Bend test

   Bending test,seismic test of appendix of Eletrical Appliance and Material Safety Law(the first Supplementary Table twenty-fourth) which was changed in part to our specifications,performed in the following ways.

  Mount a sample of about 1.5m taked from the finished product,bending it to the bending test apparatus of FIG.2,at bending radius r=6D.

  At a rate of per minute 200 times at the device is bended a predetermined number of times. 

  At that time not rise to s short circuit between the lines,no crack about surface of the insulation and the exterior,and other abnormalities that there is no.
