Abstract

The invention discloses an optical cable and electric cable outer jacket coating force measurement device and measurement method, and relates to the field of electric cable and optical cable performance testing. The optical cable and electric cable outer jacket coating force measurement device comprises an outer jacket pulling rod, an outer jacket clamping sheet and a clamping mechanism. The outer jacket pulling rod is fixedly connected with an up stroke hook of a tension tester through a pin and used for receiving and fixing a sample to be tested. The outer jacket clamping sheet is inserted in the lower end of the outer jacket pulling rod in an embedded mode. The clamping mechanism is located below the outer jacket clamping sheet. The 15-30cm distance is kept between the clamping mechanism and the outer jacket clamping sheet. The clamping mechanism is fixedly connected with a down stroke hook of the tension tester through a pin. According to the optical cable and electric cable outer jacket coating force measurement device and measurement method, the locating function of the outer jacket clamping sheet and the clamping function of the clamping mechanism are used, the tension function of the tension tester is cooperated, the coating force of an electric cable and optical cable outer jacket and the outer jacket coating force curve can be accurately measured, and theoretical bases are provided for studying the electric cable and optical cable tensile performance and the PE jacket material heat retraction performance.

Description

technical field [0001] The invention relates to the field of performance testing of cables and optical cables, in particular to a measuring device and a measuring method for the coating force of an outer sheath of an optical cable. Background technique [0002] Tensile performance is an important performance index of cables and optical cables. In the actual production process of cables and optical cables, the ratio of molds, the difference in water tank temperature, the difference in shrinkage of sheath materials, the difference in tension of aramid yarns, and the differences in aramid yarn The difference in yarn covering state and the difference in the state of other auxiliary components in the optical cable have a great influence on the tensile properties of the cable and the optical cable. Cable and optical cable tensile tests must be performed after they are cabled. Once abnormal production occurs, it will bring huge losses. The size and tension curve of the outer sheat...
