Definitions

  • the invention relates to an overhead line cable for high-voltage overhead lines.
  • corona discharges lead to high-voltage overhead lines not only to significant electrical losses Energy, the so-called corona losses, but in addition, a considerably disruptive arises at the same time Corona noise.
  • corona discharges are characterized by low Air pressure and high humidity favored.
  • Such Corona discharges can generally be found in so-called Standard ropes can hardly prevent which as a bundle ladder a steel core made of a plurality of steel wires and have a multi-layer cable sheath made of lead wires, which are either aluminum wires or wires is made of aluminum alloys.
  • the invention has for its object an overhead line rope to create for overhead power lines, at which Corona discharges are largely avoided and which nevertheless in terms of installation technology and strength Regarding a standard rope or the project requirements with the same or improved transmission performance equivalent.
  • the overhead line rope is marked to solve this problem through a hollow rope with a given rope diameter and a rope sheath made of one or more Line wire layers and one arranged in the hollow rope Cable sleeve support.
  • the invention is based on the Realizing that there is a standard rope or a any overhead line rope with a hollow rope with clearly larger rope diameter can be replaced to the same or even increased transmission power corona discharges to avoid or at least significantly reduce. Because due to the considerably larger rope diameter as it were an electrode with a lower peripheral field strength realized so that corona discharges as well from it resulting loss of performance and noise pollution be reduced at least to a considerable extent.
  • the invention provides that the cable sheath support as a full or hollow support element Cross-section is formed and complete or at least a support for the cable sheath at predetermined intervals forms.
  • the self-employed The cable sheath support is important as it is flexible Pipe with closed or perforated pipe jacket educated.
  • a corrugated pipe is preferably used closed or perforated tubular jacket as a cable jacket support Use whose outside diameter is the inside diameter corresponds to the hollow rope.
  • the transition from the tubular cable sheath support or the corrugated tube for Standard rope takes place in that the separated standard rope is inserted into the cable sheath support until the Lay the complete standard rope the rope jacket support touch and thus a constant diameter of the support structure is ensured.
  • the insertion length depends on the diameter ratio of the cable sheath support inside to the offset standard rope outside and from Weight and damping requirements.
  • the standard rope sections at their in the cable sheath support projecting ends in negative and / or positive sense gradually.
  • the Wire ends of the stepped standard rope layers are not tied, so jump up and touch the inner surface of the tubular cable sheath support. This will optimize Vibration damping for the hollow rope reached.
  • the relining of the hollow rope according to the invention with an as Full rope trained standard rope takes place at the ends of the hollow rope and in those places where according to route planning taking into account the cable sags and the Requirements of rope regulation and retensioning a Clamp must be set.
  • By relining also becomes a critical vibration behavior in the area the support and guy clamps at least damped. It also has relining has no negative impact on the reduction of corona discharges.
  • an overhead line cable for high-voltage overhead lines shown.
  • this overhead line rope it is a hollow rope 1 with a predetermined Rope diameter D and a rope sheath 2 from two wire layers.
  • a cable sheath support 3 arranged in the hollow cable 1 .
  • the lead wires forming the cable sheath 2 4, 5 consist of aluminum wires 4 and stalum wires 5 in a given distribution.
  • the cable sheath support is as flexible Corrugated tube 3 formed, which consists of a Aluminum alloy is made.
  • a Hollow rope end is a Full rope section 6 from z. B.
  • the corrugated tube 3 is in the area of the relining of the hollow rope or its rope sheath 2 through the standard rope section 6 accordingly. Beyond that the standard rope section 6 on its in the corrugated tube 3rd cantilevered end stepped at 7 and up to Contact with the stepped end 8 of the corrugated tube 3 in the hollow rope 1 inserted.
