kVA transformers. The J6865 has a strength capacity of 2000 per position or a total of 6000 lbs for all three positions loaded simultaneously. Six 5/8" x 1-3/4" machine bolts are included for bolting the transformer to the rack. It is recommended the rack be fastened to the pole with two 3/4" machine bolts and two 1/2" lag screws to prevent the installation from wobbling in the wind (sold separately). Holes are provided for a groundwire lug.
The J6866 rack can be used to mount three transformers ranging from 75kVA through 333kVA (24" mounting hole spacing). The J6866 has a strength capacity of 5,000 lbs per individual position or a total of 15,000 for all three positions loaded simultaneously. Each position is designed to accommodate ANSI type "B" lug spacing. Six 3/4" x 2-3/4" machine bolts are included for bolting the transformer to the rack. It is recommended the rack be fastened to the pole with two 3/4" machine bolts and four 1/2" lag screws (sold separately). Holes are provided on the rack for a groundwire lug.
The TB series cast transformer mounts feature a locking slot for a 3/4" diameter pole mounting bolt. The mounts can be installed on the transformer prior to installation of the assembly on the pole. They are furnished with two 5/8" diameter bolts, nuts and washers for attachment to the transformer. Accommodates maximum 4000 lbs. transformer weight.
J6865 and J6866 are RUS approved.
