Main functions:

        Test insulator bend and twist test (electronic control)。

Performance characteristics:

1.It can do 1 point bending test of insulators, and also can do 4 point automatic bending test in the circular direction。

2.This machine has 1 station, experimental bending and torsion test。

3.Lifting space adjustment adopts screw drive, linear guide guide, smooth transmission without sliding。

4.Real-time display of test force and deformation data。

5.Real-time display of test force-deformation curve。

6.It has the function of curve analysis, comparison, simulation and amplification。

7. When torsion is equipped with bolt locking flange function, easy to operate。

8.High measurement accuracy, high control accuracy, low noise。
