Abstract

A trefoil cable arrangement that secures cables during a short circuit event. The trefoil cable arrangement has a top cleat and a bottom cleat. The bottom cleat is secured to the top cleat to form the trefoil cable arrangement. The top cleat has an outer surface, an inner surface, and ends with mounting holes. The bottom cleat has an outer surface, an inner surface defining a cable support area, and ends with mounting holes. The cable support area is curved to support various sized cables.

First claim

1 . A trefoil cable arrangement for securing cables during a short circuit event, the trefoil cable arrangement comprising:
a top cleat having an outer surface, an inner surface, and ends with mounting holes; and a bottom cleat having an outer surface, an inner surface defining a cable support area, and ends with mounting holes, wherein the cable support area is curved to support cables having a range of radius; whereby the bottom cleat is secured to the top cleat to form the trefoil cable arrangement.

2 . The trefoil cable arrangement of claim 1 , wherein the top cleat and the bottom cleat flare outwards for providing space to enable the cables to expand during a short circuit event.

3 . The trefoil cable arrangement of claim 1 , wherein the bottom cleat has recessed pockets for housing fasteners and reducing a height of the trefoil cable arrangement.

4 . The trefoil cable arrangement of claim 1 , wherein the outer surface of the bottom cleat has recessed ends for enabling the bottom cleat to be positioned on a ladder rung.

5 . The trefoil cable arrangement of claim 1 , wherein the outer surface of the bottom cleat having hex pockets for facilitating the installation of fasteners in the mounting holes.

6 . The trefoil cable arrangement of claim 1 , wherein the outer surface of the top cleat and the outer surface of the bottom cleat have strengthening ribs; and the inner surface of the top cleat and the inner surface of the bottom cleat have gripping ribs for engaging cables.

7 . The trefoil cable arrangement of claim 1 , wherein the bottom cleat further comprising a middle mounting hole and a recessed pocket surrounding the middle mounting hole; and wherein the trefoil cable arrangement is secured to cables and a ladder rung by positioning end fasteners in mounting holes in the ends of the bottom cleat; attaching the bottom of the cleat to the ladder rung by a fastener positioned through the middle mounting hole in the bottom cleat; positioning cables on the bottom cleat; positioning the top cleat over the cables; and positioning the end fasteners through the mounting holes at the ends of the top cleat.

8 . The trefoil cable arrangement of claim 1 , wherein the trefoil cable arrangement is secured to cables and a ladder rung by installing end fasteners through holes in a ladder rung and mounting holes in the ends of the bottom cleat; positioning cables on the bottom cleat; positioning the top cleat over the cables; and positioning the end fasteners through the mounting holes at the ends of the top cleat.

9 . The trefoil cable arrangement of claim 1 , wherein each end of the top cleat includes a raised member for reinforcing the ends of the top cable cleat.
