HF-8810 电线电缆曲挠试验机
FLEXIBLE CABLE FLEXING TESTER
IEC 60227-1、VDE0472、GB/T5023.2-1997

     本机试法是取试件约 5m 长，中段挠于规定直径之两个圆轮上，两端施加荷重，并接通电流，然后以 0.33m / sec 之速度，1m 之行程，移动圆轮，使试件往复弯曲拉伸，当断线或到达设定次数，会自动停机，取下试件评定其耐挠曲性质。 

     Cut off the cable about 5 m in length as being the test specimen which shall be kinked over the specified diameter of both wheels and each end has to be loaded with a weight。eanwhile each conductor of sample shall be loaded with a current。Later，at an approximately constant speed of 0.33 m/s to move the wheels over a distance of 1 m to make the specimen be reciprocally bent and tightened。When the specimen breaks down or the preset numbers are reached，the machine will stop automatically。Afterwards，take off the sample and adjudge the characteristic of flexibility。
