Description

Technical Field

[0001] The invention relates to the technical field of substation construction, in particular to a substation construction cable bending test device. Background Art

[0002] The cable bend test is a test method used to evaluate the performance and reliability of cables under bending stress. The following is some key information about the cable bend test: 1. The purpose of the test is to determine the durability of the cable under repeated bending, and to simulate the bending scenarios that the cable may experience in actual use. For example, during the connection and movement of the equipment, the cable will be bent to varying degrees. The test can predict whether the cable will have internal conductor breakage, insulation layer damage and other problems due to bending during long-term use, thereby ensuring the normal operation of the cable throughout the product life cycle and evaluating the flexibility of the cable. Flexibility is an important performance indicator of the cable, especially for some cables that need to be bent frequently or used in small spaces. The test can quantify the cable's ability to withstand bending. The degree of bending that the cable can withstand provides a basis for product design and material selection. 2. Test equipment Bending testing machine is usually composed of a fixture, a drive device, a control system, etc. The fixture is used to fix the two ends of the cable and bend it at a set angle and speed. The drive device provides power to make the fixture reciprocate. The control system can set test parameters, such as bending angle, number of bending times, speed, etc., and record data during the test. Measuring instruments such as resistance testers and insulation resistance testers are used to measure the electrical properties of cables before, during or after the test, such as conductor resistance, insulation resistance, etc., to determine whether the electrical properties of the cable change during the bending process.
