Definitions

  • the invention is in the field of electrical cables and wires and deals with the further development of plastic-insulated low-voltage cables.
  • the invention has for its object to provide an insulating mixture for multi-core low-voltage cables with an extruded core insulation based on a radiation-crosslinked polymer, which has good adhesion properties to casting resins, as are common for the production of casting resin sets on 1 kV cables.
  • the components (comonomer, resin, filler) deviating from ethylene or polyethylene eliminate the apolar character of the surface of radiation-crosslinked polyethylene insulation, so that there is excellent adhesion to the casting resins customary for cable fittings, in particular also to such Casting resins such as those used for low-voltage cables with core insulation made of polyvinyl chloride.
  • the comonomer used in the context of the invention is preferably a vinyl acetate.
  • other comonomers such as, for example, ethyl acrylate, vinyl propionate, vinyl butyrate, acrylic acid, acrylic acid ester, methacrylic acid and methacrylic acid ester can also be used.
  • copolymers or terpolymers of ethylene with two or more polar comonomers can also be used.
  • the insulating mixture provided according to the invention can contain further additives as are customary for insulating mixtures, in particular color pigments and stabilizers such as antioxidants and metal deactivators.
  • each of the wires 1 to 4 consists of a solid sector conductor 5 and an extruded plastic insulation 6.
  • the four strands stranded together are surrounded by the inner sheath 7 and the outer sheath 8 made of polyvinyl chloride.
