IEC60540 Cable Testing Equipment

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:

1. Diameter of samples: 2.5～12.5㎜

2. Diameter of pipe: 3,4,5,6,7,8,9,10,12,14,16(mm)

3. Diameter of test bar: 9.6,12.5,16,20,25,31.5,40,50(mm)

Test condition:

The diameter of the mandrel shall be between 4 and 5 times the diameter of the test piece.
