Introduction
Product Introduction
The Cable Extrusion Tester is designed to evaluate the extrusion resistance of electric vehicle charging cables in accordance with GB/T 33594. The machine automatically records the extrusion pressure against the electric resistance, providing precise measurements for quality control. By changing the clamps, it can also test copper or copper alloy sheathed cables with a rated voltage of 500V or 750V and diameters under 25 mm, ensuring compliance with flattening and extrusion standards.
This tester is widely used in cable manufacturing, quality inspection laboratories, and research institutions to guarantee reliable and durable cable performance.
