Definitions

  • the invention is in the field of energy distribution and is concerned with the constructive and material design of a multi-core, plastic-insulated low-voltage power cable in the sense of environmentally compatible reusability.
  • a cable construction in which core insulation, inner sheath and outer sheath are only environmentally compatible for the construction elements ( halogen-free) and recyclable (ie non-cross-linked) plastics are used, with strict attention to good separability (species purity) of the material components.
  • a thermoplastic, differently colored elastomer based on EPDM is used as the wire insulation material for the different wires, while a polyvalent, thermoplastic and halogen-free material based on a copolymer is used for the outer sheath, which is mixed with an inert, mineral
  • the wire insulation material is designed so that it can withstand conductor temperatures of up to 90 ° C in continuous operation, 110 ° C in emergency operation and 250 ° C in the event of a short circuit.
  • conductor temperatures up to 90 ° C in continuous operation, 110 ° C in emergency operation and 250 ° C in the event of a short circuit.
  • attention is also paid to environmentally friendly production methods (eg the smallest possible use of cooling water and electrical energy) and the preservation of economy (DE-2 "electro-technology " - issue 12 - December 17, 1993, pages 24, 26 and 35).
  • the core insulation, the inner and outer sheath consist of the same base material, the inner sheath being formed by a spinning, that the base material is colored black and that the core insulation with are marked with a wire.
  • Color batches e.g. B. with the trade name "Sicolen” from BASF or the trade name “Blau Ral 5015" from Baywitz Kunststoffwerke, DE, can also be added to the base material, so that the wires of the cable can be easily separated by an extruded, colored line (blue, brown, yellow). Alternatively, there is also one light colored printing with different characteristics.
  • a polyethylene stabilized against susceptibility to stress cracking the density of which lies between 0.92 and 0.94 g / cm 3 and the Shore D hardness of which is greater or at least higher can be used as the base material for wire insulation, inner and outer sheaths is equal to 42.
  • a material which is a low-density polyethylene, for example with a small proportion of one
  • Ethylene-vinyl acetate copolymer is modified, on the one hand has the mechanical properties required for the outer sheath and for the strip material forming the inner sheath, and on the other hand it has the electrical properties required for the core insulation and can be counteracted, if necessary, with conventional means Stabilize aging as well as against copper oxidation. With regard to the heat resistance of the wire insulation, it withstands constant temperatures of less than / equal to 70 ° C. on the conductor. If a permanent temperature of at most 90 ° C. is to be mastered, commercially available thermoplastic elastomers based on polypropylene are used as the base material in the context of the invention.
  • a suitable material is, for example, a polypropylene modified with an ethylene-propylene copolymer or terpolymer, that is to say a polyblend with separate phases (DE-Z "rubber + rubber. Plastics, No. 9/86, pages 804, 806; DE-Z "Kautschuk + Kunststoffe, No. 8/86, pages 695/96; DE-Z” Kunststoffe "1989, No. 7, pages 606 to 611). Such thermoplastic elastomers are sold, for example, by Monsanto under the name "Santoprene”.
  • polypropylene reactor blends with an elastomer content> 25% by weight can be used as the basic material, as used for special applications.
  • the needs of the automotive industry have been developed (DE-Z "Kunststoffe", 1992, No. 6, pages 499 to 501).
  • Corresponding materials are sold by the company BASF under the trade name “Novolen” and also by the company Himont, USA.
  • the figure shows a four-wire low-voltage heavy current cable, the sector-shaped conductors 1 consisting of aluminum or copper are each surrounded by an extruded plastic insulation 2.
  • a foil spinning 4 is applied above the stranding formed from the four cores, which in turn is surrounded by the extruded outer jacket 5.
  • the same base material namely a commercially available low-density polyethylene "Lupolen 2012 D" from BASF with a density of 0.919 to 0.924 g / cm ⁇ was used for the wire insulation 2, the film spinning 4 and the outer jacket 5.
  • This base material is colored black with carbon black (which increases the density to about 0.933 to 0.939 g / cm ⁇ ), so that both the core insulation and the covering as well as the outer jacket are black.
  • the individual cores are distinguished from one another in that three cores are provided with an extruded, colored longitudinal line 3, the color pigments blue, brown and yellow being used. Heavy metal-free ink batches were used here.
  • a polypropylene reactor blend with an elastomer content of, for example, 43% ethylene-propylene rubber (EPM) (for example "Novolen”) can also be used for the wire insulation 2, the foil spinning 4 and the outer jacket 5 "2912 HX from BASF) can be used.
  • EPM ethylene-propylene rubber
  • the film used for the production of the inner jacket from the base material colored black by adding carbon black has a wall thickness of 100 to 120 ⁇ m and is expediently applied in a single-layer covering with overlap.
  • an outer sheath based on a filler-compatible olefin homopolymer or olefin copolymer can then be used instead of a previously conventional outer sheath made of PVC.
  • Suitable polymers are, for example, ethylene-vinyl acetate copolymers with a VA content of 10 to 30% and polyethylenes with very low density, so-called ULD-PE (density approx.
  • a flame-retardant filler in the form of an aluminum oxide hydrate or magnesium hydroxide is to be added in each case to this base material in an amount of approximately 30% by weight or approximately 70 parts by weight per 100 parts by weight of the polymeric base material.

Abstract

Dans le but d'améliorer l'écophilie et notamment la recyclabilité d'un câble d'énergie basse tension multiconducteur à isolation plastique, dans lequel l'isolation (2) des conducteurs, le revêtement intérieur (4) et le revêtement extérieur (5) sont constitués d'un plastique non réticulé sans halogène, le même matériau de base de couleur noire est utilisé pour l'isolation des conducteurs, le revêtement intérieur et le revêtement extérieur, tandis que l'isolation des conducteurs est munie d'un marquage, de préférence sous forme d'une rayure longitudinale de couleur (3). Lors d'un processus de recyclage, il n'est donc pas nécessaire de séparer les différents constituants du câble, composés du même matériau plastique.
