Embodiment Construction

[0100] refer to figure 1 There is shown and described a device 1 in the form of a hydraulic cutting device 2 for severing a strand-shaped article 3 to be cut, in particular a strand portion 4, and a power cable as shown 5. In the following case with reference to the power cable 5 , the disclosure also relates respectively to the strand-shaped article or strand portion to be cut, as long as the voltage permits, as may exist in the case of a power cable, and is immaterial. The power cable S is a high voltage power cable.

[0101] figure 1 The installation of a severed power cable 5 as a product to be cut 3 in an exposed groove 6 is schematically shown.

[0102] The cutting device 2 can be controlled remotely via a control device 7 which is hydraulic and, if applicable, also electrically connected to the cutting device 2 . The connecting dielectric hydraulic hose is provided with reference numeral 8 .

[0103] The control device 7 has at least one activation switch 9 . By a...

Abstract

A device is used to sever an electrical power cable for the transmission of high voltage. The cable has an insulation sheath, a screening layer and a conductive layer. The device includes a first frame having a first cutting blade mounted thereon, a second frame, and a measuring device mounted on the second frame. The first cutting blade is moveable relative to the measuring device. The measuring device is capable of measuring an electrical load on the electrical power cable and capable of terminating the severing of the electrical power cable. A method of using the device is also provided.

Description

[0001] This application claims domestic benefit to U.S. Provisional Application No. 62 / 100,639, filed January 7, 2015, the contents of which are incorporated herein in their entirety. technical field [0002] A method for cutting a power cable is provided, the power cable is used for high voltage transmission and has an insulating sheath and a shielding layer. Background technique [0003] Some methods are known and used, for example, when working on so-called buried cables, in particular installed and at least ready for operation. [0004] In particular, in the case of installed power cables for transmitting high voltages, there is a risk that they remain electrically loaded during the cutting process, which could lead to endangering the person who caused the cutting of the power cables. It can also cause damage to the cutting device. [0005] With regard to the known prior art, the problem is to specify a method of the type in question which in particular ensures the safe...
