Definitions

  • This invention regards a device for fastening cables and other elongated objects to a base, e.g. in the form of a cable ay.
  • a cable fastener especially adapted for fastening of three single-core cables, where the cables must be anchored in such a manner as to maintain their ability to function during and after the possible passage of a short-circuit current through the cables.
  • Single-core cables of the type in question are provided with an electrically insulating material surrounding an electrically conductive metal core.
  • a fastening element usually in the form of clamps, must be formed so as to ensure that during a short circuit, the electrically insulating material of the cable is not subjected to mechanical forces of a magnitude that might damage the material.
  • clamps of this type where the supporting structure is constituted by a metallic material, to be provided with an elastic material in the form of a binding or intermediate layer designed to be arranged between the clamped cables and the metal supporting section of the clamp.
  • the binding or intermediate layer is designed to prevent the forces arising between the clamp and the cables during a short circuit from damaging the electrically insulating material of the cables.
  • the object of the invention is to remedy the disadvantages of prior art.
  • the clamp according to the invention is provided with a relatively large edge radius along the side portions that extend transversely of the cable.
  • the edge radius is obtained through giving the sheet metal a flange/fold along said side portions.
  • the edge radius of the side portion causes a favourable distribution of the forces between the clamp and the cable, to ensure that the electrically insulating material of the cable is not overloaded during a short circuit.
  • the electrical insulating material of the cables will remain intact, allowing the normal operating voltage to be applied after the short circuit failure has been corrected.
  • the cross sectional opening of the clamp in the longitudinal direction of the cables is shaped so as to support the cables
  • the clamp is also formed in such a way as to simplify the installation work to the greatest possible extent.
  • Figure 1 shows a cable clamp in the closed working position with three parallel single-core cables arranged in the clamp
  • Figure 2 shows the cable clamp in the open non-working state prior to placing the cables in the cable clamp
  • Figure 3 shows a section I-I in figure 1;
  • Figure 4 shows the cable clamp used to fix a large cable or bundle of cables.
  • reference number 1 denotes a cable clamp comprising a fixed clamping portion 2 hereinafter called a bow, and a hinge plate 4 rotatably connected to the bow 2.
  • the bow 2 is provided with a fixing bolt 6 arranged so as to connect the bow 2 to a base (not shown) in the form of e.g. a cableway.
  • the hinge plate 4 is connected to the bow 2 by means of a hinge 8, while at the opposite end, it is provided with through bores 10 corresponding to similar through bores 12 in the bow 2.
  • the cross sections of the bow 2 and the hinge plate 4, see figure 3, are shaped as a folded plate structure in which the central portion 17 of the cross section abuts the cable 16, and where the flanges (folds) 18 are formed in a way such that the side portions of the cable clamp 1 exhibit a relatively large, convex outside radius 20.
  • the cross sectional opening of the cable clamp 1 relative to the longitudinal direction of the cable 16 will in the working position form a triangle with truncated corners.
  • the cross sectional shape will allow three cables 16 of a suitable diameter to be secured in an advantageous manner, see figure 1, or a cable or bundle of cables 22 having a larger diameter to be secured in the clamp, see figure 4.
  • the cable clamp 1 When the cables 16 are to be installed, the cable clamp 1 is coupled to the base (not shown) by means of the fixing bolt 6.
  • the cables 16 are arranged in the cable clamp 1, whereupon the hinge plate 4 is closed by using the fastening bolts 14.
