PV cable Due to the particularity of performance and irradiation processing, the following points should be noted during irradiation:
a. Before irradiation, check whether the conductor of each cable head is fully grounded. It is forbidden to irradiate the cable without grounding.
b. The absorbed dose of the insulation core and sheath during irradiation shall be subject to the qualification of the heat extension test.
c. The surface of irradiated insulation core and sheath layer shall be smooth and clean without oil stain, with no obvious difference in color, no scratch, fuzzing, cracking, bubbles, etc., and the printing shall be clear and scratch resistant.
d. The traction and take-up speed shall be coordinated with the beam current regulation action to avoid over dose or under dose when the irradiation speed is increased or decreased.
e. The insulation core and sheath layer shall be fully discharged after irradiation, and shall be parked for 48h before moving to the next process.
