Description

Technical Field

[0001] This utility model relates to the technical field of cable testing equipment, specifically a cable testing instrument. Background Technology

[0002] A cable tester is a device specifically designed to detect various parameters and faults in cable lines. It can test the cable's conductivity, insulation resistance, and withstand voltage performance, and can also locate cable fault points such as short circuits, open circuits, and leakage. It is mainly used in the power, telecommunications, and construction industries to ensure the safe and reliable operation of cable lines.

[0003] Existing cable testers still have the following problems when in use: When using them, it is necessary to test the cable's withstand voltage, which requires the use of a cable withstand voltage tester. It usually uses pressure equipment to apply pressure to the cable until it is damaged, and records the instantaneous pressure at the time of damage. The pressure sensor is usually set at its test base. Since the cable is usually cylindrical, the single pressure sensor design on its bottom surface has a certain error when performing pressure data testing. Utility Model Content
