Product information:
The HT Apparatus for impact test at low temperature confirms to the standard of IEC 60884 figure 27 and figure 42. The first one is fit for impact test of wire while the latter one is applied for the impact test of plug, socket, switch, wire and electrical conduit.
Technical parameters:
This device is used with the cryostat. It should be put in the sponge-rubber pad of 40mm-thickness. The height of falling: 10~250mm is adjustable.
