- the WO 01/61711 discloses a conduit of the initially mentioned type with a polymer-based shell with inorganic, flame-retardant additives.
- the jacket in this case comprises an outer, an intermediate and an inner layer, wherein the intermediate layer is foamed.
- the WO 01/61711 A1 refers to a generic cable WO 98/52197 A1 whose flame retardance is to be improved.
- the prior art cable already had a layer of a foamed polymeric material having predetermined mechanical strength properties and a predetermined degree of foaming, whereby a high impact strength could be set.
- the present invention has for its object to provide an electrical line of the type mentioned, which has an improved quality in view of the aforementioned mechanical and processing properties.
- the jacket consists of a thermoplastic polyurethane elastomer and comprises an inner, an intermediate and an outer layer, wherein the outer layer and / or the inner layer is a foamed layer, and wherein the intermediate layer is a non-foamed layer , It can be provided in detail that the sheath consists of several sub-layers, of which at least one is foamed.
- a foamed layer which may be in particular a gas-filled closed-cell material, advantageously reduced by the invention, the specific mass of the line, the stripping over large and oversized cable lengths is facilitated, and improve the torsional behavior as well by a damping effect of the foamed layer, the mechanical pressure resistance and bending fatigue strength.
- Thermoplastic polyurethane elastomers are semi-crystalline materials and belong to the class of thermoplastic elastomers. They are high performance materials, which in their characteristic image dynamic load capacity, high flexibility in a wide temperature range, high wear resistance and buckling and breaking strength (tear and tear resistance) with good resistance to the influence of oil, grease and solvents, the weather, ozone and Combine UV radiation, as well as hydrolytic substances and microbes. They are reflowable and can therefore easily be subjected to recycling.
- thermoplastic polyurethanes with blowing agents for the production of shoe soles.
- the hard segments are formed by diisocyanates used in the preparation and short-chain diols, and the soft segments by diisocyanates and long-chain diols.
- a sheathed electrical line consists of at least one electrical conductor 1, which is surrounded by an insulation 2, and a plastic sheath 3.
- electrical conductors 1 are shown with their insulation 2 by way of example ,
- the conductor 1 may consist of an electrically conductive material in the form of strands or in the form of a wire, which may preferably have a diameter in the range of 0.03 mm to 3.0 mm.
- a wire used for the conductor 1 can also be formed from a plurality of individual wires 1 a.
- the insulation 2 of the conductor 1 consists of a thermoplastic elastomer (TPE), in particular styrene-containing TPE, a polyolefin such as polypropylene (PP), an ethylene-vinyl acetate copolymer (EVA) or a fluoropolymer, such as FEP (tetrafluoroethylene-hexafluoropropylene copolymer ).
- TPE thermoplastic elastomer
- PP polypropylene
- EVA ethylene-vinyl acetate copolymer
- FEP tetrafluoroethylene-hexafluoropropylene copolymer
- the jacket 3 comprises a foamed layer 4.
- the jacket 3 consists of a thermoplastic polyurethane (TPU), which may in particular be a polyether polyurethane.
- TPU thermoplastic polyurethane
- the use of a polyester-polyurethane is due to its higher thermal stability possible with advantage.
