Cable tension testing device for heat insulation type power control cable

Abstract

The invention discloses a cable tension testing device for a heat insulation type power control cable. The device comprises a rack, a cable end part fixing tool, a wire clamp, a tension testing device, a cable temperature control device and a cable temperature control device fixing base. A cable temperature control device is transversely arranged at the upper end of the rack; the cable temperaturecontrol device is arranged along a long side direction of the rack; a plurality of cable temperature control device fixing bases are arranged at the lower end of the cable temperature control device;the cable temperature control device fixing base is fixedly connected with the rack; a cable end part fixing tool is arranged at one end of the cable temperature control device; and the cable end fixing tool is fixedly connected with the rack, and the other end of the cable temperature control device is provided with the tension testing device. By arranging the cable temperature control device, atemperature of the cable can be conveniently regulated and controlled, anti-drawing performance of the cable at different environment temperatures can be conveniently tested, testing precision is improved, and testing is more convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of cable production equipment, in particular to the technical field of cable tension testing devices. 【Background technique】 [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, usually a rope-like cable twisted by one or several groups of wires, each group of wires is insulated from each other, and often It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The cable pull-out resistance is an important performance of the cable, which directly affects the life and safety of the cable. Poor cable pull-out resistance is likely to cause damage to the cable. Breaking will affect the normal transmission of power, so it is necessary to perform a tensile test on the cable, and the ambient temperature of the cable is varied, so it is extremely important to test the pull-out performan...

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, usually a rope-like cable twisted by one or several groups of wires, each group of wires is insulated from each other, and often It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The cable pull-out resistance is an important performance of the cable, which directly affects the life and safety of the cable. Poor cable pull-out resistance is likely to cause damage to the cable. Breaking will affect the normal transmission of power, so it is necessary to perform a tensile test on the cable, and the ambient temperature of the cable is varied, so it is extremely important to test the pull-out performance of the cable in different temperature environments. The existing tensile test device can only test the cable at room temperature. The pull-out performance in the environment cannot measure the pull-out performance of the cable in different temperature environments
