Abstract

Abstract The support system for electrical cables includes a plurality of orthogonally disposed support rails and standardized clamping joints for adjustably clamping the rails together. Cable supporting beams may be disposed in spaced, parallel relation to selected rails and standardized clamping joints are provided at opposite ends of the cable supporting beams for adjustably connecting beams to a rail and clamping a plurality of cables therebetween. All of the beams, rails and joints are of insulating material.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 226 words
A support system for electrical cables in high voltage equipment comprising a plurality of support beams of insulating material disposed at right angles to each other to define at least one intersection point, first clamping means of insulating material engaging said support beams at each intersecting point to adjustably secure said beams relative to each other and second clamping means of insulating material adapted to clamp at least one cable to one of said beams wherein each support beam is comprised of two parallel spaced apart strips of material and the first clamping means is comprised of a first rectilinear block of insulating material having a first pair of parallel spaced apart grooves in one surface thereof receiving said two strips constituting a first beam and a second pair of parallel spaced apart grooves in the opposite surface of said block disposed at right angles to said first pair of grooves receiving the two strips constituting a second beam at right angles to said first beam and two second blocks of insulating material each having a pair of parallel spaced apart grooves in one surface thereof receiving the two parallel strips of a first beam and a second beam respectively with said second blocks being aligned with said first blocks and insulating securing means for clamping said blocks and said beams together at said intersecting point.
Claim 2
Dependent Claim 226 words
A support system for electrical cables in high voltage equipment comprising a plurality of support beams of insulating material disposed at right angles to each other to define at least one intersection point, first clamping means of insulating material engaging said support beams at each intersecting point to adjustably secure said beams relative to each other and second clamping means of insulating material adapted to clamp at least one cable to one of said beams wherein each support beam is comprised of two parallel spaced apart strips of material and the first clamping means is comprised of a first rectilinear block of insulating material having a first pair of parallel spaced apart grooves in one surface thereof receiving said two strips constituting a first beam and a second pair of parallel spaced apart grooves in the opposite surface of said block disposed at right angles to said first pair of grooves receiving the two strips constituting a second beam at right angles to said first beam and two second blocks of insulating material each having a pair of parallel spaced apart grooves in one surface thereof receiving the two parallel strips of a first beam and a second beam respectively with said second blocks being aligned with said first blocks and insulating securing means for clamping said blocks and said beams together at said intersecting point.
Claim 3
Dependent Claim 21 words
