Cable Crush Testing Machine
Category：Life Cycle & Durability
Introduction
The Cable Crush Test Machine is designed to evaluate the crush resistance of electric vehicle charging cables in accordance with GB/T 33594. It automatically records the cable’s ability to withstand compressive forces. By changing the clamps, the machine can also perform flattening tests on copper or copper-alloy sheathed mineral-insulated cables with diameters less than 25 mm and rated voltages of 500V or 750V.
Application
The Cable Crush Test Machine is suitable for:
Electric vehicle charging cables crush resistance testing
Copper and copper-alloy mineral-insulated cable flattening tests
Testing of cables used in automotive, industrial, and electrical applications
