IEC60811 Cold Bending Test Device For Insulating Cable Test Equipment
The bending test apparatus confirms to:
IEC60540
IEC60811 standard
Product information:
The cold bending test machine is used for cold bend test of the circular insulation wire core whose diameter is small and
the sector-shaped insulation wire core which can not be used for dumbbell.
The apparatus shall be held in a refrigerator before and during the test.
The diameter of the mandrel shall be between 4 and 5 times the diameter of the test piece (see below).
The mandrel shall be uniformly rotated at a rate of one revolution in about 5 s and the number of turns shall be as specified in the following table.
Technical parameters:
