A: Mixing new‑batch irradiation‑cross‑linked PV cables
with aged legacy non‑irradiated cables creates mismatch on thermal‑expansion,
ageing‑rate and dielectric‑performance. Different material systems generate
uneven stress at transition joints under long‑time thermal‑cycling outdoor
conditions. Try to avoid hybrid‑laying two different‑material‑type PV‑cable
types within one string circuit. If hybrid‑connection cannot be avoided,
enhance joint sealing and increase thermal‑imaging inspection frequency for
transition splices, and document material‑difference in maintenance log.
