gui chao cable news: notice of photovoltaic cable irradiation
from：guichao author：admin click： 427 addtime：2017-04-01 10:39:14
the properties and irradiation processing of low smoke halogen free flame retardant polyolefin,
therefore, the following points should be noted in irradiation:
a. to check whether the conductor of each cable head is fully grounded before irradiation, the cable is strictly prohibited in the absence of ground irradiation.
the absorbed dose of b. insulation wire core and sheath layer shall be qualified by the thermal extension test.
c. irradiated insulation core and sheath surface should be bright and clean, no oil, no significant difference in color,
it is not allowed to wear, fluff, cracking, bubbles and other phenomena, printing should be clear and rub.
when the d. radiation speed up and down speed, the traction and take-up speed should be coordinated with the beam adjustment action to avoid excessive dosage or low dose.
e. insulated wire core and sheath after the irradiation of the ground to fully discharge, and parked 48h, can be transferred to the next process.
