Description

Technical Field

[0001] The utility model relates to a testing tool, in particular to a testing tool for a cable wear resistance test. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating insulation layer. The cable has the characteristics of internal power conduction and external insulation. The material of the cable insulation layer is usually mainly PVC polyethylene, XLPE and rubber insulation layer.

[0003] When factories produce cables on a large scale, they need to sample and test the wear resistance of the produced cables to avoid a large number of inferior products entering the market.

Some cables that are not made of flame-retardant materials may cause fires due to overheating, and overheating of the grinding disc will also affect the results of subsequent tests.

[0004] Therefore, a cable wear resistance test fixture is designed. Utility Model Content
