  • Patent number: 5683203
    Abstract: A method and apparatus for installing a padmount transformer using a buried support frame is provided wherein the transformer is mounted adjacent a trench about the underground cable, the frame includes a pair of telescopically extendable legs which rest on the trench bottom. Each of those legs reaches to the top of the trench and is removably attached at that upper end to one of a pair of arms that rest on the surface of the ground under where the floater pad is to be placed. A stabilizing bar is removably attached to each of the legs to secure them in a desired relative position. The position of each of these frame elements can be adjusted to permit the top of the frame to be made level. The relatively compact ground at the bottom of the trench and the surface adjacent the trench secures the frame against significant or uneven changes in vertical position over time.

  • Patent number: 5623122
    Abstract: A breakaway connection device is provided which is particularly suited for use with residential electric service cables. This device is mounted between the service cable and the service pole and serves to disconnect the cable from the pole upon the application of a predetermined level of tension or force to the cable. That level of force is selected so that the service cable breaks away from the pole and de-energizes the conductive wires before the service cable would pull away from and damage the dwelling. This device includes an insulated sheath having therein two hollow wire receiving elements which are separably joined by a conductive insert, formed as a solid rod or threaded member.
