High-Security Cable

Abstract

A high-security cable is provided, wherein the high-security cable is capable of achieving a smoothing of a work-to-break energy curve. The high-security cable is manufactured of a mixture of plastic yarns or of plastic yarns and metal wires, wherein the cable comprises a first constituent part of untwisted or twisted yarns, or untwisted or twisted yarns and metal wires, a second constituent part of doubled yarn, the doubled yarn manufactured of plastic yarns or of plastic yarns and metal wires, and a third constituent part of cord manufactured from the doubled yarns, wherein the doubled yarn is manufactured from plastic yarns or of plastic yarns and metal wires. The high-security cable can be used as a safety arrester cable, and can also be used to form a netting to serve as safety arrester netting or falling-rock protection netting.

1 . A high-security cable which is manufactured of a mixture of plastic yarns or of plastic yarns and metal wires, the cable comprising:
 a first constituent part of untwisted or twisted yarns, or untwisted or twisted yarns and metal wires,   a second constituent part of doubled yarn, the doubled yarn manufactured of plastic yarns or of plastic yarns and metal wires, and   a third constituent part of cord manufactured from the doubled yarns, wherein the doubled yarn is manufactured from plastic yarns or of plastic yarns and metal wires.   
   
   
       2 . The high-security cable according to  claim 1 , wherein each plastic yarn sort is present in each constituent part. 
   
   
       3 . The high-security cable according to  claim 1 , wherein each metal wire sort, if present, is present in each constituent part. 
   
   
       4 . The high-security cable according to  claim 1 , wherein the cable comprises at least one yarn of fibres of the group of carbon fibres, p-aramide fibres, m-aramide fibres and PBO fibres. 
   
   
       5 . The high-security cable according to  claim 1 , wherein the cable comprises wires of nickel or of an austenitic Ni—Cr alloy. 
   
   
       6 . The high-security cable according to  claim 1 , wherein the doubled yarns are manufactured of in each case an equally large share of S-twisted yarns and Z-twisted yarns. 
   
   
       7 . The high-security cable according to  claim 4 , wherein the share of yarns with a tensile strength of above 10 cN/dtex are mainly present in the first and the second constituent part. 
   
   
       8 . The high-security cable according to  claim 4 , wherein the yarns have a twisting of a minimum of 30 twists per meter and a maximum of 600 twists per meter. 
   
   
       9 . The high-security cable according to  claim 1 , wherein the metal wires are integrated in the yarn with the cover-spinning method. 
   
   
       10 . The high-security cable according to  claim 1 , wherein the cable comprises a safety arrester cable configured to connect a wheel of a racing car to its chassis. 
   
   
       11 . The high-security cable according to  claim 1 , wherein the cable comprises a plurality of windings of loops closed in parallel, such that at least one open tab is formed in each case at both ends of the cable. 
   
   
       12 . The high-security cable according to  claim 1 , wherein the cable comprises a netting. 
   
   
       13 . The high-security cable according to  claim 12 , wherein the netting comprises a safety arrester netting along ski slopes. 
   
   
       14 . The high-security cable according to  claim 12 , wherein the netting comprises an avalanche arrester netting. 
   
   
       15 . The high-security cable according to  claim 12 , wherein the netting comprises a falling-rock protection netting.
