Definitions
- the invention relates to a cable head of a high-current multiple cable for DC applications, in which the ends of a plurality of individual strands existing cable ropes in to the axis of a covered by an outer tube cylindrical portion of a cable lug concentrically extending bores inserted and by radial compression while deforming the holes in these are fixed in position, with a central cooling water channel in the middle of the cable lug and connected to the cooling water channel on the circumferential side of the cylindrical section Cooling water grooves are provided.
- Such a cable head is known from DE 23 41 900 C3.
- the ends of the cable-receiving holes on a single pitch circle.
- a large bending radius leads thus inevitably to a larger space requirement for the high-current multiple cable.
- the invention is based on the object of a Cable head of a high-current multiple cable for DC applications create, which is small in volume and therefore cheaper installation options of a high-current multiple cable allowed.
- the invention thus provides a distribution of the bores and thus the ends the cable ropes over the entire cross section of the cylindrical portion of the cable lug in front. Because of this distribution, the diameter of the cable head in the Compared to the prior art can be kept smaller. By the in diameter smaller cable head is also a smaller diameter of the outer tube realizable. Hence the use of a cable head designed in this way leads equipped high-current multiple cable e.g. when planning a new or Conversion of a DC furnace to significant space savings due to the then smaller bending radius. It follows that the length of the cables is reduced can be.
- both the reduction in the outer tube diameter leads as well as the smaller cable head in addition to a weight reduction.
- FIG. 1 is the cable head of a high-current multiple cable 2 for DC applications designated.
- the cable head 1 comprises a cable lug 3 made of copper or the like, which with a cylindrical section 4 is fixed in position in an outer tube 5.
- the over the end face 6 of the outer tube 5 protruding tongue-like part 7 of the cable lug 3 is used to connect to a conductor or consumer.
- the cable lug 3 is traversed centrally by a cooling water channel 8, which on Free end 9 of the cable lug 3 has transversely directed connections 10. On the inside At the end 11 of the cable lug 3 there is a choke 12 as a transition to one the cooling pipe 13 passing through the high-current multiple cable 2.
- Cooling water grooves 18 Extend between the holes 15 lying on the outer pitch circle TK approximately V-shaped from the outer peripheral surface 17 of the cylindrical portion 4 Cooling water grooves 18 with a depth T close to that on the inside Pitch circle TK1 lying holes 16.
- the groove bases 19 are rounded.
- the Cooling water grooves 18 run from the end face 14 of the cylindrical section 4 over a length that is slightly longer than the length of the holes 15, 16. Die inner ends of the cooling water grooves 18 are via inclined channels 20 with the in the central cooling water channel 8 extending the axis 21 of the cable lug 2.
- the bores 15, 16 serve to receive and fix the ends 22 from a variety of individual strands 23 existing cable ropes 24.
- the definition of Ends 22 in the bores 15, 16 are carried out, as can be seen in FIG. 3, by a radial compression (P) of the material of the cylindrical section 4 and the ends 22.
- P radial compression
- the ends 22 lying on the outer pitch circle TK of the circumferential surface 17 radially pressed, while that on the inner pitch circle TK1 lying ends 22 are radially pressed from the groove bases 19.
