It applies to test the mechanical collision strength degree when the electrical equipment shells collide external objects.
This apparatus is designed and manufactured according to IEC 60068-2-75, the front end of the pendulum rod is connected to striking elements, adjust the pendulum rod to a certain height and release it, then the pendulum rod swing freely to impact the test sample surface within a define area. Different equivalent mass striking elements are corresponding to different impact energies, and applies to different electrical equipment enclosure strength test.
The shell of electric energy metering cabinet, substation cable switchboard and cable junction box and similar equipment.
The frame of this device is welded by stainless steel, the structure is compact and durable. The mounting brackets can be adjusted up and down, and the impact angle is 0-90 ° adjustable, the whole test apparatus is easy to be operated. The device is a high energy pendulum impact device for 2J and above.

The test apparatus consists basically of a pendulum rotating at its upper end in such a way as to be kept in a vertical plane. The axis of the pivot is at 1 000 mm above the measuring point. The pendulum is composed of a nominally rigid arm and of a striking element complying with the requirements of table 1 .
For testing heavy, voluminous or difficult to handle specimens, a portable pendulum may be used. It shall comply with the above description but its pivot may be fixed directly on the specimen or on a movable structure. In this case, it shall be ensured that, before the tests, the axis of the pendulum is horizontal, that its fixing is sufficiently rigid, and that the impact point is in the vertical plane passing through the axis.
In all cases, when the pendulum is released, it shall be allowed to fall only under the influence of gravitational force.
