Main functions:

      Electrical and mechanical failure load test to test the voltage applied state of insulators。

Performance characteristics:

• The main engine adopts the double space structure of the oil cylinder.

• The system can satisfy the conventional mechanical test when the voltage is not applied.

• The system is switched to manual valve control when the voltage is added;

• The whole test process is controlled by microcomputer, and the test parameters and result data are displayed in real time.

• The software automatically draws the curves of test force vs. displacement, test force vs. time, etc.

• The measurement mode of dynamic pendulum dynamometer solves the failure of system components in high voltage state.

• The composite insulated tie rod can insulate the equipment and improve the safety protection。
