Definitions

  • the invention is in the field of energy distribution and deals with the constructive and material technology Design of a multi-core, plastic-insulated low-voltage power cable in the sense of an environmentally friendly Recyclability.
  • a cable construction is known in which for the core insulation, inner jacket and outer jacket construction elements only environmentally compatible (i.e. halogen free) and recyclable (i.e. uncrosslinked) plastics are used, being strict on good separability (species purity) of the material components is respected.
  • So is used as wire insulation material for the different wires a thermoplastic, different colored EPDM-based elastomer used, while for the outer jacket a polyvalent, thermoplastic and halogen-free material based on a copolymer is used with an inert, mineral Flame retardant is filled.
  • the core insulation material is like this designed to have conductor temperatures of up to 90 ° C in Continuous operation, from 110 ° C in emergency operation and from 250 ° C in the event of a short circuit withstands.
  • manufacture of this cable also on environmentally friendly production methods (e.g. the smallest possible Use of cooling water and electrical energy) and preservation of economic viability (DE-Z "electrical engineering” - Issue 12 - Dec 17, 1993, pages 24, 26 and 35).
  • the core insulation, the inner and outer jacket made of the same base material exist, the inner jacket formed by a braid is that the base material is colored black and that provide the core insulation with a core identification are.
  • a polyethylene stabilized against susceptibility to stress cracking the density of which lies between 0.92 and 0.94 g / cm 3 and whose Shore D hardness is greater than or at least equal to 42 can be used as the base material for wire insulation, inner and outer sheath .
  • Such a material which is a low-density polyethylene modified, for example, with a small proportion of an ethylene-vinyl acetate copolymer, has on the one hand the mechanical properties required for the outer jacket and for the strip material forming the inner jacket, and on the other hand the electrical properties required for the wire insulation and can be stabilized with conventional means against aging as well as against copper oxidation.
  • thermoplastic elastomers based on polypropylene are used as the base material in the context of the invention. Such materials can also be stabilized against aging as well as against copper oxidation using conventional means.
  • 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.
  • 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 base material, as they have been developed for special needs of the automotive industry (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 power cable, the sector-shaped, aluminum or copper conductor 1 are each surrounded by an extruded plastic insulation 2.
  • a film covering 4 is applied over the stranding structure 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 3, was used for the wire insulation 2, the film spinning 4 and the outer jacket 5.
  • This base material is colored black by means of carbon black (which increases the density to about 0.933 to 0.939 g / cm 3 ), so that both the wire 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.
  • the film spinning 4 and the outer jacket 5 also a polypropylene reactor blend with a Elastomer content of, for example, 43% ethylene-propylene rubber (EPM) (e.g. "Novolen” 2912 HX from BASF) is used become.
  • EPM ethylene-propylene rubber
  • the film used for the production of the inner jacket the base material colored black by adding soot has a wall thickness of 100 to 120 microns and is useful in single-layer covering with overlap applied.
  • 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 about 30% by weight (or from about 70 parts by weight to 100 parts by weight of the polymeric base material).
  • Chalk is expediently added as an additional filler in an amount of 25% by weight (or 50 parts by weight to 100 parts by weight of the polymeric base material).
  • nonpolar copolymers mentioned are sold, for example, by Dow Chemical, USA under the name “Engage” polymers and by Exxon, USA under the name “Exxpol”.
  • Exxpol Exxpol
