EZ-50 Cable torsion testing machine

The EZ-50 is a newly developed digital display cable torsion tester.

First, the product overview

The EZ-50 is a newly developed digital display cable torsion tester. The machine is a horizontal structure consisting of loading, transmission, apply force, tracking, digital display, etc. It is suitable for testing the torsional performance of pipelines or pipe cables with a nominal diameter of Φ0.3-Φ50mm; rotation speed: 15, 20, 30 rev / min adjustable. It main test that cable or pipeline is capable of shorting or losing continuity when applied with a radial distortion of ±180°. Mainly used in factories, enterprises, scientific research departments, laboratories, workshops, cables and other industries, providing testing means for production and scientific research.
