8. Handling & Safety Notes. Unroll from the drum without twisting the single core; avoid kinking at terminations; protect the sheath from UV and sharp edges during and after laying; run the site DC test and verify insulation integrity before energising; never exceed the 3.5 kV/5 min level for site checks unless the project allows otherwise.
9. Applications. Heavy low-voltage feeders, large motor and pump circuits, transformer secondary connections, main switchboard tails and industrial distribution risers — in trays, conduits, trenches, tunnels and ducts, indoors or in sheltered outdoor positions.
10. Packing & Ordering. Normally delivered 100 m per drum/coil, with standard marking (model, voltage, maker, year, length marks). Order: ZR-YJV 0.6/1 kV 1×150, with length and drum type. Reconcile all data against the factory certificate and GB/T 12706.1 / IEC 60502-1 test report before installation.
