Handling cable for power supply and/or signal transmission

Abstract

A handling cable is provided, which is intended especially for electric power and/or the signal transmission with a travelling mobile machine. The invention is remarkable in that the handling cable comprises at least one sheath made by autoreticulation of a composition comprising thermoplastic polyurethane and a reticulation agent provided with at least two isocyanate functions.

1 . A handling cable intended especially for electric power and/or signal transmission with a travelling mobile machine comprising: 
 at least one sheath made by autoreticulation of a composition containing thermoplastic polyurethane and a reticulation agent provided with at least two isocyanate functions.    
   
   
       2 . The handling cable as claimed in  claim 1 , wherein the reticulation agent is selected from the group including methane diphenyl diisocyanate (MDI) and its derivatives, isophorone diisocyanate (IPDI) and its derivatives, toluene diisocyanate (TDI) and its derivatives, hexamethylene diisocyanate (HDI) and its derivatives, or any mixture of these compounds.  
   
   
       3 . The handling cable as claimed in  claim 1 , wherein the composition of the sheath material includes between 2 and 20 parts by weight of reticulation agent per 100 parts by weight of thermoplastic polyurethane, and preferably between 4 and 10 parts by weight of reticulation agent.  
   
   
       4 . The handling cable as claimed in  claim 3 , wherein the composition of the sheath material is between 4 and 10 parts by weight of reticulation agent per 100 parts by weight of thermoplastic polyurethane.
