HF-8810 電線電纜曲撓試驗(yàn)機(jī)
FLEXIBLE CABLE FLEXING TTER
IEC 60227-1、VDE0472、GB/T5023.2-1997

     本機(jī)試法是取試件約 5m 長(zhǎng)，中段撓于規(guī)定直徑之兩個(gè)圓輪上，兩端施加荷重，并接通電流，然后以 0.33m / sec 之速度，1m 之行程，移動(dòng)圓輪，使試件往復(fù)彎曲拉伸，當(dāng)斷線或到達(dá)設(shè)定次數(shù)，會(huì)自動(dòng)停機(jī)，取下試件評(píng)定其耐撓曲性質(zhì)。 

     Cut off the cable about 5 m in length as being the tt 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 pret numbers are reached，the machine will s automatically。Afterwards，take off the sample and adjudge the characteristic of flexibility。
