Abstract

The invention discloses a device for pulling out a cable core, and the device comprises a strip-shaped cable clamping body; one end of the cable clamping body is provided with a cable fixing cavity along the length direction of the cable clamping body; the end of the cable clamping body which is provided with the cable fixing cavity is fixedly provided with a cable fixing tablet; the center of the cable fixing tablet is provided with a central hole for the cable core to penetrate through; and the other end of the cable clamping body is provided with a clamping palm for a tensile machine to clamp. The invention also discloses a method for pulling out the cable core. According to the device and the method for pulling out the cable core, the deformation and the damage of a cable insulation layer and a shielding layer are not caused, and the accuracy in a test result is not affected; no safety risk exists during operation, and the personal injury of an operator is not caused; and the technical requirements on operation are low, the operation time is short, and the overall efficiency of cable testing is improved.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a device and method for extracting cable cores. Background technique [0002] Due to its high reliability, power cables have been widely used in power systems. However, due to the large differences in the production level and production process of various cable manufacturers, the quality of power cables is uneven. In order to ensure the reliable operation of the power system, it is necessary to perform strict network inspection on the power cables. Among the testing items stipulated in GB12706 "Rated Voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) Extruded Insulated Power Cables and Accessories", insulation layer thickness measurement, conductor shielding layer thickness measurement, insulation shielding layer thickness Measurement, conductor shielding resistivity measurement and many other projects need to draw the core of the tested cable. The traditional method of extract...
