Application
The Flexible Cable Flexing Test Equipment is used to detect
the damage degree of flexible cables with rubber insulation and
sheath after bending for a certain number of times under the
dynamic load.

- Fault detection and shutdown: when the actual test sample conductor
is open circuit, short circuit between conductors, short circuit
between cable sample and pulley, and has the functions of wire
break indication, phase to phase short circuit indication, wire
core and shell short circuit indication.
- Power requirements: AC380 (± 10%) V / 50Hz.
Equipment structure
- The control panel is located in the front of the machine to
facilitate observation and operation, and the power supply is
located at the back of the machine.
- The driving structure is concealed, with a neat and beautiful
overall appearance and easy cleaning.
- The pulley device is located above the machine. The pulley is a nut
locking structure, which is convenient for users to replace the
pulley and test different samples.
- Four universal casters with lock are installed at the bottom of the
chassis to facilitate movement. During the test, pressing the
caster lock can fix the machine without moving.
Components, materials and functions:
- Overall dimension of Flexible Cable Flexing Tester: 1880 * w530 *
h1500 (mm).
- Material of outer box: the shell is made of high-quality (t = 1.2mm)
electrostatic steel plate and processed by CNC machine tool. The
arc shape is beautiful and generous. The surface of the shell is
sprayed with plastic, which is more smooth and beautiful.
- Pulley material: high quality aluminum, surface polishing.
- Weight material: 45# surface thickening and electroplating
treatment.
Mechanical drive system:
- The Flexible Cable Flexing Test Equipment adopts Taiwan DC
reduction motor + sprocket chain structure.
