Definitions

the invention relates to an electrical power line with a central support element, several stranded around the central support element, each having an electrical conductor and an overlying insulation, and an outer jacket.
Such electrical power lines are, for example, as so-called flexible and reelable lines for the power supply of portable consumers such. B. used for the energy supply of elevators on construction sites.
the electrical power lines are exposed to high mechanical loads. During the winding or unwinding of a reelable power line, considerable upsetting and tensile forces act on the line.
a steel cable as the central supporting element.
such a central steel cable serving as a supporting element can be provided with a rubber covering.
the use of a steel cable as a central supporting element has the disadvantage that the flexibility of the power line is reduced.
the invention is therefore based on the problem of designing an electrical power line having a central support element in such a way that it has a high degree of flexibility and is reliably protected against damage even under high mechanical loads.
the advantages that can be achieved with the invention are, in particular, that a good mechanical contact with a high coefficient of friction between the support element and the energy wires is produced by the external high tensile strength threads of the support element and the braiding of each of the energy wires, so that the energy wires adhere firmly to the support element and the support element significantly for mechanical relief, in particular for strain relief, which contributes to the central support element stranded energy veins.
the central support element and thus the entire cable has a comparatively high flexibility.
the core is made of an ethylene-propylene elastomer such as B. EPDM (ethylene / propylene-diene terpolymer) is formed.
B ethylene-propylene elastomer
EPDM ethylene / propylene-diene terpolymer
the high tensile strength threads applied to the core of the support element are made of aramid, for example of Kevlar. Such threads have a very high resistance to stretching, great strength and flexibility and enable a flexible and high-strength support element.
the high-tensile threads are applied to the core in the form of a braiding.
each energy wire is designed as an open braid.
control line and communication lines arranged in the outer gussets of the stranded energy wires against mechanical damage, in particular due to tensile stress, it is advantageous if the control line and communication line have a braiding.
the flexible electrical power line 1 shown by way of example in the figure has a central support element 3 which has a z. B. from an ethylene-propylene elastomer such as EPDM (ethylene / propylene-diene terpolymer) existing core 5 and 5 applied to this core 5 high tensile threads 7.
the high-tensile threads 7 are, for example, a high elongation resistance and aramid fibers having great strength and flexibility, as are sold under the trade name "Kevlar".
the high tensile threads 7 are applied to the core 5 in the form of wrapping.
energy wires 9 are stranded around the central support element 3.
Each of these energy wires 9 has an electrical conductor 11 and an electrical insulation 13 lying above it, and an outer braid 15, which is formed, for example, as an open braid made of rayon threads. Between the insulation 13 and the braiding 15 of each energy core 9, for example, a thin film 16, for. B. made of polyester, which prevents a possible puncture of braid elements.
the braids 15 of the energy wires 9 and the high-tensile threads 7 applied around the core 5 ensure intimate contact and high adhesion between the central support element 3 and the energy wires 9 stranded around it, in particular in the case of mechanical stress on the power line 1.
Control lines 19 and / or communication lines 21 can be arranged in the outer gussets 17 of the power line 1 formed between the stranded energy wires 9.
a control line 19 is arranged in three outer gussets 17 and a communication line 21 in one outer gusset 17.
Each of the control lines 19 has two twisted to the pair Control cores 23 on a thin film 28 z. B. made of polyester and over it, for example, as an open braid 24 made of z. B. is surrounded by rayon threads.
the communication line 21 has, for example, two communication wires 25 stranded with one another and is likewise enclosed by a thin film 29 made of polyester and above it by a braid 26 made of rayon threads designed as an open braid.
the braids 24 and 26 ensure that the control lines 19 and the communication line 21 are included in the tensile composite formed from the energy wires 9 and the central support element 3.
the foils 28 and 29 form the base for the braids 24 and 26 and prevent any penetration of braid elements
the stranding assembly consisting of support element 3, energy wires 9, control lines 19 and communication line 21 is enclosed by a gusset-filling inner jacket 31.
an outer jacket 33 is provided, in which an open braid 35 z. B. is integrated from rayon threads.
