IEC227-2 and IEC245-2 Two-three Wheel Flexible Testing Machine for
Wire Winding
Application:
Two-three-wheel flexure is suitable for measuring the mechanical
strength of the rated voltage of 450/750V or less, two or more
cores of PVC insulated cable or rubber insulation and
extra-flexible wires, and its performance structure shall meet GB/T
5013.2-2008, GB/T 5013.8-2008 and GB/T5023.2-2008 IEC227-2,
IEC245-2, UL1581, IEC60227, IEC60245-2 standards. The instrument
should have the features of novel design, reliable performance
structure, convenient operation, dual use of one machine, and high
accuracy of test data. Flexible cables for rubber and plastic
insulation and sheathing are tested under dynamic load conditions
and the following faults are detected during the test and shut
down:
1 conductor short circuit
Short circuit between 2 conductors
3 Short circuit between cable specimen and pulley
Features: It has the function of disconnection indication, short-circuit
indication between phases, short-circuit indication of the core and
the shell.
