Test Criteria
Pass Criteria: During testing, no open circuit or short circuit in the tested sample until the machine stops running.
Fail Criteria: Sample experiences open circuit, short circuit between conductors, or short circuit between test sample and pulley.
Sample Configuration
- Sample selection: one-core, two-core, three-core
- Three-core voltage options: Adjustable 0V, 220V, 380V
- Power supply: three-phase, five-wire system (A, B, C live wires, N neutral wire, earth wire)
Application Scope
Suitable for performing dynamic flexing tests under load on flexible cables with rubber-plastic insulation and sheaths. The unit automatically stops upon detecting conductor open-circuit, short-circuit between conductors, or short-circuit between cable specimen and pulley.
Test Method
A test specimen approximately 7 meters in length is wound around two pulleys of specified diameter at its middle section. Weights are applied to both ends of the specimen, and electric current is passed through it. The pulleys move reciprocally over a stroke of 1 meter at specified speeds (0.33 m/min for two-pulley type or 0.1 m/min for three-pulley type), causing the specimen to undergo repeated bending and stretching. The test automatically stops when wire breakage occurs or when the preset cycle count is reached.
