Description

Technical Field

[0001] This utility model specifically relates to the technical field of cable insulation testing equipment, and more specifically to a portable marine power cable insulation testing device. Background Technology

[0002] Due to the harsh environment on ships, such as humid air, salt spray corrosion, and mechanical vibration, these factors can adversely affect the insulation performance of marine power cables, leading to insulation aging and damage, and increasing the risk of cable failure. Therefore, it is necessary to regularly inspect the cables to prevent faults such as current leakage and short circuits, while protecting personnel safety and ensuring the normal operation of equipment. Currently, electrical safety personnel generally use portable megohmmeters to inspect cables. However, since the conductive clips used for electrical testing on megohmmeters lack external protection, electrochemical corrosion may occur in the humid environment on ships. This can not only damage the object being tested but also affect the accuracy of the test, posing certain hidden dangers to the safety inspection of cables. Utility Model Content
