  "title": "Apparatus for retaining electrical cables",
  "abstract": "A cable retaining apparatus includes a body defining at least one aperture for receiving a respective cable, a first insulator device arranged in the, or each, aperture for preventing electrical conduction from a cable to a surface of the body facing the cable, and a second insulator device for preventing electrical conduction from a cable to a surface of the body facing away from the cable.",
  "claims": [
    "1. A support apparatus configured for supporting a cable retaining apparatus, the cable retaining apparatus including a body defining at least one aperture for receiving a respective cable, wherein the support apparatus comprises: a carriage portion configured to be mounted to the cable retaining apparatus; and a track portion configured to be mounted to a support, wherein the track portion includes a plurality of curved apertures for receiving a fastening device for mounting the track portion to the support, such that the carriage portion is slidably mounted to the track portion and the apertures enable pivoting of the track portion relative to the fastening device when the support apparatus is in use while supporting a cable retaining apparatus having at least one cable supported in the cable retaining apparatus.",
    "2. An apparatus according to claim 1, further comprising a stop device for limiting a range of sliding movement of the carriage portion relative to the track portion.",
    "3. An apparatus according to claim 1, further comprising a fastening device for fastening the track portion to the support.",
    "4. A support apparatus according to claim 3, wherein the fastening device includes at least one respective bolt configured to engage the, or each, aperture.",
    "5. A support apparatus according to claim 4, further comprising a restraining device for preventing rotation of the, or each, bolt relative to the track portion.",
    "6. A support apparatus according to claim 5, wherein the restraining device includes at least one connecting member for connecting respective heads of a plurality of the bolts."

  "description_excerpt": "The present disclosure relates to an apparatus for retaining electrical cables and relates particularly, but not exclusively, to an apparatus for retaining high-voltage cables in a separated trefoil configuration. The present disclosure also relates to a mounting device for mounting the apparatus to a surface and to an insert suitable for use with the apparatus.\n\nA cable cleat is a device for securing one or more electrical cables to a surface. The surface may be oriented at any angle. Some types of cable cleat secure a plurality of cables together. Cable cleats are installed at intervals along a length of the one or more cables to provide sufficient anchoring to the surface and to provide sufficient restraint when there is a plurality of cables being held together, for reasons described in detail below.\n\nWhen a plurality of electrical cables is laid in proximity to one another, current passing through the cables creates electromechanical forces which act on the cables. Especially large electromechanical forces are generated in the event of an electrical connection being made between two or more of the cables, such as during a short circuit. These forces can cause the cables to violently repel each other, which can be dangerous to personnel located near the cables. Cable cleats are used to retain cables in position in the event of such an occurrence.\n\nCable cleats hold electrical cables tightly together. This increases the magnitude of the electromechanical forces experienced by the cables due to increased proximity and leads to a more violent reaction of the cables to a short circuit.",
