Pendulum Hammer Impact Test Apparatus

IEC60068-2-75 Environmental testing - Part 2: Tests - Test Eh: Hammer tests, IEC60068-2-63, IEC62262 Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK code), IEC60439-5 Low-voltage switchgear and controlgear assemblies - Part 5: Particular requirements for assemblies for power distribution in public networks

This device is suitable for mechanical impact strength testing for electric cabinets and other sheet metal shells for items such as electric energy metering cabinets, substation cable switchboards and cable junction boxes.

Test sample
The shell of electric energy metering cabinets, substation cable switchboards and cable junction boxes and similar equipment

Equipment using the car structure, can be moved left, right, forward and backward, the upper and lower impact point height is fully adjustable 0-90°. The device is a low energy pendulum impact device for 2J and above.
