  • Method for producing electrical cables coated with cross-linked polyethylene
    Patent number: 6830777
    Abstract: In a method for producing electrical cables coated with cross-linked polyethylene, a polyethylene granulate is mixed with a liquid silane-containing cross-linking agent, the granulate thus prepared is melted in an extruder and extruded onto the electrical cable, and the extruded coating is cross-linked in the presence of water or steam. A mixture of granular material of a polyethylene homopolymer and a polyethylene copolymer is coated with the cross-linking agent. The copolymer content in the coating on the cable is between 1 and 8% by weight.
    Type: Grant
    Filed: July 24, 2001
    Date of Patent: December 14, 2004
    Assignee: Nexans
    Inventors: Franz Danekas, Marc Strittmatter
  • Process for the production of conducting wires coated with cross-linked polyethylene
    Patent number: 6645411
    Abstract: In a process for the production of conducting wires coated with cross-linked polyethylene in which a granulate made of polyethylene is coated with a fluid cross-linking agent, the coated granulate is melted in an extruder and extruded onto the electrical conducting wire, and the extruded film is cross-linked by being heated to a temperature over the decomposition temperature of the cross-linking agent, a mixture of granulate, meal, or powder made of a polyethylene homopolymer and a polyethylene copolymer is coated with the cross-linking agent and stabilizer, with the portion of copolymer in the coating on the cable lying between 1 and 8 weight percent.
