Cov txheej txheem kuaj flexure ntawm kev kho mob cable yog raws li hauv qab no:
1. According to the test model, number of cores, cross-sectional area of cores, determine the diameter and load mass of pulleys A and B, sample test current and test voltage according to standard requirements.
2. Coj tus qauv txog 5m ntev thiab nruab cov qauv raws li qhov yuav tsum tau ua ntawm tus qauv. Nco ntsoov tias lub kaum sab xis ntawm lub axis ntawm lub pulleys A thiab B yog 45 degree nrog txoj kev khiav, thiab peb ntu ntawm cov cables ntsia nruab nrab ntawm lub pulleys yog nyob rau hauv kab rov tav. .
3. Adjust the limit clamps (D) at both ends to make the cable sag naturally, and add weights of appropriate quality to both ends and apply the load current and voltage specified by the standard.
4. Teem tus naj npawb ntawm reciprocation ntawm lub txee rau 1 lab reciprocating txav, pib lub flexure test ntaus ntawv, thiab lub trolley yuav txav mus los ntawm qhov kev ncua deb ntawm 1 meter ntawm qhov ceev ntawm qhov ntev li ntawm 0.33m/ s ua kom cov qauv reciprocate thiab khoov thiab rub stretch.
5. After the flexure test, all samples are tested for the voltage of the finished cable.
