Please try to think that:
1. Why we increase the dosage of crosslink, the deformation of the cable worse than 11 Mrad?
2. Why 11 Mrad and 14 Mrad fail, but 12 Mrad pass? If we cannot find out the root cause, we cannot control the quality in mass production.
3. When you test the hot set, please keep the sample in the oven with the load. Measure the elongation(hot set), and then, take the sample out of the oven and take the load away, wait until the sample cold down, test again(another test item, now we don’t use it).
