Abstract:
A power cable heating arrangement (100) is disclosed, comprising a first electric heating element (101) adapted to generate heat in at least a portion (102) of a conductor (103) of a first power cable (104) on a condition that an electrical current is supplied to the first electric heating element (101). A second electric heating element (105) is adapted to generate heat in a predefined portion (106) of a conductor (107) of a second power cable (108) on a condition that an electrical current is supplied to the second electric heating element (105). At least one temperature sensor (110) is arranged in relation to the second power cable (108) so as to be able to sense a temperature of the predefined portion of the conductor of the second power cable. An electrical current source (112) is coupled to the at least one temperature sensor (110) and the first and second electric heating elements (101, 105), respectively. The electrical current source (112) is adapted to supply an electrical current to the first electric heating element (101) and to the second electric heating element (105), respectively. On a condition that there is a difference between the sensed temperature of the predefined portion (106) of the conductor (107) of the second power cable (108) and a predefined temperature, the electrical current source (112) is adapted to, based on the difference, adjust the electrical current being supplied to the first electric heating element (101) and to the second electric heating element (105), respectively.
Abstract:
The present invention relates to a device for machining an electrical cable having a cylindrical part and a conical part adjoining the cylindrical part. The device comprising a fixture (10) arranged to receive the cable and to hold the cable in a fixed position, the fixture defines an elongated space (15) for accommodating the cable, a tool (17) for removing material from the cable including at least one cutter (22), and rotational guiding means (25) for guiding a first rotation of the cutter about a longitudinal axis of said space. The cutter is elongated and the longitudinal axis of the cutter is arranged inclined with respect to the longitudinal axis of said space so that the angle between the longitudinal axes of the cutter and the space is between 10 and 80 degrees. The device further comprises drive means (24) for providing a second rotation of the cutter about a rotational axis through the tool in order to cause the machining, and the cutter is adapted to be in contact with the surface of the conical part of the cable as well as the transition between the cylindrical part and the conical part during the machining.
